Welcome to our Plastic Injection Mold & molding manufacturing Company! Here you find information about custom plastic injection mold and molding processes, techniques, and specialised molding technology so that you keep yourself informed with the latest trends and technology.
What is a plastic injection mold?
A Plastic injection mould is a metal steel that has been made the hollow base apart sharp you want and later filled with a liquid or any other material that can use to your idea plastic products which will last millions of cycles. Some of the material that can be poured into the hollow space of the steel include plastic, metal, glass and even ceramic materials. The liquid is allowed to solidify and the block is broken to retrieve the mold that has acquired the shape of the block. Plastic mold is a custom mold that is using for making custom injection molding parts.
Plastic mold technology
Plastic mold technology is by far the most popular method to manufacture plastic parts in the world today. This process is used for everything from inexpensive commercial plastic products, like disposable eating utensils, toys to the severe environment, highly stressed technical components, like critical parts for automotive and aerospace industries. You’ll find extensive use of injection molded plastic parts in the electronics world for things like enclosures for cell phones, computers, televisions and the like, as well as in the medical world where things like syringe bodies, breathing apparatus and a wide range of other life-saving devices are employed. No other process has come to dominate modern manufacturing as plastic molding, and its use increases every year. Recently, critical steering components for General Motors cars and trucks were changed from stamped and machined steel parts to a plastic molded assembly resulting in a lighter part, at a lower cost, quieter, and more reliable.
What is Plastic Injection Molding
Plastic injection molding is the process of the heating thermoplastic resin to a liquid then shooting it under high pressure into a mold cavity that is the negative image of the desired part, allowing it to get cooling, then opening the mold to allow the completed part to be ejected out from the mold. In most cases, features can be built into the plastic mold cavity to give the part everything it will need when finished so that no other operations are needed once the part comes out of the mold. Textures, or high polishes, markings, screw holes, lens shapes, and any other features needed in the finished part can be built into the mold so the finished part automatically has these features incorporated.
The advantages of plastic molding
The beauty of plastic moulding is that many parts, even millions, can be made in exactly the same way and will come out the same no matter what. Each piece will have identical features, same dimensions, and physical properties. It is the ideal way to make high volumes because of this consistency. Properly maintained, injection mold can last decades making millions of parts per year. Properly set-up and controlled, the 20 millionth part will be identical to the first part in every measurable way. No other manufacturing process has the potential to operate at this consistency.
Multiple cavities of each part can be built to the plastic injection mould tool, so that each time the mold opens, you make 16 or 32 or 48 or some other multiple of parts for each cycle of the injection moulding machine to really increase the production rate and greatly decrease the cost of making a part. In some cases several different parts, for instance, a right and left-hand version of an enclosure can be made in a single mold as well to reduce the number of machine cycles required to make multiple parts of an assembly, increasing production and lowering the cost. Injection moulding also offers flexibility not possible with any of the other manufacturing processes.
Injection molding also offers one of the lowest scrap rates of any other manufacturing processes as well. Since no second operations are generally required, no material is cut off and thrown away. It is possible to use a special technique to completely eliminate even the small pathways the plastic flows through to cut the material scrap rate to virtually zero, or often, any plastic removed in the process can be reused by pelletizing it and mixing it back into the fresh plastic resin in closely controlled proportions. These capabilities mean a higher percentage of the raw material becomes part of the finished part than in any other process. Plastic injection molding is highly efficient.
