Surface Finishing & Secondary Processes
Painting
Industrial painting applies a smooth, protective coating designed to enhance chemical resistance and weatherability. Available in custom RAL colors and finishes (gloss, semi-gloss, matte), making it ideal for large enclosures, machine components, and cosmetic surfaces.
Powder Coating
Powder coating delivers an exceptionally thick, durable, and impact-resistant protective layer compared to traditional liquid paint. It cures under heat to form a seamless finish with excellent chip, scratch, and corrosion resistance for rugged metal parts.
Electroplating
Electroplating deposits a thin layer of functional metal (such as Gold, Silver, Nickel, Chrome, or Brass) onto components via electrolysis. It significantly improves electrical conductivity, solderability, wear resistance, and oxidation protection for precision electronic and slip ring parts.
Passivation
Passivation is a specialized chemical treatment for stainless steel that removes free iron and surface contaminants. It restores the natural chromium oxide passive layer, preventing rust and ensuring biocompatibility and cleanliness for medical, food, and aerospace applications.
Sandblasting
Sandblasting utilizes high-pressure airflow to spray fine abrasives across the workpiece, effectively removing burrs, machining marks, and surface oxidation. It produces a uniform matte or satin texture, perfect as a final aesthetic touch or base layer for subsequent plating and coating.
Anodizing
We specialize in high-precision anodizing for aluminum, titanium, and magnesium components. Anodizing provides exceptional corrosion resistance, surface hardness, and a sleek aesthetic finish in various colors without compromising tight dimensional tolerances.
