  • Mold material selection conditions (2)

    Strong toughness Most of the working conditions of the mold are very bad, and some often suffer from a large impact load, resulting in brittle fracture. In order to prevent the mold parts from suddenly breaking during work, the mold must have high strength and toughness. The toughness of the mold de... read more

  • Mold material selection conditions (3)

    3. Fatigue fracture performance During the working process of the mold, under the long-term effect of the cyclic stress, fatigue fracture is often caused. The form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The f... read more

  • Mold material selection conditions (4)

    4. High temperature performance When the working temperature of the mold is higher, the hardness and strength are lowered, resulting in early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high anti-tempering stability to ensure that the mold has high h... read more

  • Mold material selection conditions (5)

    Resistance to hot and cold fatigue Some molds are in a state of repeated heating and cooling during the working process, causing the surface of the cavity to be subjected to tensile and pressure-induced stresses, causing surface cracking and spalling, increasing friction, impeding plastic deformatio... read more

  • Requirements for Die Material Selection (6)

    6. Corrosion resistance When some moulds such as plastic moulds are working, due to the presence of chlorine, fluorine and other elements in the plastics, HCI, HF and other strong corrosive gases are decomposed and precipitated after heating, which erode the surface of the mould cavity, increase its... read more

  • Mold material process performance requirements (1)

    Mold manufacturing generally involves several processes such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also ha... read more
