What is the process of powder metallurgy? With the ongoing development of new manufacturing techniques and equipment, powder metallurgy has become a crucial part of modern industry. The production process in powder metallurgy can be broken down into five key stages: powder production, mixing, forming, sintering, and post-processing.

This process involves converting raw materials into metal powders. Common methods for powder production include oxide reduction, atomization, electrolysis, rotating electrode, and mechanical milling.

Heat treatment refers to a metal thermal processing technology that changes the chemical composition and structure of the surface or interior of a material by heating, heat preservation and cooling in a solid state to obtain the desired properties. Heat treatment generally includes three processes: heating, heat preservation and cooling, and sometimes only two processes: heating and cooling.

Whether the design of stamping die is reasonable is the basis of improving the durability of stamping die. Therefore, when designing stamping dies, effective measures should be taken against adverse conditions in product forming, which aims to improve the durability of the stamping die. 

Mold is known as the "mother of industry", and 3D printing directly manufactures products without mold over the mold manufacturing process, it seems to be an alternative relationship between them, but the answer is not.

The development of modern manufacturing industry can’t be separated from the mold, this article will introduce the six basic knowledge points to help you better understand this field.
