METHOD FOR OBTAINING INJECTION-MOLDED ARTICLE OF THERMOPLASTIC RESIN HAVING HIGH QUALITY APPEARANCE

摘要

PROBLEM TO BE SOLVED: To provide a molding method capable of obtaining an injection-molded article having desired high quality appearance without extending a molding cycle time in a conventional injection molding method to a large extent. SOLUTION: A molding method shortening a molding cycle time while keeping the appearance of a molded article well is obtained by controlling a temperature gradient of heating/cooling and/or the flow rate of a heating medium/ cooling medium in a conventionally known method for obtaining an injection- molded article of a thermoplastic resin having high quality appearance.
