Metallization

The metallization process consists in the coating of parts through the projection of zinc.

The process begins with shot blasting the parts to create the roughness (SA 2 1/2) required for zinc to easily adhere to the parts. In our metallization process we use the electric arc process where 2 zinc wires are charged with opposite currents and when touching in the gun they fuse, then compressed air is used to diffuse the molten zinc particles to treat the workpiece.

This process over other used ones has the advantage of not being thermally aggressive which produces very little warping on the parts.
