In the raw materials, the current domestic powder metallurgy main raw material has not a single reduction of iron powder, electrolytic copper powder, the domestic has been able to produce atomized iron powder, stainless steel powder, high-speed steel powder, coated powder and various elements of metal MIM powder, Ceramic powder, etc., can basically meet the needs of domestic production of high-strength parts, but also the production of special-purpose raw material powder, greatly expanding the powder metallurgy product varieties, but in quality and variety and abroad there is still a big gap.
In the powder metallurgy equipment, through the introduction of enterprises, the purchase of foreign powder molding press, sintering furnace, mold processing and testing equipment and digestion and absorption, transformation of equipment used to improve product quality and shorten the gap with foreign production level provides a guarantee.
In the powder metallurgy products, has been able to produce high strength, complex shape of the powder metallurgy parts, such as passenger matching timing pulley, motorcycle supporting the use of primary driven gear and other structural parts. However, some, high-grade powder metallurgy parts (such as Buick cars powder metallurgy parts) need to import.
Carry out enterprise joint, reorganization, cultivate large enterprises, large groups, to achieve the scale of operation. Increase technological innovation and scientific research and innovation investment, speed up the new technology, new product development. Improve the mold design and manufacturing level, the application of computer-aided design and manufacturing. Products to high strength, complex shape and special performance of powder metallurgy parts direction. Metal injection molding technology: μ-MIM and 2C-MIM process is currently in the country also began to be applied.
