What kind of steel is better for making molds

In the manufacturing industry, the mold is a crucial part. They are the tools that transform materials into finished products and play a decisive role in the quality, accuracy and cost efficiency of products. One of the key factors that determine the performance of the mold is the choice of steel. So, what kind of steel is better for making molds? This article will explore this issue in depth and reveal the mystery of mold steel selection for you.

First, the selection standard of mold steel

When choosing die steel, the following factors need to be considered:

1. Hardness: The mold needs to withstand a lot of pressure and friction during use, so it needs to have high hardness to ensure its durability and life. In general, the hardness of the mold steel should be between HRC30-55.

2. Toughness: the mold may have fatigue, fracture and other problems during use, so it is necessary to have a certain toughness to prevent this from happening.

3. Wear resistance: During the use of the mold, due to long-term friction, it will lead to the wear of the mold. Therefore, the die steel needs to have a certain wear resistance.

4. Heat resistance: In high temperature environment, mold steel needs to have high heat resistance to prevent mold deformation due to high temperature.

5. Thermal conductivity: The mold will generate a lot of heat during processing, so it needs to have good thermal conductivity to facilitate the rapid transfer of heat.

Second, common mold steel

1. Cr12MoV: This is the most commonly used mold steel in China, which has good comprehensive properties and is suitable for all kinds of cold working molds. Its hardness is between HRC52-56, with high toughness and wear resistance.

2. SKD11: This is a mold steel imported from Japan, which has good heat resistance and wear resistance, and is suitable for large, complex and high-precision molds. Its hardness is between HRC52-56.

3. D2: This is a mold steel imported from the United States, with high hardness and wear resistance, suitable for molds with high wear resistance requirements. Its hardness is between HRC60-62.

Third, the selection method of mold steel

In the selection of mold steel, should be based on the use of the mold environment, service life, precision requirements and other factors for comprehensive consideration. For example, for molds with high service life requirements, steel with high wear resistance and heat resistance should be selected; For molds with high precision requirements, steel with high hardness and good toughness should be selected.

In SUMMARY:

The choice of mold steel is a complex process, which needs to be comprehensively considered according to the use environment, service life, precision requirements and other factors of the mold. Only by choosing the right steel can we make a mold with good performance, thereby improving the quality and efficiency of the product. I hope this article can provide you with some reference and help when choosing mold steel.
