Die casting mold factory reminds: if you do not pay attention to this matter, die casting mold must be scrapped

　　In the process of producing die casting die, in order to improve the performance of die casting die, it is necessary to carry out "heat treatment" for die casting die, that is, quenching, annealing, tempering treatment, die casting die factory through these heat treatments can effectively improve the service life and stability of die casting die, which is very helpful to die casting process, but there is a taboo when die casting die heat treatment.

　　Die casting mold factory in the production of die casting, you need to use a special heat-resistant die steel, this steel and ordinary carbon steel, to reach the nose end of the S-curve time is much longer, so this die steel for heat treatment, only need to fully heat through, and then put in the atmosphere to cool, save a lot of things, but die casting mold factory found that, If the die-cast model block made of this material is heated to high temperatures in the air without protection, it will be scrapped due to oxidation and decarbonization or the surface layer is burned out.

　　Therefore, when the die casting mold factory is heat treated for the die casting mold, it is necessary to prevent the appearance of this oxidation and decarburization, for which the die casting mold factory usually buys vacuum furnaces, salt bath furnaces, inert gas (N2 or Ar) furnaces and other equipment, so that as long as the heating temperature is paid attention to, the ideal effect of no oxidation and decarburization can be obtained.
