Definitions

the invention relates to a partially galvanizable molded polymer part.
This object is achieved with a molded polymer part, the partial areas of which can be galvanized or non-galvanizable polymers and by grooves with a V-shaped profile from each other are separated, the partial areas consisting of galvanizable polymers being a galvanic coating exhibit.
the invention differs from the prior art in that the partial areas of the molded polymer part consist of polymers optimally matched to the respective treatment, so that Protective treatments, covers and removal of layers are eliminated. Generation treatments other decorative layers are possible without intermediate stages.
electroplating layer is facilitated by the fact that the electroplated polymers existing sections each have a tab for connecting a contact pliers.
a galvanizable polymer from the group of ABS is used for galvanic treatment (Acrylonitrile-butadiene-styrene copolymers), ABS.PC blends (acrylonitrile-butadiene-styrene.polycarbonate copolymers).
a preform is first placed in a first cavity of an injection molding machine is formed from a galvanizable or non-galvanizable polymer that thereafter in a second, the preform receiving the cavity of the injection molding machine from an additional molding a non-galvanizable or galvanizable polymer is formed and that finally the surfaces of the galvanizable polymer.
a groove 7 with a V-profile or widened V-profile embedded in one side surface In the area of the joint 6 between the preform 2 and the additional molding 3 is at least in a groove 7 with a V-profile or widened V-profile embedded in one side surface.
the V profile of the groove due to the geometry that the electroplating layer 8 on the wall of the V-profile into a thinner expiring wedge edge 9 and ends at the foot of the V-profile of the groove. This results in a cleaner one optical transition.
Fig. 2 is the preform 2 as a film, blow molding or the like formed from a galvanizable polymer.
the preform 2 is in a cavity, not shown inserted and back-molded by the additional molded part 3 from a non-galvanizable polymer.
the preform 2 made of galvanizable polymer is provided with a tab 4 for contact pliers 5 provided.
a wedge edge 9 of the electroplating layer 8 forms on the foot wall of the V-profile groove 7 out.
