It is suitable for recycling common waste plastic products such as polyethylene (plastic film, beverage bottles, plastic bags, etc.) or polypropylene (waste woven bags, packing bags, tied ropes, etc.).

The injection unit of injection molding machine is much like an extruder. The injection unit melts the polymer resin and injects the polymer melt into the mold. It consists of a barrel that is fed from one end by a hopper containing a supply of plastic pellets. The unit may be: ram fed or screw fed.

This last method involves the use of the plastic injection molding machine itself, as dry pigment powder is mixed directly with plastic pellets in the machine’s ‘hopper.’ When you achieve the perfect ratio of 2% by volume, then the mixing process can begin.
