Compression molding is done amongst matched metallic molds utilizing sheet-molding chemical compound (SMC), bulk-molding chemical compound (BMC), or preform mat. H5N1 weighed accuse of SMC or BMC, or a preform of drinking glass reinforcement shaped to the mold is placed on a press ranging inward size from 300 to 4,000 tons. Resin is added amongst the preform piece SMC together with BMC incorporate all components including fiber, resin, fillers, catalyst etc. Heat together with pressure level is applied, amongst temperature ranges of 225 to 325 oF. together with 150 to 1,000 psi pressure level required to cure parts. Cycles tin laissez passer on notice arrive at from less than 1 to 5 minutes. Typical thermoset resins used inward compression molded parts are polyesters, vinyl esters, epoxies, together with phenolics. Compression molded products vary from dinnerware, trays, buttons, appliance housings, large containers, electrical, to recreational vehicle trunk panels such equally snowfall mobiles, together with jetskis.
