Overview

Die casting injects molten metal under high pressure into a steel mold (die), producing near-net-shape parts with excellent dimensional accuracy and surface finish. Our hot-chamber and cold-chamber die casting machines handle aluminum, zinc, and magnesium alloys.

Ideal for complex geometries with thin walls — from consumer electronics housings to automotive components. Production volumes from 1,000 to 500,000+ parts per year.

Frequently Asked Questions

What die casting processes do you offer?

We offer both hot-chamber die casting (for zinc and magnesium alloys with lower melting points) and cold-chamber die casting (for aluminum alloys). Our machines range up to 500 tons clamping force.

What is the minimum wall thickness for die casting?

For zinc alloys, we can achieve wall thicknesses as thin as 0.8 mm. For aluminum alloys, the minimum is typically 1.5 mm. Magnesium falls between these ranges at approximately 1.0 mm.

How long does die casting tooling take?

Mold design and fabrication typically takes 3–6 weeks depending on part complexity, number of cavities, and surface finish requirements. Rush tooling options are available.

What surface finishes are available for die-cast parts?

We offer powder coating, e-coating, chrome plating, anodizing (aluminum), electroless nickel plating, and liquid painting with custom color matching. As-cast surface finish is typically Ra 1.6 μm.

What is the typical production volume for die casting?

Die casting is ideal for production volumes from 1,000 to 500,000+ parts per year. The steel mold tooling investment is amortized over the production run, making it most cost-effective at higher volumes.

Can die-cast parts be machined after casting?

Yes. We offer secondary CNC machining, drilling, tapping, and boring operations for die-cast parts that require precision features, tight-tolerance bores, or threaded holes beyond what the casting process can achieve.

Do you offer mold design and fabrication in-house?

Yes. Our in-house mold design team uses mold flow simulation to optimize gate placement, runner design, and thermal management before cutting steel. This reduces trial runs and improves first-article quality.
