Powder Metallurgy Compacting FAQs

In powder metallurgy process, compacting pressures vary depending on the metal type and the desired characteristics of the part.

For instance, softer metals typically require pressures between 200 and 400 MPa to ensure effective compaction.

Harder metals such as steel demand higher pressures, ranging from 400 to 800 MPa.

To reduce porosity, optimizing particle size distribution and compaction parameters is crucial. Using techniques like HIP can significantly enhances the diffusion process of bonded metal particles, thereby reducing porosity.

Taking the data only as an example of a 25-ton fast-speed compacting machine, the product is in the shape of a round barrel:

Japan compacting machine: 50~60pcs/min.

German compacting machine: 40~55pcs/min.

American compacting machine: 40-50pcs/min.

China compacting machine: 30~40pcs/min.

Data is for reference only!

Yes, if done improperly, there is a risk of the mold exploding, eventually causing personal injury. But if you strictly follow the work instructions, this problem can be avoided.

The key depends on the size of the production. Buckets are generally divided into:

• 100kg
• 250kg
• 500kg
• 1000kg
