[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. The materials used to make stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer materials, and so on. The vast majority of materials used to make stamping dies are steel-based. Commonly used materials for the working parts of the mold include: carbon tool steel, low alloy tool steel, high-carbon and high-chromium or medium-chromium tool steel, medium-carbon alloy steel, high-speed steel, matrix steel, cemented carbide, steel-bonded cemented carbide, and so on.
