what are the closed mold methods for processing fiberglass composite products?

Solution

LRTM Method : A composite molding process with two counter molds (male and female). Typically, the molds are joined, vacuum clamped, and resin is injected using vacuum assist into the mold cavity

Compression Moulding Process :Compression molding is a closed mold process . The material charge is manually or robotically placed in the mold, the heated mold halves are closed, and up to 2,000psi of pressure is applied

DCPD Reaction Injection Molding (RIM) Process :Thermoset DCPD RIM (Reaction Injection Molding) involves a closed tool, low PPM moisture and low PPM oxygen environment

Resin Transfer Molding (RTM) Process : RTM is a vacuum-assisted, resin transfer process with a flexible solid counter tool for the B-side surface compression

LCM Process : LCM (liquid composite molding) process for compression molding with pre-placed fiber reinforcement.
