Can West Legacy’s laser engraving service is ideal for applications where finer graphic reproduction is critical. The process begins with a chemical being applied to metal. The metal is then inserted into a computer controlled laser engraver that applies extreme heat to the surface. The heat fuses the chemical to the surface to reproduce the desired image. This fusion is permanent and will last as long as the metal itself. Stainless steel and aluminum are common metals used in the laser engraving process.
