Centrifugal casting spins a mould while metal is poured, so centrifugal force throws the metal against the wall. It yields dense, sound cylindrical parts.
At a glance
When to use it, and when not
Best for
Pipes, rings, bushings and sleeves where a dense, defect-free wall matters.
Watch for
Limited to axially symmetric shapes; the bore finish needs machining.
Step by step
The typical route
Raw material to finished part. Steps vary with material, volume and tolerance; this is the free route from the finder.
Spin up
Pre-heat the mold and bring it to speed.
Tooling Spin mold Tolerance - Lead -
Pour
Pour metal into the spinning mold; force packs it to the wall.
Tooling Furnace Tolerance - Lead -
Extract
Stop, cool, and withdraw the casting.
Tooling - Tolerance - Lead -
Machine ID/OD
Machine the bore and faces; the inner surface is rough as-cast.

UT inspect
Ultrasonic test rings/pipe for soundness.

Cost
What it costs
Dense, sound round parts (rings, bushings, pipe); ID is machined since the inner surface is rough.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for your part at your volume, in your currency, are in the dossier.

Centrifugal casting spins a mould while metal is poured, so centrifugal force throws the metal against the wall. It yields dense, sound cylindrical parts. The typical route is: Spin up; Pour; Extract; Machine ID/OD; UT inspect. Pipes, rings, bushings and sleeves where a dense, defect-free wall matters.
What does Centrifugal Casting cost per part?
It depends on size, tolerance and volume. As a rough ballpark it starts around $265 to 750 per part at low volume and falls with quantity. The dossier gives should-cost at your exact volume and currency. Model estimates, not quotes.
What tolerance can Centrifugal Casting hold?
Typically about +/-0.3 mm, tighter with extra finishing operations at higher cost.
What materials suit Centrifugal Casting?
Common choices are Bronze/brass (Bearing surfaces); Cast iron (Cheap, damping); Stainless/duplex (Corrosion).
