Quality Control & Metrology

Our automotive quality system operates under IATF-compliant protocols and advanced metrology. We execute full-spectrum verification, from material certification to CMM inspection, to validate every prototype against your engineering and safety specifications.

Learn More
  • In-Process Inspection

    Real-time dimensional monitoring and first-article validation during machining to prevent cumulative tolerance errors.

  • Dimensional Verification

    CMM inspection and 3D scanning to verify complex automotive geometries against original CAD data.

  • Traceability Records

    Full digital tracking of production batches, machine logs, and operator data for complete supply chain transparency.

  • Quality Documentation

    Standardized reporting packages including FAI reports, Material Test Reports (MTR), and PPAP Level 3 documentation.

Production

Scalable Low-Volume Production

We bridge the gap between initial prototyping and mass production by scaling our facility for low-volume automotive runs. We implement strict process controls and DFM transitions to ensure absolute component consistency and functional performance across every production batch, reducing your transition risks.

What Our Clients Say?

  • 72 M +
  • 2,300 +
  • "Honestly, you guys saved my skin. I sent over a small batch of 7075 aluminum housings with some pretty crazy tolerances, and you actually delivered. Shipping costs to the states are a bit high, but the quality is much better than the local shops I've used."

    Derek V.

    - Mechanical Engineer

  • "Top marks for the rapid prototyping speed. You turned around those billet water pump covers in just 4 days. Had a small issue with one thread, but you fixed it fast. It is hard to find a shop that actually listens to engineering feedback these days."

    Olivia M.

    - Automotive Designer

  • "I was worried about the complex geometry on our suspension brackets, but you handled the 5-axis milling perfectly. bits of oil still on the parts when they arrived, but who cares? the dimensions are spot on. will send more files soon."
