  • Patent number: 7790081
    Abstract: A process producing an in-mold coated molded product. The process molds a thermoplastic resin material under a mold-clamping pressure in a mold including a fixed mold part and a movable mold part each heated at a predetermined temperature, separates the fixed mold part and the movable mold part when the molded material surface is solidified such that it is durable to a pressure of injection and flow of a coating agent, and injects the coating agent containing a thermosetting resin material between an inner surface of the mold and the molded product obtained. The process also coats the molded product surface with the coating agent as the mold is re-clamped after injecting the coating agent, takes out the molded product coated with the coating agent when the coating agent is cured such that it is neither peeled off nor cracked by opening the mold, and re-heats the molded product after taking it out.
