COMPRESSION MOLDING SYSTEM

摘要

An automatic compression molding system, especially for thermosetting materials, in which an extrusion screw or a number of extrusion screws preplasticize the powder and charge the preplasticized mass into preforms. The preheated and preformed masses are immediately delivered and loaded into the mold cavities to reduce the time of the cure cycle up to 80 percent of that required in cold powder compression molding.
