Advantages and disadvantages of powder metallurgy

Powder metallurgy is an industrial technology for making metal powder or taking metal powder as raw material, and then processing, forming and sintering to make metal materials, composite materials or other types of products. What are the advantages and disadvantages of this technology? What are the advantages and disadvantages of powder metallurgy?

Advantages and disadvantages of powder metallurgy

1、 Advantages of powder metallurgy

1. Preferred molding technology for production of complex parts

Powder metallurgy is the preferred advanced molding technology for complex precision parts in various fields. Non ferrous and nonferrous metals, large size, small size, and various types of materials cannot defeat powder metallurgy molding technology.

2. Preferred forming scheme for spare parts

No matter in the fields of aviation, underground pipeline transportation, petroleum industry, automobile and medical equipment, powder metallurgy is called the preferred metal forming technology solution.

3. Longer service life

Powder metallurgy molding technology extends the service life of processing parts by increasing the reliability of components, so powder metallurgy is also known as the preferred metal molding scheme at present.

4. Make impossible possible

Many complex and precise spare parts can not be completed by traditional molding process, but powder metallurgy makes these impractical problems possible: and the performance is more stable.

5. Complex parts can be processed in large quantities

Powder metallurgy molding technology can process and produce complex parts and components in large quantities. Due to less cutting and no cutting in the molding process, the waste of materials is greatly reduced. The formed parts and components are very similar, and it is not easy to form scrap. Therefore, there are few powder metallurgy processing steps, high material utilization rate, and easy molding, so the powder metallurgy processing cost is relatively low.

6. Reduce the production of processing and waste

Powder metallurgy molding technology is a net near molding technology, which can reduce manufacturing steps, no cutting, less cutting, reduce processing, reduce waste generation. There is almost no waste in the molding process of various types of gears, and the utilization rate of steel resources is very high.

2、 Powder metallurgy disadvantages

1. The effective time limit of oil lubrication for the processed oily gear teeth is relatively short, so external lubrication shall be considered.

2. Powder metallurgy is suitable for processing large batches of complex parts. If the batch of parts is less than 6000 pieces, the cost is higher than that of traditional molding technology.

These are the advantages and disadvantages of powder metallurgy, which may not be understood by many people. But after Zhongwei's precise introduction, we should have a further understanding of powder metallurgy. It can be seen from these contents that the advantages of powder metallurgy outweigh the disadvantages. For the production of some precision spare parts, powder metallurgy processing technology is still the mainstream production and processing technology
