 Chapter 5 : Manufacturing Process
In the compression molding process, illustrated in Figure 7-6, a thermoset plastics, phenolic, melamine, or polyester, is molded in an enclosed mold between two heated platens.
The platens that hold the two halves of the mold are heated to approximately 350 degree F. Pressure in the range of 1,500 PSI is exerted on the material.
The mold is heated to the curing temperature of the resin varying from 325 degrees to 400 degrees F. The process produces parts with uniform thickness and fully cured resin.
