Embodiment Construction
[0096] Such as figure 1 As shown in the schematic process flow diagram of , in method step 1 a daughter body made of non-electroplatable plastic A (for example, polycarbonate) is produced by injection molding in an injection mold. The shape of cast plastic is essentially defined by the mold, more specifically the cavity. In addition, other parts can be placed in a mold onto which the plastic composition A is cast.
[0097] In method step 2, an electroplatable layer of electroplatable plastic B (for example, ABS / polycarbonate blend) is injection molded on the front side of this sub-body, so that the base body of the control element according to the invention is formed as a double Component (2K) parts. Method steps 1 and 2 can also be carried out in reverse order.
[0098] In a subsequent optional method step 3, at least the surface of the electroplatable layer of the control element is subjected to a pickling process in which the butadiene moieties are eluted from the surfac...
