Mechanical Plating & Galvanizing
The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat.
The mechanical plating process takes place in a tumbling barrel filled with tumbling media (e.g. glass beads) which causes the metal powder to be mechanically welded onto the component surface. Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required.
CIP can process parts up to 26” in length and up to 8” in diameter as well as process a maximum of 800 lbs at a time.
Specializing in Mechanical Zinc Plating and Galvanizing
Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum. Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels are highly susceptible.
Additional Post-Plating & Metal Finishing Services
CIP offers two post-plating services: trivalent and hexavalent chromate finishes and sealant finishes. Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.
Mechanical Galvanizing and Plating Specifications & Thicknesses
CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. We also work with both Type I (as coated, without supplementary treatment) and Type II (with chromate conversion treatment) B695 specifications for special processing needs.
