The Construction of the machine is very simple as compared now days machine. It works like a hypodermic punch, using a piston and plunger, injection of plastic through a cylinder whose temperature is very high into the cavity of the mold.

Injection Molding Process, Defects, Plastic

First, the molten plastic enters the mold through the sprue. Additional channels, called runners, carry the molten plastic from the sprue to all of the cavities that must be filled. At the end of each runner, the molten plastic enters the cavity through a gate which directs the flow. The molten plastic that solidifies inside these runners is attached to the part and must be separated after the part has been ejected
