Compression Molding Process

▌ Process Principle

Place prepreg, molding compound, or fiber-resin mixture into metal matched molds, then apply pressure and heat to make the material flow and fill the mold cavity inside the mold; after curing, a part consistent with the mold cavity shape is formed. Classified by pressure source, it is divided into mechanical compression molding and hydraulic compression molding.

▌ Advantage

Extremely high production efficiency: The single molding cycle is short (3-30 minutes), suitable for mass production;

High dimensional accuracy: Tolerance can be controlled within ±0.1mm, with good surface quality;

Wide material adaptability: Compatible with various raw materials such as SMC, BMC, and prepreg.

▌ Application

Automotive Industry: Bumpers, dashboards, engine hoods (SMC products), etc.;

Electrical Industry: Insulation covers, switchgear components, etc.;

Daily Necessities: Bathroom components, table and chair frames, etc.;

▌ Equipment Used
