Know Your Options in Injection Machine Nozzles | Plastics

Jan 27, 2015 · In todays global manufacturing environment, molders are looking to optimize their injection molding processes in every way possible. Various types of machine nozzles can help accomplish that goal. Machine nozzles today can provide a variety of functions, including filtering, mixing, and shut-off of melt flow.

Plunger Injection Molding Machine | Professional

The plunger injection molding machine pushes forward the fused plastics in the charging barrel through the to-and-fro movement of plunger therein, and the spreader further injects them into the mold cavity through the nozzle. The plastication of plastics in the charging barrel mainly depends on the heat provided by the outer heater of charging barrel.
