Materials for making stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloys, low melting point alloys, aluminum bronze, polymer materials and so on. At present, most of the materials used to make stamping dies are steel. The commonly used types of die working parts are: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, Steel, base steel, cemented carbide, steel bonded cemented carbide, etc. To
The materials used in the stamping die can be various metal materials or various non-metallic materials. The two types of materials mainly include carbon steel, alloy steel, cast iron, cast steel, cemented carbide, and low melting point alloys. , Zinc-based alloy, aluminum bronze, synthetic resin, polyurethane rubber, plastic, laminated birch wood, etc.
The requirements for the materials used to make the mold are also very strict. Not only are the materials required to have high hardness, strength and wear resistance, but also appropriate toughness, as well as high hardenability, and non-deformation during heat treatment and resistance to cracking during quenching.
In order to ensure the service life of the mold, a reasonable selection of mold materials and the correct implementation of the heat treatment process must be carried out. The selection of the correct steel grade and heat treatment process should correspond to the different uses of the mold. In addition, it should also be based on its working status, stress conditions and properties of the processed material, production batch size and productivity, etc., and should focus on the above descriptions. The performance of the various requirements.
