Compression Mounting

Compression molding techniques are used to produce hard mounts in a minimum of time. The materials used are classified as: (1) Thermosetting and (2) Thermoplastic. Thermosetting media requires heat and pressure during molding cycle and can be ejected at maximum molding temperature. Thermoplastic materials remain fluid at maximum molding temperatures and become dense and transparent with a decrease in temperature and an increase in pressure. Thermosetting plastics soften from a temperature of approx. 70° C and cure due to a chemical reaction at approx. 150° C. Thermoplastics melt at a temperature of approx. 160° C.
