INJECTION MOLDED BODY AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To easily disjoin semi-finished articles 2 and 3 and to recover them as individual parts on the occasion of manufacturing a finished article 1 by integrating the molded semi-finished articles 2 and 3 by secondary injection. SOLUTION: A screw space is formed in each of the semi-finished products 2 and 3, and an injection material that is hard to adhere to the semi-finished articles 2 and 3 or does not adhere thereto is injected into the screw space so as to mold a screw 4, in a state wherein the semi-finished articles 2 and 3 are butted to be subjected to secondary injection. According to this constitution, the semi-finished articles 2 and 3 are integrated with each other, while they are made disjoinable.
