INJECTION MOLDING APPARATUS AND METHOD FOR INJECTION MOLDING

摘要

PROBLEM TO BE SOLVED: To realize both to decrease cost and to improve manufacturing efficiency by performing simultaneously injection molding process and printing on a molded article and omitting printing process and to obtain a good printed pattern by solving problems such as strain and positional deviation of the printed pattern. SOLUTION: A printing member 7 corresponding to the shape of a pattern to be printed is provided so as to embed it to the face side for forming a cavity 2 of a mold 1 and an ink is injected in such a way that the ink is made to permeated through fine holes of the printing member 7 by applying a pressure to the ink K during injection molding to perform printing on a molded article in the space 6 for the molded article.
