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
