1. Production batch, when the production batch of pressed parts is large, the use of high quality, good wear resistance of the die steel. Should also improve the other process structure parts of the mold and auxiliary structure parts of the parts material. When the batch is not large, the material performance should be specified in order to reduce the cost.


2. The performance of stamping materials for non-standard stamping parts processing and the conditions of use of mold parts. When the stamping material is hard or the deformation resistance is high, the convex and concave die of the stamping die is made of materials with good wear resistance and high strength. When drawing deep stainless steel, aluminum bronze concave die can be selected because of good anti-adhesive properties. Guide pillar guide bush provides for wear resistance and good toughness, so choose low carbon steel surface for carburizing and quenching. Another example is that the main disadvantage of carbon tool steels is poor hardenability. When the cross-sectional dimensions of the die part are large, the central strength after hardening remains low. However, due to its higher impact resistance, it has become an advantage when working on the side of presses with frequent strokes. For fixed and unloading plate parts, not only must they be strong enough, but they are also required to become smaller under working conditions. In addition, CNC machining custom can also choose cold violence and deep cold treatment, vacuum solution and surface strengthening methods to enhance the performance of mold parts. For the convex and concave die working conditions poor cold extrusion die, the choice of strength, strength, toughness, wear resistance of good die steel, with a certain red hardness and thermal fatigue limit.
