Powder metallurgy mold

Powder metallurgy has strict requirements starting with the selection of materials. Special steels with high strength, high hardness, good wear resistance and corrosion resistance are usually used. Such materials can withstand high temperature, high pressure and continuous friction of powder particles during long-term use, ensuring the accuracy and service life of the mold.

In terms of design, P/M mold designers must fully consider many factors such as product shape, size, density requirements and production efficiency. For some parts with complex structures, such as gears and camshafts in automobile engines, the design of the mold must be accurate to the smallest corner. Using advanced computer-aided design software, designers can simulate the flow of powder in the mold and optimize the internal structure of the mold to ensure that the powder can fill the mold cavity evenly, resulting in high-quality molded products.

During the production process, powder metallurgy molds show their excellent performance. Metal powder or other powdered materials are placed in the mold, and then a certain pressure and temperature are applied to make the powder particles combine with each other to form parts with a certain shape and strength. This process may seem simple, but it actually requires the mold to be extremely stable and reliable. Pressure control is critical. If the pressure is uneven, it will result in inconsistent product density and affect product performance. The mold temperature control system can ensure that the powder is sintered at the right temperature, making the combination more solid.

With the continuous advancement of technology, we have reason to believe that P/M molds will become more intelligent, efficient and environmentally friendly.
