Precautions for Powder Metallurgy Compression Forming

Powder metallurgy technology is becoming increasingly widely used due to its short batch production cycle, low processing and production costs, and the characteristics of minimal or no need for further machining and high precision in batch forming after one-time mold production. So what are the precautions in the process of powder metallurgy pressing and forming?

Precautions for powder metallurgy compression forming:

1. Avoid increasing the cross-sectional area along the compression direction to facilitate compaction. The junction of each wall should be rounded or chamfered to avoid sharp corners, which is conducive to compaction and prevents stress concentration in the mold or billet.

2. Avoid grooves and concave holes on the side walls to facilitate compaction or reduce excess blocks.

3. Try to use simple and symmetrical shapes to avoid excessive cross-sectional changes, narrow grooves, spherical surfaces, etc., in order to facilitate molding and compaction.

4. Avoid local thin walls to facilitate powder compaction and prevent cracking.

The precautions for powder metallurgy pressing and forming are shared here. During the powder metallurgy pressing process, it is crucial to confirm the weight of the product, as unstable pressure in many factories can lead to significant weight differences, which directly affect the performance of the product. The pressed product must be blown off the residual powder and impurities on the surface of the product, neatly placed in the utensil, and prevented from impurities.
