Product identification plays an extremely important role in communicating a product’s position and brand in the marketplace. Plastic nameplates can convey messages, brand, classifications, description, schematics, warnings, instructions and many other types of product information.

Plastic injection molded nameplates help to identify your products and help them stand out in the crowd. Before we go further, let’s take a quick look at the plastic injection molding process.

The Plastic Injection Molding Process

The plastic injection molding process is not a complicated one. Molding processes of this sort involving metals go back many years, and basic principles have not changed, just the methods and materials.

Of course, you have seen what the finished product looks are. You’ve seen them more times than you may be aware of. You’ve seen them as car emblems, appliance and industrial nameplates, custom plastic nameplates, recreational product nameplates, point-of-purchase, plaques and signs. They fill the world around you, but do you know how are they made?

The process begins with a plastic pellet made of a composite of organic and inorganic polymers, plus additives to aid in the melting process. This small pellet is tossed into a hopper with thousands of other pellets. This begins the journey from pellet to product. The next step is preparing the plastic.

The pellets are released onto the threads of a giant rotating screw. As the pellets travel along, they are heated to melting temperatures, somewhere around 400 degrees Fahrenheit. Of course, the higher quality the plastic is the higher temperature it takes to melt it. The pellets are rolled along the screw because the process also requires friction and force. The screw provides both as the pellets roll along its surface and crash into each other.

Now that all three requirements are met, friction, force and heat, the pellets begin to liquefy and the next step of filling begins. The screw continues to guide the liquid plastic along its threads to a valve. Under high pressure the valve forces the plastic into a custom designed mold – made of heat resistant metals – until every cavity is filled. Once this is achieved the mold goes into the holding phase. The filling and holding phases are crucial steps in the plastic injection molding process. Their execution will determine the quality of the finished product. The metals we use for the mold insure that the last piece made carries the same qualities as the first.

The Next Step

The pressure on the mold is maintained while the molten plastic cools to a solid state. This stage could take a few minutes as the mold absorbs the heat from the melted plastic, and in turn is cooled by coolant that encircles it. While the part is cooling, the screw returns to its original position, collecting more pellets from the hopper. The product is then ejected from the mold and moves to its secondary processes such as decoration, sub assembly, or shipment. The mold closes, and the process begins all over again.

Advantages of the Plastic Injection Molding

There are several important advantages of utilizing injection-molded plastic:

1. The plastic injection molding allows complex and intricate shapes to be manufactured. Shapes that would be too difficult or costly to manufacture with different processes.
2. The plastic injection molding allows for a high volume of plastic nameplates and custom plastic signs to be manufactured at the same time with the same mold and quality.
3. The metal molds have a long life. When you come back for a future order, the mold will be ready and your next order will be identical to your first. In addition, their initial cost is low too.
4. The plastic nameplates can be decorated in a variety of ways such as textures in the mold, metallic foil, ink, UV protection, and more.

Other Advantages

Plastic Injection Molding allows manufacturers to produce custom plastic nameplates and components that would be too costly to make as intricately as required, by utilizing traditional machining methods. Injection-molded plastics also saves you time and money by allowing high numbers of pieces of the component to be made at the same time, with each copy identical to the one before it. This process also reduces labor costs by minimizing the need for manual labor from employees. Finally, there is virtually no wasted material. Any unused or left over plastic can be re-cycled to be reused in the process

Once you have decided that your DIY project is going to require some stainless steel sheet, you basically have three decisions before you, in order to select what you need.

The two most foremost factors in choosing to use stainless steel sheet are its resistance to corrosion and staining. Technically this is not the case. It most certainly can corrode and stain. However, under most commercial and residential applications its strong resistance to corrosion and staining will normally suffice.

The other misconception is to do with what most people call a “sheet”. In the metals industry the rule of thumb is that anything over 3mm thick is no longer called a sheet but is referred to as plate. So if your application calls for anything over 3mm thick, then you are actually looking for stainless steel “plate”, not stainless steel “sheet”.

Step One – Grades

The two most commonly used grades are 304 and 316. Now, 316 stainless steel sheets are to be preferred above 304 stainless steel sheets if your application is in a corrosive environment like salt water for instance. Although, both 304 and 316 suffer pitting and crevice corrosion the 316 grade is notably less.

Grade 316 is also considered “food grade”, and is used where food products are being handled. If you were looking to use a piece of stainless steel sheet as a splash back however, you could save some money and use grade 304 because it would not be coming into actual contact with the food preparation.

Step Two – Thickness

The thickness of a sheet is most commonly between 0.4mm and 2.5mm. Anything thinner than 0.4 would usually be referred to as foil and more than 3mm thick would mean it’s a plate.

Stock standard dimensions of a 0.4mm up to 0.9mm thick sheet would be either 2000mm X 1000mm or 2500mm x 1250mm. Between 0.4mm and 2.5mm you would also usually be able to find a 3000mm X 1500mm available. Having selected the right thickness and grade for your project, you can now have your stainless steel sheet custom cut. Using a guillotine, laser cutter, or waterjet cutting machine you are able to cut some very complex shapes with precision accuracy.

Step Three – Finish

Depending on your application you can decide on what finish you would like the sheet to have. The manufacturing process of these sheets involves them, first being rolled to correct size and thickness, then annealed and pickled and lastly passivated by passing the sheet one last time between some highly polished rollers. This prepares it to accept one of many available finishes and surface patterns.

The most popular finish is the brushed finish. This finish consists of many fine lines or scratches, all running in the same direction. The Satin finish is produced by softly brush-scratching the sheet until a dull sheen is produced. Lastly, the mirror finish which as the name implies creates a highly polished and reflective effect.

In order to protect the surface of your stainless steel sheet, a plastic coating is applied to either one or both sides of the sheet as it passes through the plastic coating machine rollers.

Whether you need a full size stainless steel sheet or a custom-cut for your business or home, you are now better prepared to know what you’re looking for and hence make an informed decision when ordering.

A pressure gauge is a device that measures the pressure of a container or vessel of compressed gas or liquid. Widely used all over the world, pressure gauges fulfill tasks ranging from checking the pressure on car tires to measuring different regulatory systems inside a power plant. Pressure gauges come in any different number of styles, and are designed for a variety of purposes. Like other measuring devices, pressure gauges should be periodically calibrated to confirm they are working properly, especially when they are used for safety purposes.

These gauges can work two different ways. They can measure pressure by comparing air in a vessel, such as a tire, to a complete vacuum. Or they can measure pressure relative to the ambient, or outside, air pressure. In either case the device is usually mechanical, with a moving part inside the gauge that moves in response to pressure changes that push against the moving part to provide measured reading. Some gauges provide digital readouts while others use traditional dials directly linked to the gauge.

The Bourdon tube is one of the most common types of pressure gauge, and is used to measure high pressures. A Bourdon pressure gauge is basically a tube coiled into a spiral shape or helix, or less often formed into a “C” shape, so that the tube will straighten out when the pressure increases.

A Diaphragm is another gauge used to measure more subtle pressure changes. It uses a deflection of a flexible membrane to separate regions under different pressure. This amount of deflection is repeatable for certain, known pressures so calibration can be used to determine the desired pressure. The deformation of a diaphragm depends on the variation in pressure between its two faces. The reference face can be opened to the atmosphere to measure pressure, or alternatively can be sealed against a vacuum to measure absolute pressure. The deformation can be measured using optical, mechanical, or capacitive techniques.

These pressurized systems are found in a large number of places. For example, in just a car the fuel, lubricant, and brake fluids are all pressurized, as well as the air in the tires. Industrial factories use pressurized systems to coordinate any number of control systems that can be almost any shape and size. It is important that workers are able to monitor the pressure in these systems, as they can identify potential safety concerns such as pressure that is dangerously high or dangerously low. Either one can lead to massive system-wide failures and endanger the lives of the people working there.

Certain pressure gauges are linkable to remote indicator panels which are capable of alerting people when a problem develops with the gauge. Modern day vehicles, for example, have pressure gauges placed inside the tires which can alert the driver when there is a problem with tire pressure. This eliminates the need to check the tire pressure by hand. Other gauges are designed to automatically shut a system off if pressure does not fall within an acceptable range. Today pressure gauges are constantly being advanced to increase reliability, efficiency, and safety.

The early years of SKON was focused on general pressure gauges and vacuum pressure gauges. We gradually improved our technology for production and decided to set a new objective for the company to move into the new generation models of SKON pressure gauges with high precisions & calibration.

Grinding machines are used in different industrial setups to grind different materials. A grinding machine is a machine tool and has an abrasive wheel as its main part. The material grinded in the machine is known as work piece. From plastics to variety of metals, different work pieces are grinded in these machines.

Visit a b2b marketplace and you will find various manufacturers offering these machines with different specifications. The variety exists due to the need to cater to different purchasing needs of the customers. Here is a discussion to help you know what features of grinding machine your customers would look for.

Types of Grinding Machines

First of all, you must be familiar with different types of grinding equipment and which of them are most purchased in your region. Here are the main types of machines you should find with suppliers:

• Belt Grinding: Processing of the work piece, including finishing, edge breaking and removal of stock is easily done with this machine.

• Bench Grinding: Hand grinding of cutting tools like lathe tools is done with a bench grinder. Many other rough grinding functions are also performed by it.

• Surface Grinding: As the name suggests, surface grinders work upon the surface of the work piece to lend smoothness. A refined look of the work piece is obtained through the process.

• Jig Grinding Machine: Used for processes that require high level of accuracy and finish, a jig grinder is suitable for grinding complex shapes.

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. If you need more details about safety relief valves or other fittings, welcome to contact Golden Highope Industrial Inc.

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.

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. BELLA will remain to be efficient, responsive, reliable, friendly and professional. To learn more about permanent makeup pigments, welcome to contact us!

Used for holding electronic modules like hard disks, and processors, rackmount chassis are frames that can fit into 19-inch racks. They can also hold visualization walls and I/O cards and can fit in one rack unit or 2 or more shelves.

Different types to fit your needs

Depending on your needs or specifications when it comes to the safety of your electronic modules, you can choose from the following different types of rackmount chassis:

o 1U: This can fit in a single shelf on the rack. They are able to support single and dual processors since they are 1.75 inches high. They also have the lowest chassis profiles.

o 2U: This type can cover 2 shelves on your rack. They are capable of supporting quad processor systems and they also have twice the capacity of the 1U. Their depth is almost 24 inches and they are 3.5 inches high.

o 3U or 4U: If you need 3 to 4 shelves, then the 3U or 4U chassis is for you because they are perfect for cluster applications that require the use of many I/O cards, video cards, and high-speed networks.

Things to consider

Whether it is a 1U, 2U, or a 3U/4U, try to make sure that it is compatibility with your rackmount server. You also need to consider the kind of cluster application that you have before you buy one. Furthermore, choose a chassis that is made of aluminum or steel to ensure resistance to heat and extreme changes in temperature. Remember that a durable chassis can do more for the protection of your electrical modules especially during shipping and handling.
