07 JulTips of Bonded Seals

Bonded Seals are also known as Dowty Seals or Dowty Bonded Washers. They are high pressure seals which are used in the Mechanical, Hydraulic and Pneumatic sectors.

 

Bonded Seals were originally designed to replace copper-type washers that are used in high-pressure systems. They comprise of a metal washer and an elastomeric ring which is bonded inside the diameter. The metal washer prevents over-compression and limits deformation of the elastomeric ring.

 

Characteristics:

  • Ideal Pressure Gasket.
  • Reliable sealing at high & low pressure.
  • High & low temperature capability.
  • Reduced bolt torque with no loss of tightening loads.
  • Metal ring prevents rubber compression.

 

The most common washer types are Mild Steel or Stainless steel. Other more unusual metals can be supplied. Different combinations of metal washer and rubber sealing elements can be produced.

 

Bonded Seals are available in a choice of materials including:

  • Mild Steel
  • Nitrile
  • Stainless Steel
  • Viton
  • Brass
  • EPDM
  • Aluminum
  • Silicone

06 JulAbout the Relief Valves

The popularity and importance of the valve are known to us. Actually, it does great favors to industrial process and daily life. A relief valve is particularly used to control or to limit the pressure in a system or vessel which can build up by a process upset, instrument or equipment failure, or fire. The word “relief” can explain all, I suppose.

 

Generally speaking, the relief valve transforms to be as a path of least resistance when the set pressure is exceeded. It is forced to open to divert the fluid flow through the auxiliary route. For the fluid, it would be liquid, gas or liquid-gas mixture. When the fluid is diverted, the set pressure would drop to a normal level, while the relief valve closes at that moment. Take the high-pressure gas systems for example. The outlet of the relief valve is the open air which is connected to the piping. At this situation, it means that set pressure is lower that the relief valve and the relief valve only works with an area which is much smaller than that of the openings area of the valve. In some other cases, it is used to return all or part of the fluid discharged by a pump or gas compressor back to either a storage reservoir or the inlet of the pump or gas compressor. By doing this can protect the pump or the compressor and any associated equipment from excessive pressure. What else, it is employed to open at a predetermined low pressure limit and to admit air or an inert gas into the equipment so as control the amount of vacuum.

 

While putting into practical use, there are various specific kinds. They are pressure relief valve, safety valve, safety relief valve, pilot-operated relief valve, low pressure safety valve, vacuum pressure safety valve and low and vacuum pressure safety valve. They are popular in their specified fields holding their own specifications. With the advancing modern industry, it would be employed in much more fields in the future.

 

Like the Safety Relief Valve is a type of valve which is used to control or limit the pressure in a system which might be built up by a process upset, equipment failure or even fire. A safety relief valve can be installed in a system to protect this system from being subjected to pressures that exceed their pressure limits which might causes system failure and also significant losses. The safety relief valve is designed to open at a set pressure. When pressure within the system is above your set of pressure, it will push the disc to open which allows pressure (fluid or gases) to divert into an auxiliary route out of system.

05 JulSome Tips of Ductile Iron

Ductile iron also referred to as nodular iron or spheroidal graphite iron was patented in 1948. After a decade of intensive development work in the 1950s, ductile iron had a phenomenal nine-fold increase in use as an engineering material during the 1960s, and the rapid increase in commercial application continues today.

 

An unusual combination of properties is obtained in ductile iron because the graphite occurs as spheroids rather than as individual flakes as in gray iron. This mode of solidification is obtained by adding a very small, but specific, amount of Mg to molten iron of a proper composition. The base iron is severely restricted in the allowable contents of certain minor elements that can interfere with the graphite spheroid formation. The added Mg reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed. Control procedures have been developed to make the processing of ductile iron dependable.

 

The high C and Si content of ductile iron provide the casting process advantages, but the graphite spheroids have only a nominal influence on the mechanical properties of the metal. Ductile iron, like malleable iron, exhibits a linear stress strain relation, a considerable range of yield strengths and, as its name implies, ductility. Castings are made in a wide range of sizes with sections that can be either very thin or very thick.

 

Much of the annual production of ductile iron is in the form of ductile iron pipe, used for water and sewer lines. It competes with polymeric materials such as PVC, HDPE, LDPE and polypropylene, which are all much lighter than steel or ductile iron; being more flexible, these require protection from physical damage.

 

Ductile iron is specifically useful in many automotive components, where strength needs surpass that of aluminum but do not necessarily require steel. Other major industrial applications include off-highway diesel trucks, Class 8 trucks, agricultural tractors, and oil well pumps. In wind power industry nodular cast iron is used for hubs and structural parts like machine frames. Nodular cast iron is suitable for large and complex shapes and high (fatigue) loads.

 

Cheng Feng has been producing Ductile Cast Iron (Ductile Iron) for over thirty years. Ductile iron, iron casting, and ductile cast iron are specifically useful in automotive components, and for architectural and engineering solution. Iron casting services are also provided.

04 JulThe Basics of Cosmetic Tattoos and Permanent Makeup Pigments

Permanent makeup (cosmetic tattoos) is often misunderstood by the general public. Many people believe permanent makeup is like getting a regular tattoo. There are similarities, but also important differences. Always consult a trained practitioner who communicates honestly about the risks and listens. Below is some information to help you to make an educated decision.

 

What is permanent makeup?

 

Permanent makeup is the placement of a pigment (solid particles of color) below the skin to create the impression of cosmetics. The pigment is placed in the skin with a needle.

 

Why are cosmetic tattoos different?

 

Essentially permanent makeup is a tattoo, but has a different goal than traditional tattooing. Permanent makeup artist Liza Sims Lawrence, founder of Wake Up With Makeup, LLC in Anchorage explains, “the goal is to be subtle rather than to draw attention.” The artist strives to harmonize with the facial features and skin tones.

 

What are pigments?

 

According to the article “From the Dirt to the Skin-A Study of Pigments” by Elizabeth Finch-Howell “The Dry Color Manufacturers Association (DCMA) defines a pigment as a colored, black, white, or fluorescent particulate organic or inorganic solid, which is usually insoluble in, and essentially physically and chemically unaffected by, the vehicle or substrate into which it is incorporated.” The vehicle, which can be distilled water or other appropriate liquids combined with an antibacterial ingredient such as ethol alcohol, must keep the pigment evenly distributed throughout the mixture.

 

What ingredients are in pigments?

 

Permanent makeup pigments always contain basic ingredients used by all manufacturers. A small number of pigments are created with iron oxides. According to Elizabeth Finch-Howell “iron is the most stable of all the elements and inorganic iron oxide pigments are non-toxic, stable, lightfast and have a range of colors.” Lightfast means the pigments retain their original hue over time. The difference in pigments is generally associated with the vehicle, or liquid, used to place the pigment under the skin. “I use distilled water and ethol alcohol,” states Finch-Howell, “I do not use glycerin as some other manufacturers do because it doesn’t evaporate.” “Glycerin is a humectant with an extremely large molecule,” continues Finch-Howell, “this molecule is literally punched into the skin.” Glycerin is also found in a variety of quality grades. Other permanent makeup practitioners prefer pigments with glycerin because they glide on the skin and do not dry out in the cup. Pigments do not contain mercury, talc or carbon.

 

What regulations apply to the permanent makeup field?

 

The Federal Food, Drug and Cosmetic Act does not regulate pigments. However the FDA requires all color additives to be screened and approved by the US Food and Drug Administration prior to being sold. Elizabeth Finch-Howell states, “There is a list of FDA approved color additives for food, drugs, and cosmetics [that] pigment vendors should be drawing from to formulate their pigments”. “All organic colorants are subject to batch certification by the Color Certification Branch of the FDA,” Finch-Howell continues, “of the approximately 90 pigments on the FDA approved color additive list, and all inorganic colorants listed are exempt from certification.”

 

Do allergic reactions or side effects occur?

 

I have never had a client suffer allergic reactions to permanent makeup. According to Liza Sims Lawrence, authorized distributor of LI Pigments, “photo sensitivity reactions (sunlight) may sometimes be revealed by slight itching and raised, but this is normally associated with reds and violets used in body art tattooing.” Sims Lawrence continues, “Once the area is no longer exposed to intense sunlight, the itching and raising usually dissipates. In permanent cosmetics we do not often use body art reds and violets on the face. True allergic reactions are extremely rare.” Permanent makeup has been known to cause itching and burning during an MRI. However, the FDA states, “This seems to occur only rarely and apparently without lasting effects.” It is best to inform the doctor and MRI technician that you have permanent makeup

 

What is the difference between organic and inorganic pigments?

 

Organic pigments are made from plant matter and inorganic pigments are made from dirt, as are topical cosmetics. In permanent makeup, organic and inorganic pigments both play important roles; pigments are not labeled organic in the same way food is by the government. Organic based pigments are necessary for vibrancy of color. Inorganic pigments give us earth tones and are lightfast. According to Elizabeth Finch-Howell, her pigment company, Derma International, uses inorganic and organic pigments and has been operating for 17 years without a single allergic reaction ever reported.

 

Permanent makeup is an amazing opportunity for men and women to make their lives easier and to love the way they look every day, but there are many misconceptions. Talk to a professional, ask questions and review references.

 

Founded in the 1983, BELLA is now of the leading manufacturer of permanent makeup pigments, eyelash perm and accessories. Over the years we have grown rapidly into global market. BELLA products have been sold all over the world. We will be continued to provide the latest technology and products to our partners and dedicated to lead the trend of market.

29 JunTypes and Advantages of Pneumatic Tools

The mechanical equipment that uses compressed air or gas to operate is known as pneumatic tools. These tools are also known as air pressure tools. The air pressure tools are used for various purposes. These tools are efficient and save time and energy but require special handling and care during usage.

 

Different Types and Uses of Pneumatic Tools

 

There are various types of air pressure instruments available in the markets today. Some of the most common types of tools include: paint sprayers, nail guns, staple guns, drills, grinders, buffers, sanders and wrenches, chipping hammers, jackhammers, reverting guns and so forth. There are many other types of air powered equipment used for different purposes.

 

Pneumatic tools can be used for a number of purposes such as:

 

  • Nail guns: the nail guns are also known as the air hammer or the power nailer. These guns are much more efficient and powerful than hammering the nails manually. These air hammers or nail guns are also used for several other purposes like cutting, scrapping and chipping.

 

  • Blow guns: these guns are ideal for blowing dirt and dust away from surfaces.

 

  • Air sanders: the air sanders are useful in removing paint and rust and efficient in automotive work.

 

  • Caulking guns: these guns produce uniform bead to apply to surfaces in a quick pace.

 

  • Air staplers: stapling can be done quickly and efficiently with the air staplers.

 

The tapping machines and the air drills make use of the compressed air in the pneumatic tool for efficient functioning. The air impact wrenches, the sanders and the air ratchets are also air pressure tools that use the compressed air for powerful functioning. The air impact wrench is ideal for removing or tightening bolts.

 

Basic Advantages of Using Air Powered Tools

 

There are many advantages of using these pneumatic tools and some of them are:

 

  • Greater efficiency: Unlike the manually operated tools, the air powered tools are much more efficient and powerful.

 

  • Weighs less: These tools weigh less as the power is transferred through the air compressor. Therefore the use of these tools is much easier.

 

  • No electric power required: As the pneumatic tools are powered by an air compressor it does not require electricity unlike the other tools.

 

  • Productivity: As these tools are efficient, it requires lesser time and thus improves productivity.

 

  • Easy to work: with the help of the air powered tools, it is easier to work and involves less labour.

 

The uses of pneumatic equipment involve certain safety measures. It is important to wear safety gear while working with these tools. Regular cleaning and maintenance of these tools are essential for safe and efficient functioning of the tools.

 

Most of these tools are powered by air compressors which are connected to the tools with a hose. These hoses should be resistant to rust and it should be strong. These hoses should be cleaned thoroughly before operating the tools. Most of these tools can be bought online from the pneumatic tools manufacturers listed in the business portals. There are a number of suppliers who sell superior quality tools at affordable rates.

You will also not just go out to buy any type of power supply; there are a few things that you will want to take into consideration. This is why you need to do your research on switching power supply efficiency.

 

You will find that there are quite a few different brands of power supplies out there. You will also find that there are a few different types of units that do different things. Most people do not know this, but a generator can also be known as a power supply, because it is a device that supplies power to other devices that needs it.

 

A power supply is not just a device that provides power at a lower output than your normal home output. Yes, we all know that, traditionally, this unit is plugged into a normal wall socket, take in the power and outputs that power at a lower amperage or voltage. However, if you were to look at it you would find that it is still providing power, which means that anything that provides power can be called a power supply, especially if that device is providing that power when you do not have any other source of power, and when you need to be switching power supply efficiency.

 

If you are looking for this unit you need to know that it is best if you started your search online. The internet holds a ton of sites that offers information that will lead you in the right direction. You need to know what you need to get out of your unit.

 

This means that, if you are trying to power up your home, you will need to know the exact amount of power you will need your unit to output. This means that you will need to find out the usage for each of the devices you need to power up. If you are going to power up your TV, refrigerator, deep freezer, computer, stove, if you have an electric stove, and a few of the lights in your home, you need to know that you will need an output of X from your supply unit or generator in order to keep your home running for a certain amount of time.

 

You will also need to know that a computer will need one of these units of it own. This is because you will need a constant flow of power to a device this sensitive. There are a number of computer UPS’s out there.

 

Switching power supply efficiency will let you change the output of the power you get out of your device, so make sure that you get one that offers this tool, because it will always come in handy if you are powering up different things all the time.

17 JunPallet Truck or Forklift?

The pallet, although essentially a basic item, has nevertheless generated widespread demand throughout many markets and industries a like – regardless of size, whether it includes multinational company or a little shop corner, it provides a great purpose to ensure that the economy runs efficiently, but importantly, effectively. Demand for this commodity is consequently certain to continue as long as there is always a market for selling and buying.

 

Like any product that has a high demand, various companies will consequently try and take advantage of this situation by acquiring a reputation within the market to outperform rival businesses who want to benefit from the share of available revenue. Therefore, to ensure this happens, various pricing strategies can be applied, but this approach will only be successful to an extent, especially when the other companies will try to implement similar techniques. As a result, it will be imperative to diversify into more product areas, such as the function that moves pallets, the pallet truck or its closet relative, the forklift.

 

Ideally, the forklift acts as a useful machine suitable for moving heavy items quickly and effectively – a highly desirable machine for use within the large industrial factory floor which require great distances to be covered. However, despite clear advantages and plus points for using a forklift, many organizations have not got the capacity or ability to fund such machines; therefore it will be necessary to consider another approach for the extensive array of companies.

 

Primarily, the central concern is the amount of traffic that can occur as a result of forklifts navigating in and out of the buildings – depending on site/building size, the extent of traffic flow will clearly vary and consequently affect the quality and timing of work. In contrast, due to the nimble nature of the pallet truck, traffic will be significantly reduced for all organizations both large and small. For a large organization, usually, speed is of the essence and many will argue that this will restrict work, however a solution to this dilemma is to integrate a unified approach which uses both the pallet trucks and forklifts – essentially, the pallet truck will focus on those smaller tasks that would usually waste time to complete the larger loads. A simple, yet effective time management strategy for any organization to plan and affect.

 

The main factor that will usually dominate the decision making within any business is money and associated costing. As mentioned within the previous paragraph, the distribution of work will need to be assigned accordingly to its effectiveness for the company – so for example, buy the required amount of forklifts to assist work to accompany those people delivering work via pallet trucks.

 

Although you cannot acquire complete organizational efficiency, by reviewing your daily deliveries and timeframes work is usually completed in, this can act as a useful way to pinpoint areas of improvement and whether a forklift will actually benefit the costing structure of the company. Because remember an idle truck which isn’t being used, or sitting unable to move as a result of the extensive traffic will not improve matters. The pallet truck’s place in industry is certainly important.

 

By incorporating the use of certain vehicles into your industrial workplace, they can help further your operational capacity depending on your requirements. Although simple, pallets can be regarded as an essential item, but its speed of transportation can impact delivery schedules so strategically decide whether it’s a pallet truck or forklift?

 

Noveltek is a well-known and proven pallet truck manufacturer. Noveltek promises to provide customer with higher value material handling equipment for electric pallet truck, powered pallet truck, reach truck, hand pallet truck, order picker truck etc. The material handling equipment has been recognized worldwide for design excellence and innovation.

25 MayAbout Orbital Air Sander

For any sanding or polishing jobs that require an excellent finish, on almost any surface, an orbital air sander is the tool that you need. Orbital sanders have quickly become the tool of choice for anyone wanting to either prepare a surface for painting, or alternatively, to get a superb finish afterwards.

 

An orbital air sander is a flexible and easy to use air tool, which is considered essential for professional auto body repair jobs, and is also the kind of equipment that every hobbyist will want to have in their toolkit in order to ensure that they can do a great job.

 

An orbital air sander features a sanding pad that moves in a random manner around a specific center point. It is this random movement that is the key to the success of the air tool. Rather than with traditional sanding devices such as a belt sander, where the tool leaves a mark on the surface and can lead to an uneven finish, with a random orbital air sander, the finish is even over a much wider area, meaning that the finish that you can expect is much better and smoother.

 

The combination of a circular and random action of the sanding disc on an orbital air sander means that it is able to sand in any direction, cover a larger area relatively quickly, and avoid concentrating too much sanding action on one area. This means that the finish will be more even than with a belt sander or even old style orbital devices that did not have a random aspect to their movement.

 

You can add different sanding discs to an orbital air sander to ensure that it is properly set up for a huge variety of different jobs. From heavy duty sanding paper for tough jobs through to buffing cloths in order to get a final polished finish at the end of the job. With most orbital air sanders, changing the disc takes just a few seconds, allowing you to get a variety of jobs done a lot quicker.

 

Perhaps the most immediately obvious application that an orbital air sander can be used for is in preparing an area of auto body for painting. You would start off with a fairly rough grade of abrasive paper in order to strip back the paint and leave bare metal. Within a couple of seconds, it is possible to change to a finer abrasive in order to smooth the metal out and get it ready for paint. After each coat of paint, an even finer abrasive can be used in order to get a great finish, before the disc on the orbital air sander is changed for the final time and replaced with a buffing cloth to get the perfect finish.

 

Pretty much every power tool manufacturer produces their own version of the orbital air sander, and they range in price from basic inexpensive models that are useful for anyone wanting to do small jobs around the house right up to high quality professional air tools that are designed for the professional auto body shop, and will provide reliable service for years.
