    Precision Metal Casting for Prototypes, Pre-Production, and Full-Scale Manufacturing

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.

Materials We Support in Metal Casting

We support a wide range of ferrous and non-ferrous alloys, including high-performance and specialty metals:

  • Aluminum Alloys: A356, A319, 6061, 7075, ADC12

  • Steel Alloys: Carbon steels, alloy steels, stainless steels (304, 316, 17-4)

  • Iron Alloys: Gray iron, ductile iron

  • Copper Alloys: Brass, bronze, beryllium copper

  • Nickel-Based Alloys: Inconel, Monel

  • Titanium Alloys: CP titanium, Ti-6Al-4V

  • Zinc Alloys: Zamak 3, Zamak 5, ZA-8

Our team helps optimize alloy selection for strength, thermal properties, corrosion resistance, and cost efficiency.

Technologies in Our Metal Casting Network

Trustbridge connects you to a global bench of metal casting capabilities:

  • Investment Casting (Lost Wax): Fine-featured parts with excellent surface finish and alloy versatility

  • Sand Casting: Ideal for large parts and complex geometries with low tooling cost

  • Die Casting: High-volume production with tight tolerances and smooth finishes

  • Centrifugal Casting: High-integrity cylindrical parts (e.g., pipes, bushings)

  • Permanent Mold Casting (Gravity Die): Good surface finish and repeatability

  • Shell Mold Casting: Combines detail of investment casting with higher production speed

  • 3D Printed Pattern Casting: Short-run casting with rapid tooling from printed patterns

We pair your needs with the right process based on geometry, quantity, and lead time.

Case Study Highlight

Customer: Industrial Pump Manufacturer
Service: Sand Casting + Machining
Challenge: Needed 100 cast housings with tight dimensional tolerances and 4-week turnaround
Solution: Trustbridge matched them with a U.S.-based sand casting foundry with in-house CNC
Result: Parts delivered in 3.5 weeks, fully machined and pressure tested

“The ability to consolidate casting and machining through a single partner saved us weeks. Trustbridge delivered both speed and accountability.”
Director of Manufacturing, Fluid Systems Company

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.
