Boron nitride nozzles- a solution to solve technical problems from atomization to 3D printing and molten metals

Powder metallurgy has core process advantages such as high material utilization, low unit energy consumption, and environmental protection. It is a technology that is in line with the future direction of carbon neutrality.

In recent years, with the maturity of powder metallurgy technology and the trend of miniaturization of parts, two emerging process routes, metal injection molding (MIM) and 3D printing (AM), have rapidly emerged.

At the same time, the supply of high-quality powder raw materials has begun to become a major factor restricting the development of the industry.

Small and complex parts are undoubtedly more suitable for injection molding and 3D printing (particle size of 20μm or even smaller), and have been increasingly used in high-end fields such as aerospace, medical, electronics, and military industry.

Therefore, the preparation of metal powders with high purity, good sphericity, small particle size and narrow distribution, and low oxygen content has become a new focus in the industry. These parameters have a crucial impact on the quality of metal products.
