Overmolding can also be called overspraying which is a clear description of the procedure A previous ly manufactured injection molded part or substra te is oversprayed with a second molten mass in a further process step Aside from plastic parts even cords can be inserted manually or in a fully automa ted manner Depending on the plastic selected the most varied plastic parts or components can thus be manufactured For example multicolored injection molded parts made of the same but differently colo red plastics such as control knobs movable articula ted joints made from different plastics like toy figures with movable arms or hard soft combinations made of hard basic plastics over which an elastic material is sprayed as is the case for example with connector casings with injected seal Two are better than one Focus Overmolding Focus Versatile precise and cost efficient The overmolding process is one of the most commonly used processes in the plastics industry and makes it possible to manufacture parts and components quickly and economically Thanks to its many years of experience with a wide range of products Greiner Assistec ranks among the trailblazers in the industry with know how and expertise clearly proven even in current new projects Facts Material PA PP Technology Injection molding overmolding Facts Material PA Technology Injection molding overmolding lacquering BMW Daimler Retaining strap Three in one Greiner Assistec in collaboration with Greiner Perfoam is contributing to the retaining strap for the rear shelf in the BMW Series 1 and in the Mercedes Benz GLA The polyamide cord is over molded directly in an innovative vertical injecti on molding machine In the past the three stage process required three separate forms but the ma chine designed by Greiner Assistec now combines the three steps in one single form This significant ly reduces costs and saves time Precisionand accuracy are ensured by means of an automatic device BOS Audi Roller shades Greiner Assistec has contributed an end cap to the roller mechanism for roller shades in the VW T6 for BOS the automotive supplier The metal part is overmolded with plastic to give the composite part not only exceptional rigidity and durability but also to lessen the weight The overmolding process involves automated insertion of the metal part The feeder and insertion station was custom developed and is characterized by a clearly defined process low personnel cost reduced expenses low error rate and reproducibility 4 01 17 unique plasticspaper Greiner Assistec has impressed many custo mers in past years with its know how in the field of overmolding The latest projects clearly mirror the wide range of challenges and solution approaches One process many uses
