An injection molding machine is used to produce plastic products using pelleted or granular raw plastic by melting, injecting, packing and cooling cycle. A number of parameters are considered during the injection molding process including the injection rate, pressure, mold thickness, screw design, etc. Injection molding machine can be classified into three different categories: general-purpose machine, precision, tight-tolerance machine and high speed, thin-wall machine. The major equipment auxiliary to the molding machine includes material-handling equipment, resin dryers, mold-temperature controllers and chillers, granulators, part-removal and part-handling equipment. An auxiliary injection molding machine can be used for many applications that require producing any solid plastic from bottle caps to car parts. Plastic injection molders work by filling melted plastic inside a clamp that contains the mold. The final shape created is a reverse image of the mold. Auxiliary equipment are high-versatile in producing simple and complex plastic products without extra cost and with precision.
