Our approach to quality combines the most challenging requirements of each customer and every OEM engine builder into one cohesive internationalized system.

The United Precision Products team maintains control and oversight of all manufacturing processes by requiring first-piece inspections at every manufacturing step, ensuring quality at the source.

We maintain extensive, independent third party over-checking of products, which are conducted by approved testing laboratories. We utilize only approved sources for all outside steps in the manufacturing process and provide Statistical Process Control for all critical processes as required.

We are committed to continuous improvement and waste elimination for all steps in our manufacturing processes, helping not only the environment, but also your bottom line. For over 15 years our team at UPP has maintained strict adherence to the international standards for AS9100 and ISO9001. With a high rate of retention among our highly skilled and dedicated workforce, we have been able to successfully complete the Defense Contract Management Agency’s Annual Surveillance Audit and Statement of Qualification for QSLM and Government’s ISO certification program.

We continually work within the requirements of numerous OEM quality programs including: SPOC (Honeywell), LCS/MCL (Pratt & Whitney), SABRe (Rolls Royce) S500/S100 (General Electric) and more.

Quality at the Source

Cost effectiveness, delivery performance, and value-added all stem from our dedication to quality. Our Quality Assurance Management report directly to the President. This top-down commitment to quality provides the continuous focus needed to maintain our ISO9001 and AS9100 registrations.

We have developed a quality plan that is the result of a documented series of review, processing, manufacturing, and inspection steps that together produce, document, and maintain the required level of quality in  all manufactured components, all of which have qualified us for ISO9001 with AS9100 certification, QSLM listing status, and ISO certification with the US government.
