Precious Metal Refining
M&K distinguishes itself with the use of a chemical-based refining process that maximizes the recovery of precious metal scrap materials. Our North Andover, MA facility is certified by a Massachusetts DEP B4 Level III Hazardous Waste Recycling Permi and our processes result in zero discharge, emissions-free, efficient and “clean” recovery, along with quicker turnaround.

Physical Vapor Deposition (PVD)
M&K’s chemical refining process is ideally suited for the cleaning of deposition equipment and the reclamation of precious metals used in PVD processes. Our chemical cleaning process is gentler on tooling than bead blasting which can pit or warp shields thus shortening the life span of a shield kit. In conjunction with our service partner, we also offer surface treatment and coating as well as Class 100 parts cleaning and packaging for direct installation into customers' coating chambers.
