Abstract

PURPOSE:To obtain a coupler having corrosion-resistant inner and outer faces by a method in which a coupler is set in split molds, a slide core is inserted into the coupler to form a cavity between the periphery of the coupler and the molds and also between the inner surface of the coupler and the core, and a resin is injected to cover the inner and outer faces of the coupler. CONSTITUTION:A metal coupler 22 to be coated with a resin is set in split molds 2, and a slide cores 8-9 are inserted into the opening 3 of the molds 2. Thereby, an outside cavity 3B is formed between the coupler 22 and the molds 2, and an inside cavity 3A is formed between the coupler 22 and the cores 8-10. A molten resin is injected into the cavities 3A and 3B to obtain the coupler whose inner and outer faces are covered with the resin.
