Prototype castings that accelerate design and production

Bridge the gap between concept and production with fast, accurate prototype castings. Our short-run process helps you test fit and function early, refine designs quickly, and move to production with confidence.

Prototype casting services

We help you test real parts, fix problems early, and move to production with confidence.

Rapid prototype casting

Short-run castings that bridge the gap between concept and production.

Fit, form, and function testing

Validate real-world performance with accurate prototype castings.

Design iteration support

Refine designs quickly between cycles with our engineers by your side.

Flexible volumes

Produce a handful of parts — or a few dozen — with minimal setup.

Reduce risk and lead times with prototype castings

Physical prototypes give you certainty before scaling. By testing real parts in real conditions, you reduce surprises, avoid rework, and keep projects on budget and on schedule.

  • Prevent costly tooling changes and design revisions
  • Verify material performance in actual operating conditions
  • Catch issues early before they cascade downstream
  • Accelerate time-to-market with validated designs
