Surface Treatment

Top

• Hardening and Tempering
  Produce the most durable parts with clean surfaces and minimum distortion
  
  
• Stress Relieving
  Release surface stress induced by rough machining, welding, electric discharge machining (EDM), or accumulated during extended service, especially for die casting dies
  
  
• Oxidizing
  Form a surface layer to protect the cavities of aluminium die casting dies from erosion and corrosion attack
  
  
• Subzero Processing
  Enhance wear resistance and minimize the amount of retained austenite to ensure that tools are highly stable
