Plunger injection molding
From Plastics Wiki, free encyclopedia
Plunger injection molding The design of the plunger machine is ideally suited for molding thermoset molding compounds and bulk molding compounds. In the plunger machine, the molding compound is fed into the heating cylinder (barrel). The plunger or ram forces the compound through the cylinder where it is heated by conduction of heat from the cylinder wall. As the material is forced forward, it passes over a spreader or torpedo within the barrel that causes mixing. The plunger forces the material through the nozzle and into the mold.
