Description

A rapid cooling powder metallurgy mold

technical field

The invention relates to the technical field of powder metallurgy, in particular to a fast-cooling powder metallurgy mold.

Background technique

Powder metallurgy forming is one of the basic processes in powder metallurgy production. The purpose is to make loose (metal, ceramic, or other materials) powders into semi-finished products with predetermined geometry, size, density and strength by pressure in a mold, and then The semi-finished blank is obtained by demoulding. Compression molding (steel mold) forming is the most widely used forming method in powder metallurgy production. Powder metallurgy has unique chemical composition and mechanical and physical properties, which cannot be obtained by traditional casting methods. The use of powder metallurgy technology can directly make porous, semi-dense or fully dense materials and products, such as gears, etc. Powder metallurgy is a product process that is pressed out with little or no cutting.
