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.
Maximum Part Size: Ø8" x 26"
Maximum Load Size: 800 lbs*
*dependent on part size/shape
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.
