The mold when in use basically the temperature is relatively high, so the mold must have certain ability of anti high temperature, can withstand the pressure. The use of steel for mold will also have strict requirements, to ensure that the overall performance of mould.
  1, mold the need for heat treatment process, improve its hardness, ensure that there is more thick ah stiffness. Because when the mold use may be influenced by the pressure and friction is large, must ensure the mold shape and size precision stability, can ensure that the mould can be used for a longer time. And the influence of wear resistance of the mold is greatly is influenced by the chemical composition and the heat treatment of steel hardness, so when the mold hardness increases, it will have more excellent wear resistance.

  2, cutting has a long influence on the performance of the mold, in order to make the cutting tool can be used longer, to ensure good cutting performance and reduce the roughness, in the mold must use the appropriate steel.

  3, the use of steel in the mold must be polished properly, make its surface more smooth, not too many impurities in steel, in polishing when not pitted and orange peel appearance etc..
The performance of steel mold mold will have great influence, therefore must pay attention to the choice of steel, to ensure that the mold can be used for a long time.
