摘要

Annular grooves (11), which essentially have v-shaped cross-sections, are formed on the front and rear surfaces of a grill element (2). Furthermore, a through-hole (17), which connects the front and the rear surfaces of the grill element, is constructed in such a way that the front opening is smaller than the rear opening. A projection (19) is formed on the rear surface of the grill element and is located inside the groove. The grill element is immersed in a chemically electroplating solution, in order to form a chemically electroplated layer (15) on the entire surface of the grill element apart from the floors of the grooves. The grill element is then subjected to electroplating of the underlayer, during which the grill element is immersed in a predetermined electroplating solution. In this case, the projection is used as a type of electrode in order to charge electrically the chemically electroplating layer, which is located on the front surface of the layer, which is located on the projection, so that it is possible by means of the layer which is located in the full hole for an electroplated underlayer (16A) to be formed on the sections and which an electroplated decorative layer is formed. The chemically electroplated ... Original abstract incomplete IMAGE
