  • 1、 Longitudinal crack

    The reason for the longitudinal crack is that when the die is completely quenched, the core is transformed into the quenched martensite with the largest specific capacity, thus forming the tangential tensile stress. Moreover, the more carbon content in the die steel is, the greater the tangential tensile stress is. When the tensile stress exceeds the limit of the steel strength, the longitudinal crack occurs.

  •   M42 high speed steel (w2mo9cr4vco8) is a high cobalt resistant high speed steel. It is mainly used for cold stamping dies of precision wear-resistant hardware with high resistance. It can also be used for cutting things and cooling in knives. The steel has high hardness, up to 70hrc, good thermal hardness, high temperature hardness and simple grinding. Cutting things made of this steel

  • Knife path planning
    The principle of tool selection is to consider whether the two-dimensional angle and the three-dimensional angle are too small. After selecting the tool, the next step is to determine the length of the tool, that is, the length of the tool is greater than the depth of processing, and the big workpiece is concerned about whether the chuck will interfere.

  • Fdac die steel is a kind of mold steel which can be directly produced without heat treatment. It has excellent high temperature resistance, wear resistance and corrosion resistance. It can meet the requirements of rapid mold making. The hardness of fdac steel reaches hrc40-44 when it leaves the factory. Even if trace elements are added, the processability is still outstanding

  • The most commonly used cold working die steel is—— Cr12 cold working die steel This kind of die steel is a kind of ledeburite steel with high carbon and high chromium content, which has good wear resistance and hardenability. However, because the carbon content of Cr12 Steel is as high as 2.3%, its impact toughness is relatively poor, it can not bear relatively large impact load, and it is easy to become brittle and crack, and the eutectic carbide formed will be uneven

  • 420 plastic die steel has excellent corrosion resistance, polishing rotation, wear resistance, machinability and stability. After long-term use, the die cavity surface still maintains its original smooth state. As long as it is operated or stored in a humid environment, it does not need special protection. And its production cost is relatively low. 420 plastic mould steel is suitable for all kinds of plastic products
