Material

Remark

Heat treatment

Quenching - tempering - nitriding - conditioning - vacuum - deformation etc

Carbon steel - stainless steel - aluminum

Select by Material

Electroplate

Nickel plating - gold plating - chromium plating - zinc plating - silver plating - copper plating

Carbon steel - stainless steel - aluminum - copper

Strong corrosion resistance

Oxidation

General oxygen - hard oxygen - painting - colored

aluminum

Film thickness and color can not be synchronized, easy to have color difference

Spray

Spray powder - spray paint - Spray teflon, etc

Sheet material

Edge size is hard to control

Polishing

Physical polishing - electrochemical polishing - chemical polishing

Stainless steel - aluminium alloy

mirror polish

passivation

acid passivation

Copper - stainless steel

Passivation does not change the color of the product material

The surface treatment of precision workpiece is a very important, which is  related to both the surface effect of the product, and the size of the product. We not only pay attention to the control of internal  production process, but also to the effect of external, so that can better meet the needs of customers.
