C-RTM Process


With Compression Resin Transfer Molding process, the resin mixture is fed into the mold when it is slightly open allowing partial impregnation. Then a compression stroke presses the resin through the preform for complete impregnation. By this way an high-pressure resin injection allows the use of fast-curing systems.
