Material selection requirements for stamping dies

1. The type of material selection of stamping die. At present, stamping die production materials can be roughly divided into: hard alloy, rigid cemented carbide, zinc-based alloy, low melting point alloy, polymer material, aluminum bronze, etc., which realizes the development trend of stamping die forms and material types. Generally speaking, the manufacturing process of stamping die mainly goes through three aspects: die working conditions determination, steel type determination, and processing. In actual processing, in order to determine the rational application of stamping die production materials, it is explored from the level of multiple elements in the stamping die production process. 2. The material selection conditions of stamping die, combined with the material selection conditions of stamping die, the requirements are summarized as: (1) The determination of the applicable environment of the die. As an auxiliary model for the production of automobiles, mechanical parts, etc., the mold is always accompanied by all aspects of actual production. In order to avoid the problem of temporary damage to the mold in the actual use of the mold, when making material selection, it is necessary to make a reasonable choice of mold materials according to the actual application environment. If the mold application environment is high temperature, the material of rigid cemented carbide and cemented carbide can be selected. If the mold is used in a highly corrosive and highly oxidizing environment in the later stage, polymer materials, cemented carbide and other materials can be selected. (2) Precision conditions for mold manufacturing. Stamping die, during the actual production period, should be comprehensively evaluated according to the actual situation of the later stamping product processing. If the stamping die is mainly used for automotive stamping production in the later stage, then the production of the die should be carried out with flexible and flexible materials as the product processing, including zinc-based alloys, low-melting-point alloys, etc. This selection standard is mainly for the convenience of the processing personnel. During the processing and production period, the stamping die can be used for die manufacturing and local die precision processing.
