PURPOSE: To realize the molding of respective product halves out of different resins under the condition that the fill to a filling device is held constant by a method wherein a plurality of positional relationships in which each combination of the cavity of a fixed mold and the core of a movable mold for molding the product half of a hollow article on the fixed mold side can be obtained, are provided. CONSTITUTION: After one set of product halves A and B, which are bottomed and cylindrical ones and the outer peripheries at the ends on the opening part side of which are made into small diameter parts (a) and (b), are formed by molding, both the product halves A and B are abutted against each other so as to block their respective opening parts with each other in order to fill bonding resin by forming in a groove made by both the small diameter parts (a) and (b) between the product halves, resulting in welding both the product halves A and B together so as to form a hollow article. Accordingly, respective works such as the molding of a pair of product halves, butting and sealing and the like are executed in succession. Thus, the resins, out of which the product halves are made respectively, or the resin used for sealing the product halves are made to be different from one another. |
