摘要
PROBLEM TO BE SOLVED: To provide an injection-molded product with a pattern which is free from restrictions in terms of a molding through a die and easily realizes its pattern formation on a design face without increasing a manufacturing cost and generating a molding failure and a strength deterioration and an injection molding die and a method for manufacturing an injection-molded product with a pattern. ;SOLUTION: In the injection-molded product with a pattern which has one of faces in the thickness direction as a design face where the pattern is formed and the other face as a non-design face, a difference in the luster of the design face occurs because the solidification rate of in the thickness direction differs between a part corresponding to the pattern and an adjacent part where the pattern is not formed to the pattern part. Consequently, the pattern part is distinguished from the non-pattern part by the luster difference and is formed on the design face.;COPYRIGHT: (C)2003,JPO
