High pressure die casting · component page
Scooter crankcase and CVT cover
Crankcase halves and CVT covers are large, ribbed, thin walled castings with bearing bores, oil passages and sealing faces. They suit high pressure die casting on larger machines, with careful gating so the ribs fill and the bosses stay sound.
We make two wheeler crankcase halves and CVT covers for Tier 1 suppliers, who machine or assemble them into engines. We do not supply vehicle makers directly.
Process, alloys and indicative ranges
| Process | HPDC on our larger machines |
|---|---|
| Typical wall | 2.5 to 4 mm, indicative |
| Alloys | ADC12, LM24 |
| Supplied | As cast or machined, to the Tier 1 drawing |
Ranges are indicative for this kind of part. We confirm process, machine, alloy and tolerances for your design at drawing review.
Critical features and how we check them
| Bearing bores and dowel holes, when machined by us | Air gauging in house, on every part |
|---|---|
| Internal soundness at bosses and ribs | X ray in house during new component development |
| Sealing faces | Visual inspection in house, at every stage |
| Full dimensional layout | First article inspection on every new tool; CMM through a partner |
Machining and finishing options
- Trimming and fettling
- Machining of bores and faces when in our scope
- Packing that protects sealing faces
Questions that sharpen your quote
- Is the part cast only, or cast and machined?
- PPAP level and submission requirements?
