Abstract

PURPOSE: To obtain easily an injection molding decorated by a covering sheet only for necessary parts by cutting off the unnecessary part of a covering sheet having a shape matching an injection mold to form an opening and then injecting a resin into the back side of the covering sheet.
CONSTITUTION: A covering sheet 1 of a resin, whose surface is provided with a wood grain pattern, is preliminarily molded so as to match the shape of an injection mold, and then the unnecessary part of the covering sheet is cut off so as to form an opening 2. The covering sheet 1 so cut is placed in the injection mold and then a resin 3 is injected into the back side of the sheet 1. And, a transparent plate is fitted to the opening 2 in order to utilize it as the board of various meters and switch plate, etc. Or, the opening 2 may be closed with a transparent or colored resin molding 3 to form an exposure 7.
