How Do You Choose an O Ring?

On January 19, 2018, in Industrial Supply, Manufacturer, Oil Seals, by Jasmie K.

When installing a pressure sensor, especially on units with parallel threads, such as BSP, UNF etc, it is necessary to use an O ring on the external face of the hexagon mounting face to ensure complete sealing.


It is important to choose the right sealing gasket to give long-life performance. Several factors must be taken into consideration when you choose an O ring, including compatibility with the fluid under test, the temperature range of the application, mounting torque, size, pressure ranges etc.


There are many types of seals on the market, from gaskets in copper, lead, Viton, nitrile, Teflon etc. The following are some of the more commonly used seals.


Viton O Rings

Viton O rings are oil resistant and are capable of operating in temperatures between -15 and +200°C.


Teflon O Rings

Teflon O rings have similar properties to Viton, but are used for pressure ranges above 500bar (7000psi).


Dowty Bonded O Rings

Dowty bonded O rings are versatile but relatively expensive. They comprise a metal annulus to which a medium nitrile elastomeric ring of trapezoidal section is bonded. Dowty bonded O rings are commonly used with hydraulic fluids or mineral-based engine lubricating oils. Temperature range is -30 to +110°C, and maximum pressure is 1500bar.


Nitrile O Rings

Versatile and economical, nitrile O rings are suitable for temperatures from -40 to +110°C, and are resistant to mineral hydraulic oils, greases and certain chemicals. Nitrile O rings are available in imperial and metric sizes.


In addition there are now many different adapter ranges available that have built-in seals. Alternatively there is the option of choosing a thread that self-seals or has a cone sealing arrangement, such as Swagelock, -3 fitting etc.

A gearbox is a way to increase or decrease torque, motor speed, and direction. What are the differences between gearbox types? Well, determining which kind of gear motor is most suitable for you will depend on the application you are doing. Every kind of gearbox has its own advantages and disadvantages. For further details, keep reading below for descriptions of the most common gear motors and their pros and cons.


Planetary Gears:


This gear design mimics the planetary rotation, hence the name. Planetary gear motors consist of 1-6 outer spur gears that rotate around a central gear, which is also referred to as the sun gear, and the outer gear, also known as the planet carrier.


This type of gear is compact, highly efficient, emits little noise, and provides excellent torque transmission.



  • Huge Torque Capability
  • Good Load Distribution
  • Handles Extremely Large Reductions
  • Small Size
  • High Efficiency
  • Ease Of Maintenance
  • Generally More Complex
  • High Stress On The Output Shaft Bearings
  • Thermal Limitations On Smaller Sizes



Worm Gears:


Worm gears are used in applications where large gear reductions, torque, and braking are necessary. Some of the more favorable features of worm drives are that they achieve high ratios in a single reduction, ability to handle shock loads and low noise.


One advantage that makes worm drives desirable over other gearboxes is that they have relatively few moving parts in high reduction ratios, simply two shafts – input and output – supported by four bearings.




  • Ease Of Maintenance
  • Low Noise Properties
  • Handles Large Reductions
  • Large Shock Load Capability
  • High Thermal Capacity
  • Moderate Efficiency
  • Large Package In Design
  • Relatively Expensive To Manufacture


Spur Gears:


Spur gears are the most common type of gear. These are used in the simplest of gearbox designs, making them the cheapest and most common to manufacture. Spur gears are straight cut gears that have teeth that is meshed with other spur gears to form the gearbox. This design allows the gears to decrease speed and increase torque.


While spur gears are inexpensive and common, they aren’t always the best solution, especially in cases where high torque or speed is needed. Several spur gears are needed to make large reductions. They can be very loud while in operation, and if too much stress or force is put on the gears they can easily break.




  • Inexpensive To Manufacture
  • Easy To Operate
  • Efficient And Reliable At Low Speeds
  • Require Several Gears For Large Reductions
  • Loud At High Rotational Speeds
  • Not Able To Handle Large Amounts Of Torque


Helical Gears:


Helical gears are similar to spur gears in that they are inexpensive to manufacture but have a few differences that give them an advantage. The teeth in helical gears are cut at a ‘helix’ angle to the leading edge of the gear so the gears to mesh together over the length of the helical cut. This allows for a smoother transfer of torque. Helical gears also make less noise than spur gears do.




  • Inexpensive To Manufacture
  • Easy To Operate
  • Good Torque Capacity
  • Less Noise While Operating
  • Requires Several Gears For Large Reductions
  • Higher Maintenance Costs

Advantages of Zinc Alloy Die Casting

On January 15, 2018, in Manufacturer, by Jasmie K.

If you’re considering aluminum die casting, there are several reasons why Zinc die casting could be a better option for you.


10 X’s Greater Tool Life

A Zinc die’s tooling life can be more than 10 times longer than that of an aluminum die! Lower casting temperatures for zinc are easier on tools because they create minimal thermal shock and prolong die casting tool life. With dies costing upwards of $50,000 each, having a long lasting tool can represent a significant cost savings.


Superior Thermal Conductivity

Zinc is a better conductor of heat than Aluminum which makes it perfect for applications like heat sinks or electrical components. This means Zinc is able to absorb and dissipate the heat better than Aluminum.


Low Melting Point = Cost Savings

Zinc melts at 787.2°F whereas Aluminum melts at 1,221°F. This gives Zinc an advantage because casting can use a process called “Hot Chamber” casting which is quicker as well as being less costly than “Cold Chamber” methods.


Faster Cycle Times = Better Pricing

Using the Hot Chamber process also gives Zinc a major advantage over Aluminum because the hot chamber process goes so much quicker than Cold Chamber. In cold chamber, Aluminum needs to be manually poured into the die either by hand or using a robot. Using hot chamber casting, the molten liquid zinc is shot into the die using a highly pressurized “plunger” which systematically shoots the zinc through the die.


Thinner Wall Stock

ZAMAK alloys have exceptional casting fluidity. It’s possible to cast walls in ZAMAK as thin as .25 inches. Thinner, stronger walls results in smaller and lighter products with lower costs.


Less Machining Required For Tight Tolerances

Zinc die casting has tighter tolerances than Aluminum or plastic die casting, which often eliminates the need for additional machining. When no additional machining is needed, it’s called “Zero Machining” manufacturing. This is one of the major advantages of Zinc die casting.


Superior for Decorative Finishing

ZAMAK alloys have a better surface for finishing because Zinc comes out of casting with a smoother skin. Because Aluminum has to be so much hotter than Zinc, the thermal shock from being put in a die produces a part with a surface that can be more pitted. Chrome finish amplifies every defect in a part, which makes Zinc much easier to finish compared to Aluminum. Zinc die casting parts can be easily polished, plated, painted, chromated or anodized.


Tough Durability

Zinc alloys are some of the strongest and toughest materials for die casting. Neither plastic, gray cast iron, nor Aluminum withstands impacts as well as Zinc alloys do.


If You Do Choose Aluminum

Sometime aluminum is the best choice. To learn more about aluminium die casting process or zinc alloy die casting, please visit Champion H&C Inc.

Determining the ideal aisle width for your application means you need to look at a lot of factors. Is Very Narrow Aisle, or VNA, right for your warehouse? In this article, I am going to go over the advantages and disadvantages of VNA truck design, and when you would use it.


First of all, Very Narrow Aisle is defined as less than 6 feet between the racks, and is usually used with selective pallet rack. Often, guidance systems like guide rail or wire is used to keep the trucks on track. The main component that decides your aisle width is your lift truck. If you are doing VNA, you will need a special forklift to navigate the aisles, you can’t use a standard forklift. VNA trucks (turret trucks) usually only turn the load instead of the whole vehicle, and isn’t dock working trucks.


Will VNA Trucks Work For You?

NA2.0 VNA Truck


  • Improves space, you can store 40%-50% more inventory
  • Good for applications with less than pallet storage
  • High productivity in full pallet retrieval



  • Requires a certain lift truck which is more expensive
  • Two vehicles cannot pass at the same time
  • Lower flexibility, you usually have to store the same SKU
  • Requires a “hand-off” of inventory from the VNA forklift to a dock working forklift on outbound, and the opposite for inbound


If the pros outweigh the cons, then utilizing Very Narrow Aisle would be beneficial to your warehouse.


Need more VNA Trucks information, try to visit the well-known forklift truck manufacturerTailift Material Handling Taiwan Co., Ltd. The company provides kinds of material handling equipment, including counterbalance trucks, electric pallet truck, electric towing tractor, VNA trucks, and much more electric forklift trucks.

Stainless steel, a rust-resistant variation of ordinary steel, comes in many standard types, each identified by a number. Two, known as 430 and 304, have different properties that come from mixtures of iron and other metals in slightly different amounts. Both types have many practical industrial, medical and household applications.


Metals and Alloys

Stainless steel is an alloy, or combination of two or more metals, that has beneficial features not found in any of the metals by themselves. To make stainless steel, chromium is added to ordinary steel, giving it corrosion-resistant properties. Type stainless steel 430 is made up of 17 percent chromium and 0.12 percent carbon while stainless steel 304 contains 18 percent chromium and 0.08 percent carbon.


Magnetism, Cost and Physical Features

Raw iron is ferromagnetic, meaning you can attract it with a magnet, and you can make a magnet from it. The 430 grade stainless steel is also ferromagnetic. However, 304 is not. Type 430 steel is less expensive and is somewhat difficult to form and weld than type 304.


How They Are Used

Type stainless steel 430 is ideal for the production of automotive trim, the insides of clothes dryers and dishwashers. Manufacturers use stainless steel 304 in the production of kitchen sinks, counter tops, food processing equipment and other equipment regularly exposed to corrosive environments. Type 430 is one of the most popular grades of stainless steel.


If you have any interest in stainless steel 430 manufacturer, I recommend that you can visit the website of STANCH. The company can provide kinds of stainless steel products including stainless steel coils, stainless steel strips, stainless steel plates and more.

When it comes to waking up with the perfect eyebrows to envy all others, there are two techniques that are used in the industry; traditional Permanent Makeup and Microblading. But what’s the difference between the two techniques and what fabulous results can each treatment offer? Read more below:


Permanent Makeup

Permanent makeup is the most common phrase used but terms such as Micropigmentation and permanent cosmetics are also used to describe the same procedure. For permanent eyebrows, as well as lip and eyeliner treatments, a cosmetic tattooing machine is used to gently implant pigment into the skin using a variety of fine needles. It’s different from a regular tattoo machine in that the frequency is much lower meaning the pigment is implanted closer to the surface. Some would say the sensation feels like an electric toothbrush pressed against the skin; a little uncomfortable but not too painful.


There are a variety of looks you can opt for when choosing your permanent makeup treatments. If it’s a dramatic powder brow you are looking for to mimic the look of makeup, you’ve got it. If it’s more realistic brows you’re looking for go for a procedure using individual strokes to create your desired brow shape, go for it. You can also opt for bright lips, natural lip blush, subtle lash enhancement or feline Latino eyeliner flicks – the choice is yours!


K.B Pro Brows: Microblading

Microblading is a slightly different technique that’s still firmly in the tattooing family, meaning pigment is implanted into the skin, but a precision hand tool is used instead of a machine. The beauty of microblading is that the hair-like strokes you can achieve are so fine that it’s the most hyper-realistic treatment yet, it’s no wonder that it’s often referred to as ‘eyebrow embroidery’.


A microblading technician meticulously draws each hair stroke onto the skin to follow the direction and length of the existing hairs. If there are no hairs present, not to worry, a skilled technician can create beautiful brows that suit your face shape and mimic that of a natural brow. The channels created by the microblading technique are closer to the surface then when using a machine and the needles used are even sharper, meaning even more precise and finer hair strokes can be created. If you want the most natural looking treatment that no one could ever guess you’ve had, this is ‘the’ treatment to go for.

When looking for fastening solutions, one common solution to use for routinely maintained products is self tap screws.


What Is A Self Tapping Screw?


Self tapping screws are fasteners that are designed to drill their own hole as they are screwed into wood, plastic or metal. By using a screw driver and self-tapping screws, precisely fitted threads are created. Self tap screws are ideal for items that require regular maintenance and work well when working with two different kinds of material being fastened together.


These screws either come with a blunt, flat, sharp or piercing tip. Sharp-tipped self tapping screws drill their own holes in softer wood and plastic. However, it is helpful to drill a pilot hole when working with harder material. When drilling a pilot hole, make sure to use a smaller bit than the screw so it may still serve its purpose.


What material is involved can help determine what type of self tap screw will work best. There are two types: thread-forming and thread-cutting. Thread-forming screws are usually used when working with plastics. Thread-forming screws are designed to stay in place tightly, but over tightening the screw could result in materials breaking under too much pressure. Thread-cutting screws are used mostly when working with metal and wood. One drawback to using thread-cutting screws is that the threads may strip if the application is disassembled. This prevents reuse of the fastener and requires a new, slightly larger self tapping screw when it is time to reassemble.


However, there is a solution to prevent stripping. A metal insert can be installed from the beginning that would allow the self tapping screw to be regularly fastened and unfastened. These metal inserts also work to help minimize stress and expand as the fastener is screwed in.


Just like other types of fasteners, self tapping screws are available in all shapes and sizes and are also available in numerous different head types. When choosing the right self-tapping screw for any given application, it is important to consider the length of the screw tip. In order for the screws to serve their purpose and work properly, the screw must be drilled fully into the material before threading can begin.


Although self tapping screws are typically more in terms of price, they can help cut down on time and labor costs and combine the steps of drilling and fastening.

Shutting off utilities such as your home’s water supply or electrical power is fairly common—something you do whenever making a repair or upgrade. Shutting off your natural gas supply is not something that occurs very often, but there are still times you may need to shut off the gas supply in your home. Knowing how to do this is important, because when it’s necessary, it may need to be done in a hurry.


Reasons for Shutting Off the Gas

The main shutoff valve controlling you home’s natural gas supply may come into play during major construction or renovation involving gas lines, when closing up or shuttering a home, to prevent possible flood damage. Or, in rare instances, you may need to shut off the gas valve when a gas leak is suspected inside the home.


Once the valve is turned off, however, do not turn it back on by yourself. It must be turned on by a qualified person such as a gas company service technician or a licensed plumber. To be a “qualified person,” you must be able to confirm proper operation of all pilot lights and gas appliances once the gas valve is turned back on.


Location of the Main Shutoff Valve

The main gas shutoff valve is located next to the natural gas meter supplied by your utility company. Your gas meter may be located outside your home on an exterior wall, or it may be found inside your home on an outside wall—often in a basement or utility area, such as a garage or the mechanical room where the furnace or water heater are located.


How to Shut Off the Main Gas Valve

The main gas shut off valve is a large valve located next to the natural gas meter. If the valve handle is parallel to the gas pipe, then the gas supply valve is open and the gas is on.


  1. To close the valve, use a clamping plier, an adjustable wrench, or an open-end wrench, and turn the valve handle 90 degrees so it is fully perpendicular to the gas line. It is a good idea to keep a wrench handy for this purpose and keep it located next to the shutoff valve.


NOTE: Many natural gas meter valves provided by a utility company have a hole in the handle that will line up with a corresponding hole in the valve body when the gas valve is in the closed position. The utility company will use the hole to lock and/ or seal the valve in a closed position when the gas account is closed. When the holes in the valve handle are lined up, it indicates the valve is in the OFF position.


  1. To ensure sure the gas shutoff valve is, in fact, fully closed, note the dial numbers on the meter face and write them down. Then check back in about 10 minutes. If the numbers have not changed, then you know that the shutoff valve is fully closed.


If you want to gain more information about shut off valves, I recommend that you can visit Alpha Brass Controls: Their on / off valves are manufactured from the best quality Brass and verified and tested under the highest quality standards. All Alpha Brass Controls valves are 100% MIT and 100% leakage tested to ensure the standards of quality and safety. More details, try to send inquiry to them.
