Abstract
Development of two systems of precision molding process for plastics assisted by infrared laser irradiation is described in this paper. The first process is able to improve both the optical quality and the replication ability of plastics by radiant heating on the moving polymer melt injected in the mold cavity through an optical-crystal material window, which transmits the infrared radiation. The second process is a press molding one for replication on to the surface of solid blank work pieces from a grooved stamper using a similar IR-laser irradiation. This system has also an ability of high-precision replication minute mold surface configuration to the one of plstics. Both proposed processes showed remarkable efficiency.
