Upstate Companies Broaden Operational Excellence Exposure

Group photoManufacturing companies in South Carolina continue to expand their operational excellence exposure. In February, two more companies joined the growing OpExChange bench marking network. Stoll Industries and Kelley Engineering – both from the Upstate region of the state– joined forces with the preeminent manufacturing collaboration group in the state.

“We are delighted that these two chose to join in 2021,” said Mike Demos, the South Carolina OpExChange Coordinator. “Our member companies have a lot of improvements to share in lean manufacturing, advanced manufacturing, and leadership.”


Located in Abbeville, South Carolina, Stoll Industries is a third-generation, family-led business founded by Bill Stoll. They specialize in custom metal products for all rooms of the house. They have expanded to include not only residential products but also custom creations for the commercial and business world. Darris Stoll, Operations Manager for Stoll, said “I guess we got it from Grandpa, we love to create new things, … to figure out a way to do things that maybe someone else has not had success in doing.”



Kelley Engineering is a premier engineering and manufacturing company serving a broad customer base across the southeast. This fast-growing company in Piedmont, South Carolina specializes in designing and building custom automation equipment as well as providing CNC machining and metal fabrication services to a variety of industries including aerospace, automotive, ceramics, injection molding, medical, packaging, tires, and general manufacturing. The Kelly Engineering motto is, “There is a better way. Let’s find it!”


The OpExChange is a peer-to-peer network of companies in South Carolina dedicated to learning and growing together. Member companies host events and share practical examples of industrial automation, lean manufacturing improvements, and leadership development. It is an invaluable resource to South Carolina companies that provide access to others who are on similar improvement journeys.
