4 Recent developments in press design and process optimization 

To improve process productivity and part quality, many parameters should be optimized in the compression molding process. The principal parameters 

Manufacturing techniques for polymer matrix composites (PMCs) 

Resin paste formulation, SMC maturation period, SMC sheet thickness, SMC storage temperature Mold temperature, molding pressure, mold closing speed, precharge specification (size, shape and location) 

Part design (ribs, bosses, thickness, radius), air vent, shear edge, ejection system, parting line, draft angle, tool material, surface finish
