Plastic Mould Steel

Pre-hardened plastic mould steels are widely used for manufacturing mould for plastic because of their four main properties and characteristics:

  • Wear Resistance
  • Corrosion Resistance
  • Mirror Finishability
  • Surface Workability

These steels are quenched and tempered before being manufactured into mould for plastic, therefore the deformation and cracking of mould resulted from heat treatment can be avoided.

General Applications:-
  • Plastic Mould Industry
  • Mould Frames
  • Machine Tool Engineering
  • Die Casting Industry
  • Mould Parts
  • Preform Dies
