About Injection molding machine
Injection molding is plastics equivalent of metal die casting. This is the mos twidely method of mass producing to close tolerance three dimensional article over a wide range of sizes and variety of shapes (which can be quite complicated), Using most of the thermoplastic material which are available as granules and powders. Injection moulding process includes plastics material, mold and injection molding machine. In addition to this the man behind the operation is very important, as he should have good understanding of this subject. In this process the plastic granules are converted into melt in the plasticizing unit of machine and then this melt is injected into a clamped mold by the machine. The mold consists of two halves namely core half and cavity half. The space between core and cavity of the mold is filled with hot plastic melt.The melt than takes the shape provided by the mold on freezing the melt. The freezing of plastic melt in mold is due to the cold water circulation...
