CHICOPEE, MA, May 2018—Duval Precision Grinding has passed its yearly recertification audits with good merit. The audits verified their compliance to the new AS9100 (Rev D) standard and renewed the company’s NADCAP accreditation.

“Considering the scope of the changes made to both the AS9100 and NADCAP requirements, , we were very pleased to see positive results with no more than a handful of minor corrections,” said Duval Precision Grinding president, Ron Parlengas. “The entire Duval team went above and beyond to demonstrate their knowledge of the new requirements.”

“Achieving NADCAP accreditation is not easy: it is one of the ways in which the aerospace industry identifies those who excel at special processes. Companies such as Duval Precision Grinding work hard to obtain this status and they should be justifiably proud of it, “ said Joe Pinto, Executive Vice President and Chief Operating Officer at the Performance Review Institute.

The auditor interviewed employees and reviewed documentation at all levels. Policies, procedures, and systems operations were reviewed with process owners to validate compliance.

In March 2018, Duval renewed its AS9100 / ISO 9001:2015 certification to the Revision D level which requires the company to assess risks and opportunities throughout all its processes with a focus on continuous improvement.   

In October 2017, Duval renewed its NADCAP accreditation by demonstrating ongoing commitment to quality by satisfying customer requirements. The company passed with good merit and an extension of their audit period from every twelve months to every eighteen months.
