Powder Metallurgy Sizing FAQs

Learn how sizing improves dimensional accuracy in powder metallurgy. This FAQ covers labor costs, die design, and how sizing presses differ from compacting presses.

Sizing in Powder Metallurgy

Workers handle about 10 to 15 parts per minute. In China, the monthly salary of an average worker is approximately $550 to $620. The labor cost for sizing a part is about $0.04 to $0.11. So, sizing is an economical way to achieve tighter component tolerances.

No.

The dies for sizing are not the same as those used in the compaction.

Compaction process dies have more complex shapes.

Sizing dies often corrects the size of a single dimension of the part. They are specifically designed to attain precise tolerances for parts.

No.

Compacting presses operate at higher tonnages because they need to press the metal powders into a dense, coherent mass.

Sizing presses make small dimensional adjustments to the parts, so the force applied does not need to be as high.
