PM VS Casting and Stamping
Powder metallurgy is progressively replacing traditional casting and stamping methods due to its superior speed and cost-effectiveness. This manufacturing process utilizes metal powders, including recycled waste from metal production, to create components with high durability and wear resistance. Through sintering, parts can be formed with precise geometrical accuracy, typically eliminating the need for additional machining.
The production technology involves placing metal powders into specialized molds where they undergo thermal treatment in a controlled gas atmosphere. This treatment enhances material plasticity and facilitates the integration of special polymers. Subsequent processes including pressing, rolling, and forming enable the metal powder particles to fuse into a monolithic structure. Finally, thermal treatment in specialized furnaces imparts the necessary hardness and wear resistance to the finished components.
