Electroless nickel plating is one of the few surface treatments with truly even coverage. Deep holes, threads, and internal passages all receive full coating. Instead of electrical current, the process uses an autocatalytic chemical reaction. It builds a uniform nickel-phosphorus alloy wherever fresh chemistry can reach. Conventional electrolytic plating would

Metal polishing transforms a machined surface from functional to flawless, whether the target is a soft satin sheen or an optical mirror. Unlike coatings, polishing removes a thin layer of material to erase tool marks, scratches, and pits, revealing fresh metal underneath. The trade-off is labor: polishing remains one of

A bead blasting finish is one of the fastest ways to turn a raw CNC part into a clean, consistent product. The process propels millions of tiny media particles at the surface, peening away tool marks and leaving a uniform matte satin texture. Because the equipment is simple and cycle

Stainless steel earns its name from a chromium oxide film that shields the iron underneath. Yet machined stainless parts can still rust, and the culprit is usually the machining process itself. Stainless steel passivation removes that contamination and restores the protective layer, making it one of the most valuable low-cost

Anodizing aluminum parts is the most common way to protect and decorate CNC machined aluminum. The process grows a controlled oxide layer on the metal surface, adding corrosion resistance, hardness, and color while contributing almost no weight. Because aluminum already carries a thin natural oxide film, anodizing simply thickens that
