福建Advantages of powder metallurgy summarized after business

When I came back from this business trip, I knew more about the advantages of powder metallurgy parts. Many foreign manufacturers set up their procurement and production bases in China, which can avoid high personnel, companies and material costs. Even if the foreign processing is sent to China, the cost is less than that of their own processing. Powder metallurgy is used in a wide range of fields. Usually, it is assumed that there are many cars. But with the continuous updating of powder metallurgy technology, Powder metallurgy parts in various fields have also risen. The following are some of the powder metallurgy advantages summarized from business trip.

Advantages of Powder Metallurgy

1. First, the selectivity of raw materials is relatively large. For example, the prices of iron, carbon, copper, nickel and other raw materials are different. At present, the price of iron has risen to more than 7000 per ton, and powder metallurgy technology can use 100% raw materials.

2. For new parts production varieties, the investment in powder metallurgy is far lower than that in other production methods.

In view of this technical and economic characteristics, the environmental pollution of cast iron castings has always been a thorny problem. A large number of small cast iron parts used in automobile manufacturing in North America, Japan and Western Europe have mostly become powder metallurgy parts. A prominent example is the valve tube part. This part has not only casting problems, but also processing problems, especially the processing of slender holes.

3. When using powder metallurgy to produce parts, the process of powder metallurgy is simple, which can save a lot of technological processes. Saving various processes can save the cost of enterprises and greatly reduce the consumption of manufacturing parts. In particular, parts such as powder metallurgy machine with complex structure can achieve energy-saving effect.

4. For powder metallurgy technology parts manufacturers, environmental pollution is more environmentally friendly than traditional production parts. Environmental protection has always attached great importance to. Enterprises cannot afford not to add pollutants to the ecosystem. At the same time, powder metallurgy does not contain toxic substances. A good working environment is conducive to avoiding physical and mental, noise and air pollution of workers and reducing personnel loss.

5. Lianyungang Dongmu New Materials Co., Ltd. has two major powder metallurgy technologies, namely, traditional powder metallurgy metal pressing and MIM metal injection molding. It is currently the largest powder metallurgy manufacturer in China, and the only enterprise in the world with PM and MIM industries of more than 1 billion at the same time. It is very suitable for manufacturing complex forms of parts that can not be manufactured by any cutting method. The combination of complex P/M tools is small in size and complex in process, which is suitable for P/M technology.

6. When producing parts, in addition to grinding, the surface roughness of mechanical parts manufactured by powder metallurgy technology is good, which can reach 0.8 roughness. In addition, the dimensional tolerance accuracy that can be achieved in the radial direction is only inferior to grinding.

7. The difficulty in the early stage of powder metallurgy production lies in the development and investment of molds. The higher the output of parts, the more production, the greater the cost savings. For example, for automobile powder metallurgy products, if the automobile itself belongs to the field of mass production, take powder metallurgy sprocket or powder metallurgy gear as an example.

8. It can control the porosity of products and produce various oil bearings and porous materials. With the characteristics of large specific surface, high density and low conductivity, the application scope of metal materials has been greatly expanded in catalysis, filtration, heat transfer, sound insulation and other situations.

9. The powder metallurgy process can utilize the combined effect of metal and metal, metal and nonmetal to produce various materials with special properties, such as electrical contact materials composed of copper and alloy, friction materials composed of metal and nonmetal.

10. Powder metallurgy technology can produce various composite materials, including hard alloy and cermet composed of insoluble compounds and metals, dispersion reinforced composites, fiber reinforced composites, etc. 11. For powder metallurgy gears specially needed, the performance of high alloy powder metallurgy materials is better than that of casting methods. For example, powder high-speed steel and powder superalloy can prevent the deviation of size and composition, greatly improve the hot workability through microcrystalline lip structure, and ensure the uniform structure and stable performance of alloy parts.

12. The production of hard to dissolve metal materials or products generally depends on powder metallurgy (such as tungsten, molybdenum and other hard to dissolve metals), which can be produced by smelting, but the particles are coarser and lower in purity than those of powder metallurgy products.
