Process, alloys and envelope
How these parts are usually made
Typical routes for this family. The right process, alloy and limits for your part are confirmed at engineering review.
| Process | Alloys commonly used | Indicative envelope | Typically chosen for |
|---|---|---|---|
| High pressure die casting | ADC12, LM6, LM24 | Across the 280 – 1,250 t range, by housing size; walls from 1.2 mm | Finned housings and heat sink plates at steady volume |
Indicative ranges, not guaranteed values for every geometry. Customer-specific alloys can be arranged on request.
Critical features
What matters on these parts, and how we check it
HPDC holds walls from 1.2 mm, with draft and fin pitch reviewed at design review to protect die life.
Alloy chosen to balance castability and thermal conductivity (for example ADC12 or LM6), agreed at quotation.
Flatness controlled, with machining where the drawing requires it.
Powder coating through a long-standing partner, so housings arrive as finished parts.
To quote this part
What helps us quote accurately
- Drawing or 3D model, with fin geometry
- Required sealing rating and gasket faces, if any
- Finish and colour
- Annual quantity and variants
- Alloy, if specified

Buyer questions
Common questions
Can heat sink fins be cast to shape?
Usually yes on HPDC. Fin thickness, height and draft are reviewed at design review; we suggest changes where a fin would shorten die life or fill poorly.
Which alloy is best for heat transfer?
There is a trade-off between castability and thermal conductivity. We discuss the options for your housing at quotation rather than promise a single value.
Do you deliver coated housings?
Yes, powder coated through a long-standing finishing partner.
