Die casting · by quote

High-pressure die casting

For volumes where machining stops making sense. Send your STEP and target annual volume, we'll quote the die, the casting and the machining together, with a DFM review of draft, wall thickness, porosity risk and gating first.

Discuss your requirements
Illustrative die-cast metal housings with machined features
Alloys

ADC12, A380, AlSi9Cu3, ZA-8 zinc, AZ91D magnesium

Part size

10 g to 8 kg shot weight, up to 800 tonne machines

Tooling

H13 steel dies, single or multi-cavity, 5–7 weeks

Wall & draft

1.5–4 mm nominal wall, 1–2° draft, generous radii

Secondary work

Trim, shot blast, CNC machining, tapping, leak test

Finishing

As-cast, powder coat, anodise (Al), chrome or e-coat

Choosing a material

Casting alloy affects weight, wall thickness, corrosion resistance and the secondary machining needed for critical features. Final grade and tooling are agreed after a manufacturability review.

Aluminium
Light and strong with good thermal performance. Often suited to housings and heat-sink geometries.
Zinc
Flows into thin walls and fine details. Consider for smaller, intricate components.
Magnesium
Very low weight at the cost of more specialised handling. Useful where mass is critical.

What the tooling review covers

01

Wall, draft and parting

Consistent walls and draft help the casting leave the die. Undercuts and complex parting lines may require extra tooling work.

02

Porosity and critical faces

Point out sealing surfaces, threads and pressure-bearing areas. These may need machining, testing or a change in gate location.

03

Volume and finishing

Share the expected annual volume, alloy and coating requirements so tooling and per-part costs can be reviewed together.

Related processes

Choose by production volume, material, geometry, and tooling commitment.

CNC machining

Better for prototypes, low volumes, tighter tolerances, or parts that do not justify dedicated tooling.

View service

Injection moulding

Better for high-volume plastic parts where low weight, insulation, or complex polymer features matter.

View service

Aluminium extrusion

Better for long parts with a constant cross-section, then cut and machined to final length.
