Large-scale production of plastic, synthetic resin and rubber requires a homogeneous and uniform tool quality provided by SIMOLD tool grade steel.


The SIMOLD group of steel is heat treated to the required working range of hardness, which significantly shortens the time it takes to make these tools since no final heat treatment is required. There is also no risk of dimensional changes of tools and of cracking due to heat treatment.

The main features of the SIMOLD brand tool steel for plastic moulding:

  • Microcleanliness - high purity steel
  • Polishability
  • Machinability (sulphur alloyed steel)
  • Temperature resistance
  • Wear resistance
  • Dimensional stability
