In general, the factors that have a great influence on the life of the Powder Metallurgy Mold include: the structural design of the mold, the selection of the female mold, the mandrel and the punching material, the quality of the heat treatment, and the quality of maintenance and repair. At the same time, the type and performance of the powder, the shape and density of the product, etc., will also have a certain degree of influence on the life of the powder metallurgy stamper.
In fact, for a particular type of powder metallurgy part, the choice of materials and the quality of the heat treatment of the parts are the most important factors affecting the life of the Powder Metallurgy Mold. In order to extend the service life of the mold, it can be considered from two aspects: one is to improve the heat treatment process and give full play to the potential of the existing materials; the other is to select new materials to improve the life of the mold.
Of course, there are many factors affecting the life of Powder Metallurgy Mold, and the selection of heat treatment process and materials are two of the main factors. Solving these two problems, the service life of the powder metallurgy stamper will be doubled, and the production cost will be greatly reduced, which not only can fully exert the significant advantages of the powder metallurgy process and no cutting, but also the economic benefits are obviously improved.
