Mechanical plating, also known as zinc plating, is a corrosion-resistant coating that is formed in a non-electrolytic and non-thermal process - ideal for hardened products.
In a fully automated process, zinc powder and glass beads are added to the products in a rotating drum, under the right chemical atmosphere. The chemical reaction ensures adhesion and the beads roll the zinc powder onto the products, creating a very even zinc layer. Afterwards, the products can be treated as required with passivation, torque & tension oil (T&T) and sealer.
The functional properties of mechanical plating are more topical than ever:
- Zero defects due to a controlled process and exclusion of adhesion
- There is no risk of hydrogen embrittlement;
- Very even layer thickness;
- Cold process does not affect material properties;
- Good electrical emergency conductivity;
- Suitable for fastening materials and other metal parts (threaded or non-threaded); hardened products, spring steel, bolts, nuts, washers and wire nails, among other things
The process meets the NEN-EN ISO 12683 and ASTM-B 695 standards.
