Multi-layer molding method

摘要

There is provided a multi-layer molding method by which a molding product of multi-layers, in which a second layer is locally formed on a base layer, is produced, and the multi-layer molding method comprises the steps of: forming locally a cavity for forming the second layer between the first mold and the second mold; injecting a second resin into the cavity for forming the second layer so as to mold the second layer; separating relatively the first mold and the second mold from each other so as to form a cavity for molding a base layer continuously between the first and the second molds and also between the second layer and a mold surface opposing to the second layer; and injecting resin for the base layer into the cavity for molding the base layer.
