Abstract: There exist the problems of inefficiency process and high-cost aftertreatment technology in products of thermoset DMC. This paper analyzed the characteristics of process scheme such as DMC compression molding, injection molding and delivery molding and gave the selection principle of process scheme of DMC products in circuit breakers. In allusion to the compression molding workpieces, the trimming frock with case-molded pedestal pneumatic was designed to raise the efficiency of plastic part aftertreatment greatly.
Key words: circuit breaker; DMC; compression molding trimming; frock design
