Powder metallurgy mold

A mold used to press metal powder or non-metal powder into shape. Powder metallurgy is the preparation of a powder mixture as raw material, which is pressed and formed by a four-beam and four-column hydraulic press with a powder metallurgy mold, followed by high-pressure forming and sintering to form a finished product with the shape and size required by the mold used.

The basic principle

Give full play to the process characteristics of less powder metallurgy, no cutting processing and near-forging to ensure that the blank meets the three basic requirements of geometric shape and size, accuracy and surface roughness, density and distribution.

The product uses high-strength mold steel, which is solid and durable in use, not easily deformed, and improves service life. At the same time, the design and manufacturing process of powder metallurgy molds are demanding. Computer technology is required to design the model, the design is reasonable, and CNC milling machines are used for finishing. The surface of the mold is smooth and durable, and the processed powder products have high precision and high density.

Advantage

1) During the manufacturing process of the product, the metal powder undergoes processes such as mixing, pressing and sintering, which can uniformly distribute the composition and structure of the material and improve the uniformity and consistency of the material.

2) The product has good processing performance, and can achieve the required mold shape and performance through heat treatment, mechanical processing and other processes.

3) Suitable for the production of high quality, special shape, refractory metal, large volume, less than 10 kg, and complex structural parts.
