Stamping dies are important tools for manufacturing various parts such as automobiles, home appliances, and electronic equipment. The quality and service life of the mold directly affect the quality and production efficiency of the product. Therefore, choosing the right steel is crucial for the manufacture of stamping dies. First of all, the steel for stamping dies needs to have high hardness, high strength, high wear resistance and high toughness. Commonly used steels include tool steel, alloy structural steel, high-speed steel, etc. Among them, tool steel is one of the main materials for stamping dies because it has high wear resistance and hardness and can withstand large extrusion force and impact force. Alloy structural steel has high strength and toughness and is suitable for manufacturing large and complex stamping dies. High-speed steel is suitable for manufacturing high-speed stamping dies because it can withstand higher temperatures and pressures.

Secondly, the steel of the stamping die also needs to have good processing properties and heat treatment properties. Processing performance includes cutting performance, thermal stability and weldability, etc., which directly affect the manufacturing cost and quality of the mold. Heat treatment properties include quenching hardening properties, tempering stability and deformation resistance, etc., which can ensure that the mold is not easily deformed and damaged during use.

Finally, the cost and availability of steel for stamping dies also need to be considered. Although high-end steel can improve the quality and life of stamping dies, the cost is also relatively high. Therefore, when choosing steel, you need to consider the balance between cost and performance, and choose the steel that suits your business.

To sum up, choosing the right steel is crucial for the manufacture of stamping dies. When selecting steel, factors such as hardness, strength, wear resistance, toughness, processing performance, heat treatment performance, cost and availability need to be comprehensively considered to achieve the best manufacturing results and economic benefits.

What steel is used for stamping dies?

The materials used to manufacture stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloys, low melting point alloys, aluminum bronze, polymer materials, etc.

Most of the materials used in manufacturing stamping dies are steel. Commonly used materials for mold working parts include: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, and high speed steel. , base steel and cemented carbide, steel-bonded cemented carbide, etc.

When the forming conditions cannot be met, the hot stamping forming technology of ultra-high strength steel plates is gradually studied internationally. This technology is a new process that combines forming, heat transfer and structural phase transformation. It mainly uses the characteristics of increased plasticity and reduced yield strength of sheet metal in the high-temperature austenite state to form through the mold.

Process nature categories of stamping molds:

a. Blanking die: a die that separates materials along a closed or open contour line. Such as blanking dies, punching dies, cutting dies, incision dies, trimming dies, slitting dies, etc.

b. Bending mold: A mold that causes the sheet blank or other blanks to bend and deform along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

c. Drawing die: It is a die that converts sheet blanks into open hollow parts, or allows the hollow parts to further change their shape and size.

d. Forming mold: It is a mold that directly copies the blank or semi-finished workpiece according to the shape of the convex or concave mold, and the material itself only produces local plastic deformation. Such as bulging mold, shrinking mold, expanding mold, undulating mold, flanging mold, shaping mold, etc.
