Quality Assurance

and Manufacturing Excellence

Sterling Spring has established a rigorous formula for quality control for all of our spring manufacturing projects. By incorporating a computerized tracking system, on floor status reporting and maintaining an in-depth inventory, Sterling Spring is able to inform customers where their spring product is at any given moment in the factory. Whether we’re producing extension springs, spiral torsions, clutch springs or light metal stampings, none of our manufactured spring products leaves the plant until approved by quality control.

Sterling Spring is very proud to have earned TS16949 certification and ISO9000 certification. Achieving these certifications is a testament to the focus our team has on quality and excellence. It is also a testament to our never-ending pursuit of top-notch customer service. A better quality product strengthens our relationship with you, our customer.

Manufacturing quality spring parts for the 21st century takes more than quality employees. The close tolerances and consistent quality our products possess couldn't happen without our focused investment in modern spring production equipment. Sterling Spring implements over 100 pieces of modern production equipment including winders, grinders, processing ovens, four slides, punch presses, continuous coilers, hand coilers and kick presses.

Modern equipment and an expert staff work in concert at Sterling Spring to produce high quality and cost effective parts for any manufactured spring need. The run size is no concern to us. We, at Sterling Spring, know we can give you the product you asked for. Our concern is to give you the best customer service possible while turning out an incredible product. Quality control takes care of the product and your account manager personally takes care of your concerns.
