Metal finishing of our precision metal stamped components include surface treatments such as cleaning, passivation, tumbling, deburring, bright dipping, bead blasting, sand blasting, and anodizing. Some of the plating’s we offer include Copper, Nickel, Zinc, Tin, Silver, and Gold, as well as oxide phosphate and e-coating, and custom coloring of zinc coatings.
