Quality Program

Our commitment to quality is exemplified by our early transition to ISO 9001:2000, and a schedule of external audits occurring every 6 months.  In addition, we have been audited and approved by NASA Marshall Space Flight Center for flight with no restrictions (Supplier # 80), which has led to a number of approvals by prime contractors and inclusion in a Ship-to-Stock program.  Our Calibration complies with the ANSI /NSL Z540-1 standard.  Inspections are performed with tolerances ranging to .0001".

We have developed a slide show that displays some of the variety of parts, projects and assemblies we have made.
