Do You Know What Hybrid Fabrics Are?

The term hybrid refers to a fabric that has more than one type of structural fiber in its construction. In short, hybrid fabrics are woven from a wide variety of different fibers.

 

Hybrid fabrics are mainly distinguished by low areal weights, cost savings.

 

They are often used for their striking cosmetic appearance in composite components. Although hybrids are most commonly found in 0/90 woven fabrics, the principle is also used in 0/90 stitched, unidirectional and multiaxial fabrics.

 

The common hybrid combinations are Carbon / Aramid, Aramid / Glass and Carbon / Glass. The latter typically look like carbon, as the glass is transparent when wet out. When designing with carbon / aramid fabrics, note that aramid fiber has a negative axial coefficient of thermal expansion (CTE) like carbon fiber, but the radial CTE is twice that of epoxy. This can lead to micro-cracking in laminates and wicking of moisture into the laminate over time. In non-cosmetic carbon / aramid laminates it may be better to use an aramid liner separate from the structural laminate rather than using a hybrid.

 

If you are looking for the hybrid fabrics supplier, Taiwan Electric Insulator Co. Ltd. is a wonderful choice. You can find a variety of aramid fabrics, carbon fabrics, composite fabrics, hybrid fabrics and so on products on their website. Need more details? So what are you waiting for?

Liquid Crystal Polymer (LCP) – A relatively unique class of partially crystalline aromatic polyesters based on p-hydroxybenzoic acid and related monomers. Liquid crystal polymers are capable of forming regions of highly ordered structure while in the liquid phase. However, the degree of order is somewhat less than that of a regular solid crystal. Typically LCPs have outstanding mechanical properties at high temperatures, excellent chemical resistance, inherent flame retardancy and good weatherability. Liquid crystal polymers come in a variety of forms from sinterable high temperature to injection moldable compounds.

 

A number of liquid crystal polymers (LCPs) were produced in the 1970s which displayed order in the melt (liquid) phase analogous to that exhibited by non-polymeric liquid crystals. However, the commercial introduction of liquid crystal polymer resins did not occur until 1984, at that time liquid crystal polymers could not be injection molded. Today, liquid crystal polymers can be melt processed on conventional equipment at fast speeds with excellent replication of mold details and efficient use of regrind.

 

Characteristics of LCP

 

  • l Molecular chains align themselves when molded, and this generates a self-reinforcing effect, Thereby resulting in extremely high strength and elastic modulus.
  • Despite having a high elastic modulus, very much superior vibration absorbing characteristics are exhibited.
  • Linear expansion coefficient in the flow direction in particular is very small, exhibiting a value an order of magnitude less than conventional plastics and on a par with steel.
  • The thinner the product, the higher the proportion of the oriented surface layer, so greater strength and elastic modulus can be achieved the thinner the product.
  • Because of its microcrystalline structure, LCP possesses superior deflection temperature under load (180-26 0°), continuous usage temperature (200-24 00°C), and solder heat resistance (2600°C for over 10 s, 310 0°C for 10 s), despite its relatively low melting point.

 

Applications in LCP

 

  • Automotive industry: Automobile combustion system components, burning pumps, insulation components, precision components and electronic components, etc.
  • Electrical and Electronics: High-density connector, coil planes, bobbins, the substrate carrier, capacitors case, socket, surface-mount electronic components, electronic packaging materials, printed circuit boards, braking equipment and lighting equipment, etc.
  • Home-use Electric Appliances: Microwave oven kitchen containers and food containers, etc.
  • Mechanical industry: Distillation column filler, valves, pumps, oil well equipment, measurement equipment parts, seals and bearings, etc.
  • Medical industry: Surgical equipment, intubations, knives, sterilization trays, laparoscopy and dental materials, etc.

 

Manufacturer of LCP

 

For quality liquid crystal polymer LCP, Prochase Enterprise Co., Ltd. is one of the excellent choices of manufacturers for customers. If you need more information about LCP, try to check out Prochase’s website: www.prochase.com and let the company know your demands.

Victor Taichung P76 Vertical Machining Center

High performance milling has just been taken to a new plateau with the arrival of the new P76 vertical machining center from Victor Taichung. The new 3-axis VMC only recently arrived in the UK and it is already setting new standards for performance, productivity and precision among the subcontract machining community.

 

Quality is assured with Victor Taichung and this latest addition to the stable at the Rochdale Company is the epitome of a high quality machining center. The new P76 incorporates a 30 tool ATC that can change tools in a blistering 1.6 seconds with a chip-to-chip time of 4 seconds. This speed is matched by the rapid feed rates of 48m/min in X and Y axes with 32m/min possible in the Z plane.

 

Not only does the new P76 have the facility to speed around its X, Y and Z work envelope of 760mm by 500mm by 510mm, the machine also demonstrates rigidity and stability through its BBT-40 face and taper contact spindle configuration and the certified meehanite structure that has an extremely wide base of 1166mm. Whilst the BBT spindle system enforces rigidity through the spindle nose and cutting tool to improve tool life, cutting speeds and feeds; the exceptionally wide casting base dampens vibration and adds stability. The result is the ability to conduct heavier cutting at higher speeds and feeds, which will certainly improve productivity. Furthermore, these characteristics will enhance surface finish and precision for the end user.

 

To increase material removal rates, the P76 has an 18.5kW spindle motor that delivers high torque levels throughout the speed range that reaches a top spindle speed of 12,000rpm. Accepting a maximum component weight of 500kg on its 840mm by 500mm table, the new P76 machining center is loaded with a range of standard accessories that includes a fully enclosed splash guard, FANUC 0i-MF CNC control unit with a user friendly 10.4 inch monitor and spindle oil cooler to maintain performance and longevity. Additionally, the P76 offers rigid taping, remote MPG, 3-step warning light, leveling pads, auto power-off and a screw type swarf removal system.

 

The base model of the new P76 is very well equipped to meet the demands of the modern machine shop. However, for end-users looking for a higher-specification solution, Victor Taichung can tailor the machine to the needs of the customer with optional extras that include a 40 tool ATC, coolant gun, automatic tool length measurement, auto part measuring and even a 4th and 5th axis interface. For enhanced precision and meeting the needs of high speed machining, the P76 can be configured with a 15,000rpm spindle, linear scales, rotary tables, oil skimmer, automatic doors, through spindle coolant, a Heidenhain TNC-620/640 CNC control and much more. For more information on how the new compact powerhouse from Victor Taichung can improve your machining performance, call Victor Taichung.

The sanitary ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.  The handle or lever will be in line with the port position letting you see the valve’s position. The ball valve along with the butterfly valve and plug valve, are part of the family of quarter turn valves.

 

Using ball valves in sanitary applications has some pluses and minuses. Perhaps the greatest benefit of using sanitary ball valves is that they usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications and are often preferred to sanitary butterfly valves, diaphragm valves or seat valves. They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose. The other big advantage ball valves have is that they are the highest pressure rated sanitary valves on the market.

 

Principles of Operation

 

Sanitary ball valves, as the name implies, have a ball with a hole drilled through the center swivel mounted with the valve body. When the hole in the ball is oriented in the same direction as the pipe, this will result in full flow rate. As the hole in the ball is oriented away from the direction of the pipe, the flow rate will be restricted and finally cut off completely when the hole is oriented 90 degrees to the pipe direction.

 

Automation

 

Like sanitary butterfly valves, most sanitary ball valves can be highly automated.  Ball valves are offered with stainless steel actuators for all sizes.  There are different switch packages available which to mount to the actuators. Double rack and pinion pneumatic actuators are the standard for ball valves, because they are ¼ turn valves.  Also the same as the butterfly valves, ball valves have a large offering of different ¼ turn actuators on the market.

 

Other Features and Benefits

 

Many different manufacturers offer their version of a ball valve although the operational features are very similar. In the market of ball valves there are many different alternative choices so that potential customers are easily able to find another choice. For this reason it is important to decipher a customer’s needs for the application at hand. This will make it possible to choose the one that will be a quality performer at a good price.

 

Like the butterfly valve, a ball valve is available in 316 as well as AL6XN and Titianium material. This type of construction material is not available with all manufacturers, as well as, it can be difficult to find MTRs and C of C’s to go along with the desired valve.  There are multiple handle styles that are offered with the ball valve as well, such as, pull stop with a locking mechanism and trigger handles. Ball valves have the luxury of coming with many different connection styles in order to be able to fit into a customized sanitation process line.

 

Are Sanitary Ball Valves Really Clean?

 

As we discussed with the butterfly valve. What is considered “sanitary” is relative to each end user. The fact that sanitary ball valves are constructed of 316 stainless steel, have FDA approved elastomers and have Tri-clamp or tube OD butt weld ends puts them in the sanitary realm. But you really cannot truly clean it in place. Ball valves have cavities and crevices behind the ball that gather product when the valve in being actuated. These areas do not get clean during CIP. To truly clean the valve, you have to take it apart.  Even with newer designs of ball valves having FDA approved cavity fillers to help limit product build up on the inside of the vale it is inevitable that product will still accumulate around the outside of the ball and orifices. Because of the sanitary ball valve do not carry the 3A rating.

 

TARGET VALVE is the professional valves manufacturer in Taiwan. You can find a variety of valve products on their website. Such as 1 pc ball valve, economic ball valves, flanged ball valves, multiway ball valves, and sanitary ball valves etc. Learn more details, welcome to check out their website and feel free to contact them directly.

Pull stud is the tension part between the principal spindle of the boring milling CNC machine tool and the tool holder. It is also called pull head, connecting pull head, thread pull head, tool holder pull head, tool holder pull stud, tool holder joint, fastening pull stud and tool holder tensioner, etc. Due to its small volume and low value, its importance in work is easily neglected by people. To better develop the role of the lathe, it is necessary to have a understanding about the pull stud and lathe tension mechanism.

 

Pull Stud Stand and Its Combination:

 

Pull Stud Is The Spare Part Fixed At The Tail End Of Various Tool Holders Through Thread.

 

The tension mechanism inside the principle spindle of the lathe tensions the tool holder in the principal spindle by use of it. The tensioning is maintained by replying on a group of springs. After tension is realized, the prolapse of tool holder and tool from the high-speed rotary principal shaft can be avoided sufficiently.

 

Pull stud is designed according to the standards of tool holder and related part of the lather. Due to the various standards for the tool holder, the lather tension mechanism also differs. Therefore, the united standards cannot be formed for the pull studs. Sometimes, the two ends of the pull studs live up to certain standard (like ANSI, DIN, ISO or JMTBA). However, sometimes, the mixture form (the thread part is adapted to the tool holder part of ISO standard while the pull stud head is also adapted to the lather of ANSI. In this case, such mixture combination can bring about a lot of different pull studs) also exist. In case of inappropriate selection of pull studs, the accident will be caused when using the tool holder after it is installed in the tool holder.

 

Selection of Pull Stud:

 

Facing Various Pull Studs, How to Find Out The Specification And Type You Need?

 

It is better to select the pull studs according to the instruction of the lather. The drawing or type of the pull stud will be given out in the instructions of lather by most lather manufacturer. Additionally, the determination can be made after measuring the pull studs for the lather. Most pull studs are of 10-12 dimensions. It is necessary to provide the details to the supplier in case of ordering. However, the attentions should be especially paid to main three parts: namely the angle of pull stud, the distance from the base level to this angle and the thread type. These three dimensions are easily measured. If a national lather (Actually, the taper hole of the principal spindle is British system dimension, it is just labeled by changing it into the metric unit) and a batch of tool holders of British system taper are bought for a workshop. As for the pull studs, the thread is labeled with America system (adapted to the tool holder), the metric system shall be used for other dimensions and adapted to tension mechanism of lathe.

 

If you are looking for pull studs manufacturer, Shin-Yain Industrial Co., Ltd. is a wonderful choice! This company is a well-known tool holders manufacturing expert in Taiwan. Shin-Yain can offer a variety of tool holders, collet chucks, pull studs, and shrink fits to you. More details, try to check out Shin-Yain’s website: www.syic.com to gain you need.

A shearing machine is an industrial equipment with rotary disks and blades used to cut hard iron sheets and metal bars. The term shearing means to apply a high pressure tool on a metal bar once to remove a part of the metal. All metal shears use the same technique in cutting where there is a fixed upper blade, a lower blade and an adjustable clearance separating the two. When a force is applied on the upper blade it forces the lower blade to cut and separate the metal into two.

 

Shearing machines are categorized depending on the shape of its blade, linear or circular.

 

Linear shearing machines are used to cut metal with a thickness of over 2mm and they are operated with hydraulic power or hand operated machines for thinner metals.

 

Circular shearing machines are used to cut circular blanks and rings from metal and are operated by an electric motor. The best types of metal for shearing are bronze, aluminum, brass and mild steel. Metal shearing is cost effective and easy and hence preferred in industries and even homes.

 

Types of Shearing Machines

 

  1. Bench Shear – The word bench is because the machine is mounted on a bench to increase its mechanical ability. It is used to cut rough shapes of medium sizes of metal. However, small bench shearing machines are fitted with ground cutting blades and are light weights making it easy to have clean and fast cuts.

 

  1. Guillotine – This means that the machine is hand or foot powered and sometimes mechanically powered. The material to be cut is first cramped with a ram and a moving blade goes down and shears the metal. a power shearing machine consists of a shear table to put the material being sheared, a a holding device to hold the material in place to avoid movement, a gauging device to make sure the material is in the right place and the lower and upper blades to do the cutting.

 

  1. Power Shears – This type of a shearing machine is electrically powered to shear large pieces of metal regardless of size. Alternatively they can be powered with hydraulics to cut metals that are too bulky for transportation.

 

  1. Throat – Less shear- This means that the metal being cut can be moved around the cutting blade freely so it’s flexible. It’s used for complex cuts and curves.

 

Advantages of Using Hydraulic Shearing Machines Over Mechanical Models

 

  • Hydraulic shearing machines are fast and accurate and make it easy to cut a lot of metal in factories.
  • Hydraulic shears don’t require a lot of maintenance as mechanical models and hence are cost effective.
  • Hydraulic shears are usually compact machines and hence take up less space even though they apply the same kind of pressure as mechanical shearing machines.
  • Hydraulic shearing machines secure metal with cramps while cutting hence ensuring smooth cuts and even 90 degrees cut. There are a wide variety of hydraulic shearing machines in the market to cater for all sizes of metal.

 

How to Use Hydraulic Shearing Machines Safely?

 

  • Always have specialist operators to work on the machine
  • Maintain cleanliness in the machine and follow the operating rules to avoid hazards.
  • Always make sure to switch off power of the machine after use.

 

Conclusion:

 

Hydraulic shears are more effective and easier to use than mechanical machines but should be handled with care by qualified personnel only.

Impacting important characteristics such as ride quality and feel, a frame is often the defining feature of your favorite bike. So regardless of whether you’re getting stuck into a dream bike build, considering a new ride or are just a sucker for the technical detail, we’ve put together this handy guide to help you better understand the foundation of your bicycle.

 

Often referred to as the heart of a bike, a frame can be made from either carbon fiber, aluminum, titanium, steel or a combination of these materials. Each bicycle frame material offers a list of differing characteristics that will affect the cost, comfort, weight, stiffness, strength and durability.

 

It’s worth noting that it’s often how the chosen material is used by the engineers and manufacturers that matters most, and this is something that each brand will typically play with. Before we jump into the details, it’s worth considering the following factors when deciding what material is best for you;

 

  • Weight: Your bike needs to be strong enough to carry you and any extra luggage you plan on carrying in the form of panniers, racks or mounts. Each material will have different strength properties, fatigue rates and impact resistance but there is always a trade-off between weight and durability. Another aspect of weight to consider is how important having a lightweight bike is to you. For example, if you’re chasing performance advantages than having a light weight bike would be higher on your list.

 

  • The Purpose of The Bike: If you plan on racing then a stiff, lightweight bike is the ideal choice, narrowing the type of materials to choose from. Conversely, if you are touring or planning a riding adventure that requires long hours in the saddle and the ability to carry items, then durability is the priority and again, narrows the type of material to choose from.

 

  • The Area You Ride: It may not be apparent that your postcode could influence the type of material your bike is built from, but consider a material like steel that will rust in wet, humid climates. A material like aluminum might be a better choice given the conditions while still providing similar characteristics to steel.

 

  • How Long You Plan On Having The Bike: All materials will fatigue over time but some faster than others. Steel will rust if not taken care of but is more durable than aluminum over the long term. Carbon fiber and titanium frames have exceptionally high fatigue rates meaning they will last and last and last.

 

  • Your Budget: Budget is often the biggest factor in choosing a bike and consequently its material. As a generalization, in order of most expensive to least expensive, titanium takes the cake, followed by carbon fiber, aluminum and steel. As always, the tradeoff between what you are willing to spend for what outcome is the key consideration.

 

To help provide more clarity on the various bike frame materials available, we’ve summarized each material type, its properties, characteristics and more importantly how they translate into ride quality. But, today I only introduce the material part of steel. For more details about other materials, please click here: Bike Exchange

 

Steel

 

Ah steel, the no fuss workhorse of bike frame materials. Steel was the universal choice of racing bike frames until aluminum appeared in the 1970’s and 1980’s and carbon fiber took over in the 1990’s.

 

There are two distinct types of steel used in the bicycle industry. The first is high tensile, or otherwise known as ‘Hi-Ten’, this is a cheaper grade steel commonly found in cheaper bikes, especially those from department stores. It offers an incredibility poor strength-weight ratio and so manufacturers will typically use this material in order to hit low price points. By comparison, higher-end steel bikes are likely to use chromoly, or CroMo for short (generally short for chrome molybdenum) steel, which as an alloyed steel offers superior strength properties to Hi-Ten and so can be butted and made thinner/lighter.

 

Steel is inexpensive, exceptionally durable, highly resistant to fatigue, easily repaired and easy to work with. Unlike carbon fiber and aluminum, damage to a steel bicycle frame is typically easily repaired. Somewhat surprisingly despite its strength, steel offers good levels of compliance thanks to its elastic properties. The downside of steel is that it is prone to oxidization (rust) and carries a weight penalty over other materials.

 

Touring and adventure bikes are commonly made from steel thanks to the exceptional durability and strength on offer. This enables riders to carry large amounts of luggage without compromising the bikes performance. Steel also features heavily on entry level and recreational bikes where weight isn’t such an important factor.

 

  • Pros of Steel: Cost and ease to manufacture, strength, durability.

 

  • Cons of Steel: Weight, corrosion resistance.

 

How It’s Made

 

Joining steel tubes together involves similar welding processes to aluminum frames, but further options exist including ‘Brazing’ and the use of lugs. Brazing is similar to TIG welding but uses a ‘filler’ material that is melted and used to join the tubes. The filler material is commonly silver or brass but could be a myriad of other alloys too. Lugs act as connectors at junction points of the frame, creating a sleeve for the tubes to slide into. Prior to constructing the frame, the ends of the steel tubes are precisely cut to fit perfectly into the lugs and brazed together. The use of lugs creates an immensely strong joint, and being an older manufacturing technique carries a side perk of giving a bike a ‘classic’ look.

 

Steel bicycle frames are perhaps the easiest frames to repair due to the availability of the equipment and supplies, as well as the material’s resistance to repeated heat. For this reason, steel is a great option for commuters, recreational cyclists and touring riders that need a highly durable bike.

 

If you want to get more information about bike frames, I recommend that you can visit the website of Maxway Cycles Co., Ltd.: www.maxway-cycles.com. Maxway is a leading manufacturer of steel bicycle frames and other kinds of bike frames. The company has built up solid relationship with a lot of steel bicycle frame manufacturers in Taiwan who supply high quality steel bike frame, bicycle frame products at decent prices.

Grid tie inverter is an innovative concept in solar energy technology that can help today’s homeowner offset high energy costs while protecting the environment. These devices differ from the stand-alone solar inverters that many homeowners use to generate their own electricity in that they tie in to the utility power grid, making it possible for energy to flow in both directions (i.e. to the customer and back out to the grid).

 

Thus, grid-tied solar inverters don’t limit the power generated by the system to the homeowner’s exclusive use, but rather, by allowing users to reroute unused power back to the grid, they enable consumers to sell that power back to the utility company. This revolutionary concept is the means by which solar technology is putting unprecedented power into the hands of the consumer, in more ways than one.

 

How Grid-Tied Solar Inverters Work and What They Do.

 

Grid-tie inverters are the commonly referred to as the brains of a solar system. A photovoltaic module (solar panel) converts sunlight into electricity, using semiconductors that react to the photons in the light. Grid tie inverter systems convert direct current (DC) to alternating current (AC), making the DC energy delivered by solar panels compatible with the rest of the utility grid.

 

These systems work by using sophisticated tracking technology that senses and adjusts the system’s voltage as needed to ensure that it matches the grid’s AC output voltage, thereby enabling the surplus electricity to flow back to the grid. Without this technology, the power would only be able to flow in one direction: from grid to customer. With it, the vital electricity flows from grid to customer, with the unused power flowing back to the grid again. That way, when the customer’s system generates less electricity than needed, the system draws enough power from the utility grid to make up the difference, and when the system generates more power than needed, the excess is diverted back to the grid.

 

When a grid-tied inverter wakes up in the morning by detecting a minimum voltage output from a solar array, it then looks to the utility grid to see if it can detect electricity. If it detects the power from the grid, it then looks at the frequency of the AC utility electricity to see if it is pure sine wave (60 Hz) + – a very narrow parameter. If “all is well”, the inverter then turns on and begins converting power from the solar panels and exports any excess power produced in the home onto the public utility grid.

 

“Power” to the People

 

Like many other aspects of modern technology, the grid tie inverter lets the consumer play a much more significant role in, today’s marketplace. In addition to allowing homeowners to generate electricity for private use (an innovative enough concept in itself), the inverter also allows the consumer to benefit from the energy that exceeds the customer’s own immediate requirements. This incentive has encouraged many homeowners to consider solar power, lessening their individual and collective burden on the environment, conserving the earth’s dwindling natural resources, and helping to meet our country’s growing energy needs.

 

Spinning the Meter Backwards

 

The capacity to deliver excess power back to the utility company through the delivery grid has come to be known as “spinning the meter backwards.” This phrase is an apt descriptor for the bottom-line outcome that grid-tied solar inverters provide, since they actually reduce, or eliminate, the amount of metered power the consumer must purchase from the utility company. Yet, spinning the meter backwards only goes so far, since it can only be used to offset the cost of electricity actually used by the customer. While the utility company is required by law to purchase the excess electricity generated by a grid-tied solar inverter system, once the amount of energy sold to the utility company matches the amount used during a given year, there is no further financial benefit to using the system. In other words, don’t allow someone to oversell you a system that will produce more than you require or it will dramatically reduce your return on investment.

 

How is “Grid-Tie” Inverters Different?

 

Most houses and commercial buildings that have a solar array as a source of electricity are also connected to their local power grid. When the electricity demand of the building is greater than what the solar array can provide, the balance can be drawn from the grid, but when the array is producing more power than is needed, the excess electricity can be sent out onto the grid to provide power for other people to use. This connection has to be managed carefully, however. The electricity has to be delivered to the grid in a form and at a power level that the utility’s system can accept. Also, if the utility suffers a power outage, the inverter has to be able to sense the blackout condition and immediately shut off the connection. This helps protect the safety of any utility workers who are trying to repair the grid and get it back into operation; a stray source of electricity can cause injury or even death to a line worker who is working on supposedly shut-down system.

 

New Technology, More Choices for Inverters?

 

Modern grid tie inverters are designed to operate with a minimal loss of power in the transfer from the solar array to the utility grid. To maximize power production, main stream inverter companies like SMA, SolarEdge, and Enphase have designed these precisely engineered devices to feed the maximum power onto the grid. Commonly called NET metering, any excess power produced is deducted from the power consumed at night and measured each month by the utility company and reported to you in your monthly bill.

 

Solar irradiance is dependent on temperature characteristics and the modern inverter must constantly adjust to achieve maximum power point tracker (MPPT) for climate conditions and cloud cover. To do this, inverters adjust the voltage so the system runs at its maximum power output at any given moment of the day. Additionally the inverter in most cases, records the operating data from the system which can be stored and reviewed in either real time or later by calling up the data. The newest trend in grid-tied inverters are high-frequency (HF) transformers in place of heavy coils and “H” bridge used in converting DC to AC power. High frequency transformers have lower efficiency losses and are smaller and lighter.

Side Release Buckles and Other Fasteners

 

Whether you make paracord survival bracelets or other projects which require side release buckles, this article will show you some cool options and some other ideas you may not have considered for fastening your bracelets.

 

Buckles, in one form or another, are the most common way for fastening bracelets and other gear and there are so many types of buckles to choose from and ways to fasten them. Some of the buckles are metal, but more are plastic (less expensive). There are buckles with whistles built in and of course, they come in many different sizes.

 

Some people choose to make plain survival bracelets with nothing more than a knot and loop fastener. For the ultra-crafty people or those wanting to do something different, you can weave beads or other toggles on one end of the bracelet and then a simple loop on the other. Here we’re going to take a look at some of the more common fasteners that most of us use in our projects. In the end I think you’ll find some great ideas here for your next project.

 

Plastic Side Release Buckles Are Very Popular and They Come in So Many Different Sizes and Designs

 

For many people plastic side release buckles are their first choice because they are very affordable, and if you’re making bracelets and other projects as a hobby, well, you probably don’t want to spend a fortune on buckles. Also, if you’re making bracelets for a fund raiser or to re-sell then you want to maximize your profit, so again, plastic buckles would be the obvious choice.

 

The most common size of buckle used for paracord bracelets is 16 – 19 mm (5/8 or 3/4 inch). This measurement is the width of the hole in the buckle through which you place your strap or paracord. Because these plastic buckles are so affordable, you can get a few different sizes and experiment to find out which size, and which type of buckle you like best. While all of those mentioned in this section are side release, they don’t all have the same look and feel—some release easier than others, some are more robust (higher quality plastic), and some buckles are more rounded (contoured) and have a generally better feel while wearing.

 

There are also single adjusting and double adjusting buckles. Double adjusting simply means that there are two slider holes on each end of the buckle. On a backpack, for example, this would allow you to cinch up and tighten a strap from both sides. For a survival bracelet with paracord you don’t have the need or capability to adjust, so look for buckles with only one slider hole on each end if possible, for a better look.

 

Of course we also need to discuss the purpose that the buckles will serve. If you are planning on using them for a gear strap (say on a backpack or day bag), then you might want a larger or at least heavier duty one. If it is simply for looks and on a paracord bracelet, then the smaller plastic buckles will work fine.

 

If you’re planning on making a bracelet for a survival or safety use, maybe using some reflective paracord, then it might be a good idea to use buckles that have a whistle built in like the one pictured here. For the most part these whistles work alright, but they aren’t the loudest thing you’ve heard. That being said, for a lost hiker, or a jogger trying to summon help, they will do the job. And they look kid of cool, too.

 

Metal Side Release Buckles Give Your Project Added Strength

 

And of Course the Ultra-Tough Look That You Want in a Survival Bracelet

 

There are many reasons why people choose plastic over metal side release buckles, and perhaps the two biggest reasons are 1) the cost increase by using metal buckles is significant if you use a lot of them, and 2) there’s added weight and bulk when using metal. However, there are still applications where metal is the right choice.

 

There are far fewer style choices when it comes to metal buckles, due to their decreased demand and also because of the relative greater difficulty and cost in manufacturing. In tactical applications you will almost always see plastic being used whenever possible, because it decreases the magnetic presence of the wearer (think bombs and IED’s), and also because there are no spark concerns, nor are there any rust related issues to contend with. Finally, plastic buckles rely on the tension created naturally by the displaced connectors when they’re snapped into place. Metal buckles, on the other hand, rely on small, internal springs to retain their tension… meaning that they can wear out and fail, while the plastic buckles are much more likely to retain their shape and strength over time.

 

There are no bells and whistles (literally) on the metal buckles, and your choices are limited to basically the size you want.

 

Plastic Buckles with Side Release Are Cool

 

But These Steel Shackles Give You the Ultimate Survival Look

 

Are you looking for some really cool buckles to make something really unique, or do you have a project that requires something more robust than plastic buckles? There are tons of things to be made with paracord beyond bracelets, and so many ways to make them all. More and more people are getting creative and making their products their own. And lot’s of people prefer the rugged look of the metal shackle buckles. I admit it, I like them, too!

 

As you can see, using this type of buckle gives much more strength and reliability than a typical side release buckle. Of course the cost is higher, but the end product is clearly much more appealing. Again, it will boil down to the project. For fund raisers you will almost certainly want to stick with the plastic buckles.

 

One of the Coolest Paracord Projects with Buckles

 

Make a Dog Collar With These Large Reflectors, Side Release Buckles!

 

If you have a dog, or know someone who does, you can make a really cool personalized gift: a reflective dog collar. Using ultra-cool reflective paracord colors and this large side release buckle that includes a reflector, you have the makings for something special.

 

No dogs? These make great luggage straps—the kind you wrap around your luggage to ensure that it doesn’t pop open when airport security or those guys on the conveyor belts throw it around. There are lots of ways you can make something really creative with these plastic buckles! Check it out.

 

What Are Your Thoughts on Buckle Types? Side Release or Shackles?

 

Ok, now that you’ve had a chance to look at some of the different types of buckles, including the side release and metal shackle types, here’s a question. If you were going to make a paracord bracelet, right now, and had both types in front of you, which would you use? More details check out here: Do you prefer plastic buckles or metal shackles?

 

By the way, if you need more selections of release buckle and plastic buckle, I recommend that you can visit the website of SHIN FANG and DYI ER KANG. Both of them are professional plastic buckle manufacturers in the industry. Try to check out their website to obtain ideal bag accessories you need.

Save Your Company Money With Energy Efficient Motors….But You Need To Plan Ahead!

 

Choosing the Right Motor Requires A Plan

 

When a motor goes bad, you rarely have time to consider all the options that you should consider before purchasing a new motor. You likely are in a position that requires immediate action.

 

With a little bit of planning, you could create a long term motor replacement plan that will identify the best, most energy efficient motor for replacement.

 

You Have To Inventory What You Have

 

Survey your motors. Gather nameplate information and obtain field measurements (voltage, amperage, power factor, operating speed) under typical operating conditions. Initially focus on motors that exceed minimum size and operating duration criteria.

 

The initial criteria typical selection criteria include:

 

  • Three-phase NEMA design B motor
  • Non-specialty motor
  • 10 to 600 hp
  • At least 2000 hours per year of operation
  • Constant load (not intermittent, cyclic, or fluctuating)
  • Older or rewound standard efficiency motors
  • Easily accessible
  • Has a readable nameplate.

 

Conduct a motor replacement analysis. You can do this yourself with software at the US Department of Energy MotorMaster+ Software program.

 

After you analyze your facility, you can create your motor replacement strategy with the following 3 three categories:

 

  1. Replace NOW

 

Motors Offering Rapid Payback through Energy Savings, Improved Reliability, or Utility Rebates.

 

These include motors that run continuously (typically 8000 or more hours a year), are currently inefficient (including oversized motors), must be reliable, or are covered by attractive utility rebate programs.

 

Order an efficient replacement motor soon and install it at the next available opportunity, such as during a scheduled downtime.

 

  1. Replace WHEN it fails

 

Motors with Intermediate Payback. When these motors fail, you will want to replace them with an energy-efficient model.

 

Now is the time to contact motor dealers to review the efficiency and prices of available motors. After identifying the most cost-effective replacement model, you must decide whether to purchase it and keep it on hand as a spare, or wait to purchase it until the existing motor fails.

 

This choice depends on how quickly an energy-efficient motor can be obtained through suppliers, how quickly a failed motor must be replaced, and how many motors of the same size and type are used in your facility.

 

  1. Don’t Replace, Leave AS IS

 

Motors with Extended Payback. These motors are already reasonably efficient or are used less than 2000 hours each year. They can be rewound or replaced with a similar motor.

 

Motors and Drives Last A Long Time, Don’t Forget To Review

 

Motors and drive systems have a long useful life. The cost of running a motor may increase significantly in the future.

 

Energy efficiency improvements that are not justified today may become worthwhile in a few years, so periodically reevaluate paybacks and reliability. It is also important to operate your motor efficiently.

 

Other Factors To Consider To Maintain Reliability and Longevity

 

Want to maximize the life of your motors? Here are 2 questions for you to consider:

 

  • How Is Your Facility Power Quality?

 

Address power quality problems. To improve motor reliability and efficiency, it is important to maintain the correct voltage and phase balance, identify and eliminate current leaks, and prevent harmonics in the electrical supply.

 

It is a good idea to have an electrical motor specialist review the electrical system periodically, especially before installing a new motor or after making changes to the system and its loads. Consult the manufacturer before installing any motor under conditions of poor power quality.

 

  • Do You Schedule Periodic Maintenance?

 

It is important to maintain motors according to manufacturers’ instructions. Although energy-efficient motors with higher temperature-rated insulation may be able to handle higher temperatures and other abuse, there is no reason to reduce maintenance.

 

Motors should have good ventilation and be periodically inspected for increased vibration or power supply problems.
