Sizing & Coining: Reliable Sizing & Coining from Huaxiao
Sizing & Coining are the powder-metal finishing steps that press a sintered part to final tolerance and surface, delivering net-shape accuracy without machining.
How Sizing & Coining Works
A sintered part is re-pressed in a precision die (sizing) or locally deformed (coining) to close pores, sharpen edges, and hit tight dimensions.
Sizing vs. Coining
Sizing corrects overall dimensions; coining forms fine local features like knurls, legends, or calibrated lands.
Materials
- Sintered steel—gears and spacers
- Stainless PM—medical parts
- Bronze PM—bearings
Industries
PM part makers use sizing/coining for final precision.
How to Spec Your Sizing & Coining Job
- Define target tolerances.
- Note features to coin.
- State density after sizing.
- Set surface and edge needs.
- Provide volume.
FAQ
Do I need both?
Sizing is common; coining adds fine features.
How accurate?
Net-shape tolerances, often machined-grade.
