Seeking coatings to protect and enhance zinc diecast components
Project Size 1,000,000 € · Deadline : 2018-02-16
The current manufacturing process involves die casting of the components which are mainly zinc, although other substrates and manufacturing processes are also employed. These components are then electroplated with copper which makes the surface more uniform, assures good electrical conductivity and enhances adhesion of other coatings. Subsequent nickel plating provides a superior corrosion resistant barrier, and then a range of decorative finishes can be applied thereafter. This combination of conventional processes however, is complex, lengthy, costly and often results in the generation of hazardous and environmentally detrimental waste products. Our client is therefore seeking a novel process and technology to improve the mechanical, functional and decorative finishes of their current components, or allow the use of alternative (lighter/cheaper) materials (e.g. aluminium, brass, engineered plastics) whilst minimizing hazardous waste and lowering production costs.
