Outside suppliers are used for any chemical surface treatments or E coat and powder coat.
Perhaps the best attribute of zinc die castings is the ability to apply almost any kind of surface finish successfully.
E coat, powder coat, paint, chromate, phosphate, chrome plating – zinc castings are able to pass any salt spray or corrosion test easily no matter the coating.
Aluminum castings can also treated with E Coat, powder coat and other coatings as well.
We use certified outside sources for E Coat, powder coat, zinc plate, chromate and chrome plating (both inside and outside spec). In all such cases, coatings are certified by that supplier.
