Passivation surface treatment for die cast parts

Passivation

Chemical treatment: The use of special solution to remove free iron on the surface of the metal, effectively enhance the surface technology of the workpiece rust prevention.

Electroless nickel plating on die castings

Electroless nickel plating

Electroless nickel plating: A surface treatment process in which nickel-phosphorus alloy is deposited on the surface of the metal through an autocatalytic reaction to significantly improve the wear resistance and anti-corrosion properties of the workpiece.

As machined finish on die cast parts

As Machined

The standard surface treatment can achieve a surface roughness of 3.2 μm (126 μin), effectively removing burrs and sharp edges, ensuring a clean appearance and smooth touch.

Shot blasting finish on die cast parts

Shot blasting

Shot peening: A surface strengthening process that effectively removes the oxide layer and enhances the fatigue strength of the material by blasting abrasive onto the metal surface at high speed.

Spray painting finish on die cast parts

Spray paint

Spraying: High pressure atomized coating and uniform adhesion to the surface of the workpiece, efficient formation of decorative and protective coating surface treatment process.

Sandblasting finish on die cast parts

Sandblast

Sandblasting: A surface pretreatment process that effectively removes the oxide layer and impurities and achieves uniform roughness by blasting abrasives on the surface of the workpiece at high speed.

Anodizing finish on aluminum die castings

Anodizing

Anodizing: A surface treatment process that produces a dense oxide layer on the surface of aluminum through electrolytic reaction, significantly improving the hardness and corrosion resistance of the material.

Electroplating finish on die cast parts

Electroplate

Electroplating: A surface treatment process that forms a metal coating by electrolytic deposition on the surface of the substrate to significantly improve electrical conductivity and corrosion resistance.
