PURPOSE:To prevent the generation of bubbles in the cavity which will become a manufactured article as well as to contrive improvement in damp-proof properties by a method wherein a subcavity, to be used to release the bubbles which will not become a manufactured article, is provided communicating to the cavity for which resin filling is finished. CONSTITUTION:In the cavity 7 of the molding consisting of a top force 5 and a bottom force 6, a dummy subcavity 13 which will not become a manufactured article is provided in a interconnecting manner on the part where the branched flows of resin join together as shown by an arrow in the diagram, i.e., on the side wall of the cavity 7 located at the part opposing to a gate 10. The resin containing air located at the resin junction part of the cavity 7 is released to the cavity 13. As a result, bubbles 12 are transferred to the subcavity 13, and no bubbles are generated in the cavity 7 which will be formed with the manufactured article. |
