IN-MOLD COATING MOLDING METHOD AND IN-MOLD COATING-MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for molding an in-mold coating-molded article, which can optionally control a coating film thickness and has a uniform coating film without.;SOLUTION: An in-mold coating molding method for applying coating on the surface of a resin molding using a molding machine equipped with a mold device formed with a cavity, a mold clamping device, an injection device, an injection unit, and a device for jetting gas into the cavity includes the first process for injecting/packing a reactive resin by the injection device into the cavity of the mold device mold-clamped by the mold clamping device, the second process for obtaining a molding through the curing reaction of the reactive resin, the third process for injecting a coating agent having a volume of 40-100% of the volume of a space in the cavity while the resin injected into the cavity is cured/contracted through a polymerization reaction, the fourth process for jetting gas from the back side of the molding after the injection of the coating agent is completed, and the fifth process for holding a pressure applied to the coating agent so that the pressure applied to the coating agent may be kept higher than 0 Pa until the coating agent is cured completely.;COPYRIGHT: (C)2010,JPO&INPIT
