Metal Casting Services

Trustbridge offers full-spectrum metal casting services through a global network of certified foundries and casting specialists. Whether you need functional prototypes, short-run pre-production parts, or full-scale metal component manufacturing, our platform connects your requirements to suppliers with the right alloy, casting method, and finishing capabilities.

From investment casting to sand and die casting, we support diverse industries with high-strength, complex geometries — all backed by engineering support, global sourcing flexibility, and a single point of contact for quality assurance.

What Tolerances Can You Expect?

Tolerances depend on casting method, alloy, and part geometry, but our partners consistently achieve:

Investment Casting: ±0.005 in/in (±0.127 mm per inch), as tight as ±0.003 in for small features
Sand Casting: ±0.010–0.020 in/in (±0.25–0.50 mm per inch), depending on mold type
Die Casting: ±0.002–0.005 in (±0.05–0.13 mm), high repeatability
Surface Finishes: As-cast to 63 Ra or better with machining or polishing
Post-Cast Machining: Available for tighter tolerances or critical surfaces

Trustbridge engineers can help plan for shrinkage, draft angles, and post-cast tolerancing as needed.

Frequently Asked Questions

What’s the difference between investment, sand, and die casting?

Investment Casting: Best for detailed parts, lower volumes

Sand Casting: Lower tooling cost, flexible geometry

Die Casting: Best for high-volume runs, especially aluminum and zinc

What post-processing services do you offer?

We offer machining, heat treatment, polishing, anodizing, painting, powder coating, and NDT testing.

Can I use 3D-printed patterns for short-run casting?

Yes — many of our partners support rapid pattern generation using SLA, FDM, or binder jet printing.

Do you support cast + machined parts in one job?

Yes — we can bundle casting and post-processing into a single quote and project workflow.

Can I get help choosing the right casting process or alloy?

Absolutely. Our engineering team provides hands-on guidance at every stage.
