Compression Molding - an overview | ScienceDirect

A typical compression molding process is performed at a mold temperature of 350°F and mold pressure of 100 psi (180°C and 700 kPa) with curing time of 3 min. After the material is cured, the mold is opened and the plastic package is pushed out. Compression molding is a low cost process and is capable of high volume production.

Injection Molding - an overview | ScienceDirect Topics

Plasticizing involves high torque and low rotational speed, while injection requires high force and medium speed. A source of motive power is needed to drive these movements. The modern injection molding machine is virtually always a self-contained unit incorporating its own power source. Early machine frequency ran from a centralized source serving an entire shop or factory.
