<p>PURPOSE:To easily and quickly blow-mold a hollow molded part covered by jacket bodies with cushioning property in a single process by a method wherein jacket bodies, which are laminated with cushioning medium and are a little larger than the hollow molded part, are set in a split-cavity mold for hollow molding. CONSTITUTION:A jacket body 2 consists in laminating cushioning medium 4 made of soft foamed resin material and outer skin 3, which is made of thermoplastic resin sheet and is a size larger than said cushioning medium. Said jacket bodies 2 are set in a die 5 for hollow molding, a parison 6 is inserted between the bodies 2 and blow-molding is performed. After that, a hollow blow- molded part covered by jacket bodies 2 with cushioning property is manufactured by cutting flashes 10 off. The titled molded part is suitable for manufacturing a vehicular head rest, a console box and the like, because the jacket body can be laminatedly made into an integral body simultaneous with blow-molding.</p> |
