Abstract
PURPOSE: To obtain a formed product having good appearance, even if a sheet or parison defective of die line or rough surface is used, by following method in which a thermoplastic resin is formed by means of momentarily heating the surface of a mold by high freguency induction heating.
CONSTITUTION: The surface of mold 5 is heated selectively and momentarily above the plasticization temperature of resin by high frequency induction heating. The sheet or parison of thermoplastic resin is thermally formed or extruded to a hollow product, thereby, the product of the thermoplastic resin has degree of luster GS(60°) (ASTM D523) above 80%. As the thermoplastic resin, high impact polyethylene, acrylonitril-buthylene-styrene series resin, polyphenylene ether resin, high density polyethylene and polypropilene etc. can be utilized.
