　　Die casting mold factory tells you about the "heat" of die casting mold

　　Die casting mold factory in the production of die casting mold, you need to use a material, called die steel, this is a special steel used to make molds, very suitable for the production environment of die casting processing, die casting mold factory in the use of this kind of steel die casting mold, because the cutting process in the steel internal stress, internal stress will affect the life of the die casting mold, so the need to eliminate internal stress.

　　Die casting mold factory through heat treatment to eliminate internal stress, that is, annealing treatment, quenching treatment, tempering treatment, by heating the material to 600~650 degrees Celsius, you can eliminate 80% of the internal stress, therefore, in the annealing process to eliminate internal stress, die casting mold factory will slowly heat up the die steel to 600-6500C, This temperature is maintained until the central part of the steel reaches this temperature (it takes 1 hour for the steel to be 25 mm thick), and then cooled in the furnace. Die casting die factory can eliminate internal stress by annealing treatment, improve the hardness of the die by quenching treatment, improve the toughness and mechanical properties of the die casting die by tempering treatment.
