Surface Treatment
Passivation
Broadly used in electronic components, passivation is a process by which the imbedded iron
contamination is dissolved and a thin, protective transparent oxide film is formed to increase
corrosion resistance.
Benefits
- Do not change the colour or thickness of the object
- Increase corrosion resistance by removal of surface contaminants
- Cost efficient as electrical current is not required in passivation process.
Nickel / Zinc Plating
Corrosion resistance of products can be strengthened by Nickel/ Zinc plating. Different
sorts of plating have different corrosion resistance ability which can be tested using salt
spray machines.
Benefits
- Improves corrosion resistance
- Enhances illustriousness
- Compliant to RoHS (Restriction of Hazardous Substances)
Zn Nickel Alloy/ Zn Fe Alloy Plating
Benefits
- Superb corrosion resistance
- Achieve more than 1000 hours salt spray test
Electrophoresis
Benefits
- Rich, evenly distributed, smooth coating
- Good coating hardness, adhesion, corrosion resistance and permeation
Spray Painting
Spray painting is a painting technique where a spray gun sprays a coating onto the surface evenly.
Benefits
- For aesthetics purpose
- For identification purpose
- Range of different colours available
Anti-slipping Screws
A thin adhesive put onto the thread to prevent loosening, leakage and vibration.
Benefits
- Resistance to loosening and vibration
- Reusable
