Most of two-color handles are made by rotary axis plastic injection moulds. Rotary axis process or rotary core process means that the two-color plastic injection mould won't rotate by injection machine, however, the cores of mold will be rotated by injection machine or cylinder of injection mould. When the injection part will be made the second color, the controller of injection machine will deliver signal of core pulling system to rotate the 1st core of mould to second position of core, then make the second color injection.

Customized 2 shot plate injection molding Factory:Plastics can also be divided into general plastics and engineering Plastics. Its main purpose is to define a wide range of applications. Polyethylene and polypropylene, for example, are cheap and can be produced on a variety of different types of machines. Engineering Plastics are expensive, but the stability and physical properties of raw materials are much better.In general, they are both rigid and resilient.
