METHOD FOR PRODUCING INJECTION-MOLDED ARTICLE

摘要

Disclosed is a molding technique, which is for obtaining a molded article having an excellent appearance, and which suppresses fibrillization of the surface of the injection-molded article even if the liquid-crystal resin composition is ultrasonically cleaned. Specifically, disclosed is a molding technique which can be performed even under the condition that the mold temperature is no greater than 100ºC. During injection molding of a liquid-crystal resin composition, when a mold with an thermal insulation layer formed on the inner surface of the mold is used, with the thickness of the thermal insulation layer being t1 (µm), the injection speed being S (mm/sec), the thickness of the injection-molded article being t2 (mm), and the die temperature being T (ºC), injection molding is performed under molding conditions that fulfill a particular relationship. Preferably, molding is performed with a mold temperature that is no greater than 100ºC.
