METHOD FOR MOLDING TPO POWDER SLUSH

摘要

PROBLEM TO BE SOLVED: To perform powder slush molding of a TPO (thermoplastic elastomer) molded article without generating pinholes and to improve mold release property of the TPO molded article after molding. SOLUTION: A mold 1 with venting holes 7 is heated. A TPO powder is brought into contact with a molding face 2 by rotating the mold 1 to form a TPO molten film 23 and the TPO molten film is sucked on the molding face 2 by making the back face side of the mold 1 vacuum to eliminate gaps 25 and to remove air 24 included in the TPO molten film by suction. The TPO molten film 23 is solidified by cooling the mold 1 to obtain a TPO skin molded article. The TPO skin molded article is air-pressed by pressurizing the back face side of the mold 1 to peel it off from the molding face 2.
