At present, most of the materials used to manufacture 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, high speed Steel, base steel, cemented carbide, steel bonded cemented carbide, etc.
The selection principle of stamping die materials: Based on the comprehensive consideration of its working conditions, stress conditions and properties of the processed material, production batch size and productivity, selecting die materials and implementing the correct heat treatment process is the key to ensuring the life of the die.
In the stamping die, various metal materials and non-metal materials are used, mainly carbon steel, alloy steel, cast iron, cast steel, cemented carbide, low melting point alloy, zinc-based alloy, aluminum bronze, synthetic resin, polyurethane Rubber, plastic, laminated birch board, etc.
The material used to make the mold requires high hardness, high strength, high wear resistance, appropriate toughness, high hardenability, no deformation (or less deformation) after heat treatment, and resistance to cracking during quenching.
Reasonable selection of mold materials and implementation of the correct heat treatment process are the keys to ensuring the life of the mold. For molds with different purposes, comprehensive consideration should be given to factors such as their working conditions, stress conditions, performance of the processed material, production batch size and productivity, and the various properties of the above requirements should be emphasized, and then the steel type and heat treatment should be made. The corresponding choice of craft.
