PROBLEM TO BE SOLVED: To realize a favorable assembling properties and reduce the production cost of a molding without limiting the mounting position of the molding by a method wherein an insert is placed in advance within a parison so as to blow mold the parison under the state just mentioned above in order to make the insert integrated. SOLUTION: A parison P is formed by extruding a molten resin from the die 63 of an extrusion molder part so as t place an insert 42 at the tip of the rod 64a of a cylinder 64 from the opening P1 side of the parison P. Next, by raising the rod 64a, the insert 42 is set in the interior P2 of the parison P. By setting the insert 42 at an arbitrary position of the parison P before the blow molding of a blow molding 40, the insert 42 can be integrally molded at the arbitrary position or the intermediate position of the molding. Next, after blow molds 65a and 65b are clamped together, an air is blown in the interior P2 of the parison P for blow molding. Under the state just mentioned above, the perfect shape of the molding 40 is realized. During the manufacturing process of the molding 40, the insert 42 can be integrally mounted onto a molding main body 41. |
