& Operated

Pride & Precision from Deep in the Heart of Texas

Turnco was established in 1981 by Granville “Doc” Turner and his daughter, Sandra Griffin. Originally established to service the demanding needs of the high-tech and semiconductor industries, we have continued to grow our business and expand into the medical, aerospace, nuclear, and defense sectors. Today, with the third generation of family now involved in the daily operations, we continue our legacy of quality contract manufacturing.

In 2018, Turnco completed construction of a new 20,000 square foot facility designed to maximize efficiency through machine layout and product flow. Planning for the addition of new capabilities was taken into consideration when designing the facility, as we continue to focus on our future and our customers’ needs.

Because of our continuing commitment to the highest quality processes, Turnco maintains both ISO 13485:2016 and ISO 9001:2015 certification. Our policy to exceed expectations (E²) is achieved through quality, on-time delivery and customer satisfaction.

Our goal is to provide every Turnco customer with the highest quality machined parts at the lowest prices possible. We accomplish this goal every day by continually improving our processes and creating an environment that encourages teamwork, training, and development.
