Publication number: 20100187723Abstract: A method for producing a multilayer molded article is proposed, whereby a thin cover layer can be formed widely on a substrate layer. The method has a first step of placing a substrate in a cavity formed between a pair of mold halves, and a second step of supplying a second thermoplastic resin material being in a molten state, at an injection rate of 200 cm3/sec or more to a clearance formed between the substrate and a cavity surface facing the substrate, wherein in the second step, the clamping force of the pair of mold halves is set so that the cavity volume will increase due to pressure increase in the cavity accompanying the supply of the second thermoplastic resin material. The method is useful for producing large-sized plastic components with excellent appearance quality.Type: ApplicationFiled: January 27, 2010Publication date: July 29, 2010Applicant: SUMITOMO CHEMICAL COMPANY, LIMITEDInventors: Taro Miyazawa, Kenichi Higashi
