Plastic product painting mask

摘要

A painting mask, which has an edge portion for defining a painting area parting line, is formed in a mask body which has a predetermined dimension enough to cover a work made from plastic, the mask body including a mask body base portion which is composed of a metal plate with a dimension substantially matching a work, and a painting area circumferential edge portion which is molded integrally with the mask body base portion by curing a thermosetting plastic (epoxy resin) prepared like clay and in which an edge portion for defining a parting line for a painting-presumptive area is formed. The mask body base portion does not shrink during the process where the mask body is manufactured, so that a painting mask with a proper dimension can be obtained.
