PRESSURE ARE MAINTAINED UNTIL THE MOLDING MATERIAL HAS CURED. THE PROCESS EMPLOYS THERMOSETTING RESINS IN A PARTIALLY CURED STAGE, EITHER IN THE FORM OF GRANULES, PUTTY -LIKE MASSES, OR PREFORMS. COMPRESSION MOLDING IS A HIGH-VOLUME, HIGH-PRESSURE METHOD SUITABLE FOR MOLDING COMPLEX, HIGH-STRENGTH FIBERGLASS REINFORCEMENTS. ADVANCED COMPOSITE THERMOPLASTICS CAN ALSO BE COMPRESSION
