In raw materials, powder metallurgy at home and abroad, the main raw material is not only reduced iron powder, electrolytic copper powder, etc., China has been able to domestic production atomized iron powder, stainless steel powder, high speed steel powder, coating powder and various elements MIM metal powder, ceramic powder, etc. Basically this can meet the needs of the domestic production of high strength parts, also can produce special purpose raw material powder, greatly expanded the powder metallurgical products, but there is still a large gap with abroad in quality and variety.
In powder metallurgy equipment, through the enterprise introduction, purchase and use foreign powder forming press, sintering furnace, mold processing and testing equipment, digestion, absorption and transformation equipment, this provides the guarantee of improving the product quality, and shortening production level gap with foreign countries.
In powder metallurgical products, we can produce high strength and complex powder metallurgical parts, such as car matching wheel, motorcycle matching with primary driven gear and other structural parts. However, some of the high grade powder metallurgical parts (such as the Buick powder metallurgical parts) are also imported.
Enterprises should be jointly and reorganized to cultivate large enterprises and large groups to achieve scale operation. We will increase investment in technical reform and research and innovation, and accelerate the development of new technologies and products. Accelerate new process and new product development. Improve mold design and manufacturing level, apply computer aided design and manufacturing. The products are developed in the direction of high strength, complex shape and special performance powder metallurgy parts. Metal injection molding new technology: μ-mim and 2C – MIM processes are also being used at home.
