Die Casting Parts — Aluminium & Zinc, High-Volume Production
Die casting is the highest-throughput casting process, built for large runs of thin-walled aluminium and zinc parts. If your volume is high and your wall sections are thin, die casting delivers repeatable parts at the lowest piece cost.
What Die Casting Delivers
Molten metal is injected into a steel die under high pressure, giving thin walls, tight repeatable tolerance and fast cycle times. The trade-off is a higher tooling cost — which pays back fast at production volumes.
| Parameter | Typical capability |
|---|---|
| Materials | Aluminium alloys (ADC12/A380), zinc alloys (Zamak 3/5) |
| Part weight | 10 g – 15 kg |
| Wall thickness | Down to 0.8 – 1.2 mm |
| Dimensional tolerance | CT4 – CT6, high repeatability |
| Tooling | Steel die, higher cost — amortised over the run |
| Typical volume | Thousands to millions of parts per year |
Materials & Finishes
| Material | Common grades | Typical finish |
|---|---|---|
| Aluminium | ADC12, A380, AlSi9Cu3 | Machining, anodising, powder coating |
| Zinc | Zamak 3, Zamak 5 | Machining, plating (chrome, nickel) |
Where Die Casting Fits
Die casting suits housings, enclosures, brackets and structural parts where volume justifies the die. For low-volume or heavy parts, sand or investment casting is usually the better fit — we will tell you honestly which process to use.

FAQ
How much does a die casting die cost?
It depends on part size, cavity count and complexity. We quote the die and the piece price separately so you can see the break-even volume before committing.
What volume do I need for die casting to make sense?
Generally thousands of parts per year. Below that, sand or investment casting is usually more economical — we recommend the process that costs you less in total.
Can you do secondary machining and finishing?
Yes — machining, tapping, anodising, powder coating and plating are all available in-house or through vetted partners.
