ISO-Certified Quality Assurance for Precision Manufacturing

At Vanderhulst Associates Inc., quality control and precision inspection are at the core of everything we do. With ISO 9001:2015 & AS9100 certifications, we ensure that every CNC-machined component, assembly, and prototype meets stringent industry standards.

Our San Jose machine shop is equipped with advanced metrology tools, CMM inspection, and functional testing capabilities, guaranteeing that every part is measured, tested, and verified before delivery.

Advanced Metrology & Precision Inspection Services

We use state-of-the-art inspection equipment to ensure tight tolerances, dimensional accuracy, and superior part quality.

  • CMM (Coordinate Measuring Machines) Inspection – Ensures precise, repeatable measurements with sub-micron accuracy.

  • Optical & Vision System Inspection – Detects microscopic deviations in precision-machined parts.

  • Surface Finish Analysis – Verifies smoothness, coatings, and material integrity for medical and aerospace components.

  • Full First Article Inspection (FAI) – Ensures every part meets customer specifications before production scaling.
