The selection and performance enhancement of stamping die materials are critical to the quality and efficiency of the manufacturing process. Correct selection of stamping die materials can improve productivity and reduce costs, and the selection should take into account factors such as the material, quantity, shape, size and surface quality requirements of the parts to be produced. In this paper, we will discuss issues related to the selection and performance enhancement of stamping die materials.

Firstly, the selection of stamping mould materials should be based on the stamping process and the requirements of the stamped parts. For example, for the blanking process, materials with good toughness and wear resistance should be selected, such as high-speed steel, alloy tool steel, cemented carbide and so on. For deep drawing process, materials with good plasticity should be selected, such as aluminium and aluminium alloy, brass, low carbon steel, etc. For the moulding process, elastic materials should be avoided to ensure the angle stability.

Secondly, the performance enhancement of stamping mould materials can be achieved through methods such as surface treatment and heat treatment. For example, Maxima coating can increase the wear resistance and lubricity of the die, and nitriding treatment can improve the stamping roughness and adhesion, thus prolonging the service life of the die. In addition, the use of lubrication pads such as Eliminator™ can keep the punch edge lubricated at all times, and a soft oil stone (STO29911) can be used to remove burrs from the punch edge.

Finally, proper use and maintenance of the mould will extend its life. Regular inspection, correct use of lubricant and proper storage can extend the service life of the die.

In summary, the selection and performance enhancement of stamping die materials are critical to the quality and efficiency of the manufacturing process. Correct selection of stamping die materials and enhancement of their performance through methods such as surface treatment and heat treatment can extend the service life of the die, improve productivity and reduce costs.
