Quality Engineering Services was founded in Wallingford, CT in 1971 by owner and president, Richard Addy. The original business focused on die work and precision machined parts. We have since grown from two to over forty five employees located in a modern climate controlled facility in Wallingford at 122 North Plains Industrial Rd.

We continue to invest heavily in the latest CAD software and computers, CNC and manual machines, inspection equipment, and employees. This allows us to maintain a high level of quality and meet our customers’ needs for tooling in a cost-effective and timely manner.
