What is the difference between powder metallurgy processing and CNC processing?

In recent years, the development trend of powder metallurgy has been very strong, especially in the automotive field, where over 90% of spare parts are processed using powder metallurgy. So many people like to compare powder metallurgy and CNC machining. What are the differences between powder metallurgy and CNC machining?

The advantages of powder metallurgy processing:

1: Low processing cost

For products with very complex shapes such as gears, powder metallurgy processing technology is easy to form and can be mass-produced. The production cost is lower compared to traditional processing industries, and the accuracy is higher. Therefore, the application of powder metallurgy in the processing of automotive parts is increasing.

2: Prepare more complex materials

Powder metallurgy processing can prepare materials that are difficult to prepare by other processing methods, such as fake alloys, porous metal materials, insoluble metal materials, hard alloys, etc. Powder metallurgy processing can achieve better results.

3: Save materials

Powder metallurgy is a new type of net close forming processing technology that uses the same mold as the final product for forming, thereby reducing machining, material consumption, and cost.

4: Uniform composition ratio

Powder metallurgy processing technology can ensure the uniformity and correctness of the composition ratio of processed materials, ensuring the performance of products.

Advantages of CNC machining:

1: High production efficiency

For parts with multiple varieties and small batch sizes, CNC machining can reduce time and increase production efficiency compared to traditional machining.

2: Stable processing quality

The quality of parts processed by CNC machining is stable, the machining accuracy is relatively high, and the quality of processed parts is relatively stable.

3: High precision and high rigidity

The precision and rigidity of CNC machine tools are high, and favorable processing quantities can be selected, which is five times higher than the production efficiency of ordinary machine tools.
