PURPOSE:To prevent the generation of defectives due to the stagnation of air by a method wherein the main body of a molded form is molded under a condition that a coating sheet, molded to a predetermined shape by vacuum molding after heating, is arranged in a mold. CONSTITUTION:A coating sheet 14, softened by heating through a heater panel 23, is set into a split mold 20 equipped with deaeration holes 20b, and is molded by vacuum molding to provide the sheet 14 with a predetermined shape. A parison 17 is extruded between split molds 19, 20 under a condition that the coating sheet 14 is set in the split mold 20 and a mold is clamped while blowing preliminarily air into the parison 17, then, the air is blown into the parison 17 fully to mold the main body 12 of a molded form and the coating sheet 14 is bonded to the predetermined position of the surface of the main body 12 of the molded form whereby a coating layer 13 is provided. Subsequently, a slide core 21 is moved to roll the terminal positions of the molded form main body 12 and the coating sheet 14 to the inside thereof and the molded form is cooled for a predetermined period of time, thereafter, the terminal sections are processed whereby the molded form 12 may be obtained. |
