What are the technological properties of precision stamping dies?

Precision stamping dies are equipment that must be used in stamping processing. The quality of the mold is closely related to the workpiece. Therefore, the requirements for the manufacture of precision molds are very strict. In order to ensure the quality of the molds and reduce production costs, the mold making materials should Have certain properties. Forgeability: low hot forging deformation resistance, good plasticity for precision stamping parts, wide forging temperature range, low forging cold cracking and low tendency to precipitate network carbides. Machinability: large cutting amount, low tool loss, and low surface roughness. Annealing processability: wide spheroidizing annealing temperature range, low annealing hardness and small fluctuation range, high spheroidizing rate. Hardenability: uniform and high surface hardness after quenching. Hardenability: After quenching, a deeper hardened layer can be obtained, and it can be hardened by using mild quenching medium. Grindability: The grinding wheel is relatively low in wear, and the non-burn limit grinding consumption is large. It is not sensitive to the quality of the grinding wheel and cooling conditions, and does not cause abrasion and cracks in the grinding precision stamping die. Sensitivity to oxidation and decarburization: when heated at high temperature, it has good oxidation resistance, slow decarburization speed, insensitivity to heating medium, and little tendency to produce pitting. The manufacturing of the mold goes through processes such as forging, cutting, and heat treatment. The processing difficulty is relatively high, and the requirements for manufacturing materials are high. It should have good processing performance to ensure that there are no process defects in the manufacturing process of precision metal stamping molds and the quality is stable.
