Abstract

PURPOSE:To attain sucure operation by positioning a resin-pouring gate of a metal mold on the opposite side to the thin layer viewed from the center of the sealing body, so that the formed thin part may have less strength. CONSTITUTION:The resin-pouring gate 3 is positioned on line I opposite to line II connecting a thin layer 5 of a round mould 2 and the center of the mould. Therefore, molten resin runs along the direction of arrow marks and a surface welded with resin is formed almost on the line II. As the layer welded with resin is processed through fusion at the lowest temperature in all, this layer is weaker than other parts, and easily subjected to cracks caused along the welded surface under a certain definite pressure. Either one of polyethylene, polyamide, polypropylene or polysulfone is desirably employed as the thermoplastic resin to feed.
