Abstract
A method which can prevent primary mold products from being deformed or broken during a secondary molding process to improve joining strength of joining portions. In the method for joining a plurality of primary mold products 6, 7, formed by a separate process with each other, in a secondary molding process, a secondary mold resin 13 is injected to joining portions 12 after the surfaces 10 and 11 of the joining portion 12 of the primary mold products 6, 7 to be joined have been heated.
Claims12
A method for joining resinous products comprises a secondary molding process in which a plurality of primary mold products molded in a separated process are joined together by injecting a secondary molding resin into joining portions of the primary mold products after only the surface areas of the joining portions of the primary mold products to be joined together have been heated.
A method for joining resinous products comprises a secondary molding process in which a plurality of primary mold products molded in a separated process are joined together by forming tubular paths with joining surfaces of the primary mold products to be joined together by abutting the joining surfaces with each other and by injecting a secondary mold resin into the tubular paths after heating the joining surfaces by supplying a heating medium into the tubular paths.
