METHOD FOR MANUFACTURING PLASTIC MOLDINGS

摘要

PROBLEM TO BE SOLVED: To continuously manufacture high-precision plastic moldings. SOLUTION: This method for manufacturing the plastic moldings follows such steps that a plurality of press molding devices 3 are disposed on a conveyor 6, then a thermoplastic or a heat-curable material 2 to be molded is loaded into a molding die set in each of the press molding devices 3 and the devices 3 are made to pass through a heat-up zone 51 for heating up the material 2 to a temperature level below a softening point in such a state that a pressing force is applied to the material 2 by a molding jig 4, a heat insulating zone 52 for keeping the described temperature for a specified time and a cooling zone 53 for cooling the moldings.
