    摘要： A method of forming a multi-layer, co-injection molded article is disclosed. In an embodiment inner, middle, and outer layers of a polymer material are co-injected, and the velocity of the co-injection of the inner, middle, and outer layers are controlled. In embodiments of the method, the velocity of the co-injecting is less than about 0.390 inch/second. With embodiments, the articles may be formed from polyethylene terephthalate (PET). Articles, such as preforms, that are formed from a co-injection process, in which velocity is controlled, are also disclosed.

    摘要： An RTM method, which injects and impregnates resin from a plurality of injection ports into a preform placed inside the cavity of a molding die, wherein the plurality of injection ports are disposed in first positions in the central section of the cavity corresponding to positions of the preform located in a product area of an article to be finally molded and second positions located in the periphery of the cavity corresponding to positions outside the product area of the article to be finally molded or corresponding to positions inside the cavity but outside the preform area, and the timings for closing the injection ports after resin injection are made to be different from each other between the injection ports of the first positions and of the second positions. In an RTM method that injects resin from a plurality of injection ports, the invention is able to achieve both high-velocity resin impregnation and improvement of the quality of a molded article.
