One-Stop Die Casting Solution
- 01
±0.02 mm on machined features
Tight enough for bearing seats and sealing faces.
- 02
One tolerance stack
No argument between caster and machinist about who is out of spec.
- 03
Faster correction
A drifting feature is fixed at the casting process, not by reworking parts.
- 04
Less handling damage
Parts are not shipped between vendors with exposed machined surfaces.
- 05
Shorter lead time
Machining starts as soon as the castings cool, not after a truck ride.
Applications
Where this capability is usually specified.
Tapped and threaded holes
Threads cut after casting, so pitch, depth and position match the fastener rather than the draft.
Sealing faces and O-ring grooves
Groove width and surface finish controlled to the gasket spec, checked before the part ships.
Bearing bores and seats
Bores machined to press-fit tolerance, measured with a bore gauge and logged per batch.
Flatness and parallelism on mounting surfaces
Datums machined in one setup, so flatness and parallelism hold across the whole face.
De-gating and trimming
Gates, runners and flash removed to the drawing outline, with no nicks left on the parting line.
Assembly-ready sub-components
Machined, cleaned and packed as a kit, so your line receives parts it can bolt straight on.
Frequently Asked Questions
What tolerance can you hold?
±0.02 mm on machined features is routine; ±0.01 mm is possible on small features with the right fixture.
Do I need to specify machining allowance?
Yes — tell us at quoting stage which faces will be machined. We leave 0.5–1.0 mm of stock.
Can you machine parts cast elsewhere?
Yes, provided we can establish a stable datum. Send a sample and the drawing for review.
How is the price split?
Casting and machining are quoted separately, so you can see what each step costs and decide what to keep in-house.
