Process for the manufacture of a body provided with a plurality of openings

摘要

In the process for manufacturing a body provided with a plurality of openings, which body can be sheet-shaped, dish-shaped or sleeve-shaped and has a decorative layer on the outer side and/or a protective layer on the inner side, the body is first provided with blind holes open to the outer side and subsequently provided with the protective and/or decorative layer. Opening channels which extend from the blind hole bottom as far as the inner side of the body wall are then incorporated in the area of the blind holes. It is advantageous to form the dimensions of these opening channels smaller than the dimensions of the blind holes.
