The production of plastic molds usually requires several technological processes such as casting, cutting production and processing, and heat treatment. In order to ensure the quality of plastic mold manufacturing products and reduce costs, the raw materials should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small air oxidation, Decarburization sensitivity and cracking tendency of quenching deformation.

  • 1. Forgeability: The plastic mold has lower resistance to hot forging deformation, good plastic deformation, wide casting environment temperature range, and low tendency of forging cracking, cold cracking and precipitation of network carbides.
  • 2. Annealing processability: The spheroidizing annealing environment temperature range is wide, the quenching hardness standard is low and the fluctuation range is small, and the spheroidizing rate is high.
  • 3. Machinability: The cutting amount is large, the consumption of CNC tools is low, and the production and processing roughness is low.
  • 4. Sensitivity to air oxidation and decarburization: when heated at high temperature, the anti-oxidation performance is good, the decarburization speed is slow, and it is not sensitive to the heating medium, resulting in a small tendency to black spots.
  • 5. Hardenability: After quenching, it has a uniform and high surface hardness standard.
  • 6. Hardenability: After the plastic mold is quenched, a deeper hardened layer can be obtained, and it can be hardened by selecting the quenching medium.
  • 7. The tendency of quenching deformation cracking: the basic quenching volume change is small, the pattern warpage and distortion are mild, and the tendency of abnormal deformation is low. The basic quenching cracking sensitivity is low, and it is not sensitive to the temperature of the quenching environment and the style of the steel parts.
  • 8. Grindability: The grinding wheel has relatively low loss, no scald, and the maximum amount of grinding is used. It is not sensitive to the quality of the grinding wheel product and the necessary conditions for water cooling, and it is not easy to produce scratches to grinding cracks.
