Molding Machinery—Coking and Charring

To eliminate risks of damaging machinery or breaking down oil compounds, hot oil units are equipped with low-watt density heaters. These heaters are used to balance oil used in molding machinery to prevent the oil from “coking” or “charring.”

Measures taken such as the use of these heaters, resolve coking and charring issues. A vacuum pump is utilized to provide appropriate flow through molding machinery.

A vacuum pump is what moves heated resin through the mold. Instead of the conventional pressure process, hot oil units employ vacuum pumps instead, pulling materials through with pressure.

The extrusion machinery pulls raw material, like plastics or resin into configuration guides that create stock components. A hopper is at one end of the molding machinery where the resin is fed to the screw, ram or plunge. The opposite end where the resin is pushed holds the die that will shape the resin.
