Surface Treatment and Finishing of Plastics and Metals

Why is surface treatment so crucial? It matters because untreated surfaces are fragile. As a result, they often look low-cost, tend to accumulate dust, and are susceptible to mechanical damage.

Advantages of Surface Treatment

  • Higher wear resistance and scratch resistance
  • Enhanced resistance to chemicals and ultraviolet (UV) radiation
  • Improved adhesion for paints, adhesives and printing inks
  • Creation of an appealing appearance through glossy, matte or textured effects
  • Functional properties such as electrical conductivity or non-stick surfaces

Surface Treatment Processes We Offer

1. Machining

  • Grinding and Polishing: Used to achieve smooth and glossy surfaces.

Sandblasting/120mesh:

  • (including sand blasting, glass bead blasting or dry ice blasting): Applied to create matte, textured finishes or for surface cleaning.

PVD/CVD Vacuum Coating:

  • Deposits a nano-scale film on metal surfaces via physical or chemical vapor deposition. Delivers metallic textures and iridescent gradient effects while improving hardness and wear resistance. Suitable for cutting tools, jewelry, and high-end electronic components.

Etching/Laser Engraving :

Nanoimprint Lithography(NIL)
  •  Forms precise patterns, text, or hollow structures via chemical etching or laser ablation. Offers high precision and artistic appeal. Used for circuit boards, metal crafts, and identification signs.
