Abstract

PURPOSE:To obtain the desired titled article continuously and efficiently, by a method wherein the foamed body of a specified crosslinked thermoplastic resin is laminated with a parison by fusion bonding in a mold for blow molding. CONSTITUTION:A tubular parison 1 of a thermoplastic resin is extruded through an extrusion die by a desired length. Then, the foamed body 3 of a crosslinked thermoplastic resin having a gel fraction of at least 5% and formed into a desired laminatable shape is fitted in bisected molds 2, and while supporting the molds 2 by a support 7, the molds are clamped so that the parison is clamped between an upper part and a lower part of the molds. By blowing a gas into the inside of the parison while the parison is at a temperature of not lower than the softening point of the resin constituting the parison, a hollow molded body 4 is produced and the foamed body is fusion- bonded to the outside surface of the body 4, whereby the foamed body 3 is laminated on the outside surface of the hollow molded body 4 with a uniform and sufficient bonding strength. Thereafter, the hollow molded body is solidified by cooling, the molded article is taken out by opening the molds, and trimming such as deflashing is conducted to obtain the hollow molded article with the foamed body laminated thereon.
