Quality Control at Every Stage of Production

A comprehensive 5-step process ensures quality from raw materials to final delivery.

Raw Material Inspection (IQC)

No material enters our production floor without verification. We use a spectrometer to confirm the chemical composition and grade of all incoming metals and plastics, ensuring your part starts with the right foundation.

First Article Inspection (FAI)

The first part produced from any new setup is subjected to a full dimensional inspection against the 2D drawing using our CMM and other precision tools. Production only begins after the FAI is approved.

In-Process Quality Control (IPQC)

Our machine operators and dedicated IPQC inspectors conduct regular checks at critical points during the machining process. This allows us to identify and correct any potential deviations in real-time.

Final Quality Assurance (FQA)

Upon completion of a batch, our full-time FQA team performs a comprehensive final inspection. This includes a statistical sampling (or 100% inspection for critical parts) to verify all dimensions, features, and finishes.

Outgoing Quality Control (OQC)

Before packaging, we perform a final check to ensure parts are correctly counted, free of any cosmetic defects, and that all required documentation (material certs, inspection reports) is present.

Verifying Precision with Advanced Metrology

State-of-the-art inspection equipment ensures micron-level accuracy.

Coordinate Measuring Machine (CMM)

The cornerstone of our quality lab. Our high-precision CMMs allow for automated, multi-point inspections on complex geometries to an accuracy of microns, providing detailed and reliable inspection reports.

Spectrometer

Used to conduct Positive Material Identification (PMI), verifying the elemental composition and grade of all incoming raw materials to prevent material mix-ups.

Full Suite of Metrology Tools

Our quality lab is also fully equipped with a Projector, Height Gauge, Micrometers, Calipers, and a comprehensive library of certified thread and pin gauges to conduct thorough manual inspections.

Documentation You Can Rely On

We provide a full suite of documentation to support your quality and regulatory requirements.

Full Dimensional Inspection Reports (from CMM) - Comprehensive measurement data for all critical dimensions.
Material Certifications - Certificates of compliance for all raw materials used in your parts.
Certificates of Conformance (CoC) - Official documentation confirming parts meet all specified requirements.
Support for PPAP (Production Part Approval Process) for automotive clients - Complete documentation package for automotive industry requirements.
