Abstract
A method for molding thermoplastic articles comprising: a) providing a mass of thermoplastic material at a sufficient viscosity so that the material retains its integral mass ratio in the absence of compression pressure but which is nevertheless of sufficiently low viscosity to allow its flow under a compression pressure; b) introducing the mass of thermoplastic material into the cavity of a compression molding apparatus; c) closing the molding apparatus on the mass of the thermoplastic material rapidly and with sufficient compression force to cause the thermoplastic material to flow and fill the mold cavity to experience significant heat transfer; d) maintaining the forces of compression molding in the thermoplastic material over a period of time to remove a sufficient amount of heat so that the plastic material is able to be handled in a newly formed configuration; e) removing the compression molding forces and f) ejecting the thermoplastic article.
