What we cast, and what each industry asks of it
The same 1,250 tonne cell makes an EV inverter housing in the morning and a telecom heat sink in the afternoon. What changes is not the machine but the acceptance criterion, and that is the thing worth agreeing on before tooling starts.
| Industry | Typical parts | The acceptance criterion that matters |
|---|---|---|
| Electric vehicles | Battery tray frames, motor and inverter housings, structural nodes | Leak tightness after machining and X-ray acceptance in the load path |
| Powertrain and transmission | Clutch and transmission housings, covers, bearing retainers | Bore geometry, face flatness and a documented capability study |
| Industrial equipment | Pump and gearbox housings, frames, mounting brackets | Dimensional repeatability over long production runs |
| Telecom and power electronics | Heat sinks, RF housings, enclosures | Fin fill and flatness at the thermal interface |
| Lighting and consumer hardware | Lamp housings, bezels, decorative frames | Surface finish and colour consistency after coating |
If your part sits in two columns at once, the stricter criterion wins, and it should be written into the inspection plan rather than assumed. Most disputes we see are not about a bad casting; they are about a drawing that never said which of the two mattered.
The cell is the same; the acceptance criteria are not. ISO 8062-3 sets the general casting tolerance grades and machining allowances, and the NADCA Product Specification Standards set what die casting can hold on standard features — which is why a telecom heat sink and an EV inverter housing leave the same press with different inspection plans.
Frequently asked questions
What does a typical project start with?
A drawing and an annual volume. From those two we can size the machine, sketch the tooling concept, and give a piece price range within a few days. A firm quotation needs the alloy, the machining content and the inspection requirement, because those three decide most of the cost.
How long does tooling and first article take?
Eight to twelve weeks for most two-cavity tools, plus two to three weeks for T1 corrections. Complex slides, conformal cooling or tight flatness on a thin part extend that. Machining fixtures are built in parallel and are usually ready before the die is.
Do you machine, finish and assemble in house?
Yes. Machining, deburring, impregnation, leak testing, powder coating and sub-assembly with pressed inserts are all done here, which means the leak test happens after machining rather than on a rough casting.
Which alloys do you cast?
ADC12, A380, AlSi10Mg and AlSi9Cu3 cover almost every enquiry. The choice is driven by wall thickness, thermal duty and whether the part will be impregnated, not by the strength figure on a data sheet.
