Manufacturing method for multi-layer molded-product consisting of a base having holes through and a covering material

摘要

A method for manufacturing multi-layer molded-products, including the steps of supplying molten thermoplastic resin between an upper mold and a lower mold, and applying pressure to a forming cavity by clamping in a forming process. With this method, it is possible to easily produce a multi-layer molded-product wherein the covering material, such as a woven fabric, is entangledly fused to and integrally formed on the surface of a base plate with at least one hole that is made of thermoplastic resin.
