Edwardsburg-based Duo-Form Named Michigan Manufacturer of the Year for 2022, wins the Michigan Manufacturers Association (MMA) Manufacturing (MFG) Excellence Award-Large Tier

Edwardsburg, MI- November 11, 2022 Duo-Form has been honored with statewide recognition with the 2022 MFG Excellence Award, presented by the Michigan Manufacturers Association (MMA).


The MMA honored the winners of the 2022 MFG Excellence Awards during a celebration last night on Thursday, Nov. 10, 2022, in Lansing. The MFG Excellence Awards is the annual statewide celebration of the exceptional contributions that Michigan manufacturers make to their workforce, their communities, the economy and the industry. The program promotes the inspiring stories of Michigan’s manufacturing industry, the thousands of unique manufacturing companies across the state, the hundreds of thousands of Michiganders employed in the industry and the local communities that support it.

Duo-Form, an ISO 9001:2015 certified heavy gauge plastic thermoformer, is an industry leader in the RV OEM industry, and provides a variety of thermoformed products to the RV industry, used by internationally recognized businesses including a complete line of skylights, bath and RV lifestyle products. Last year, Duo expanded their RV parts offering to the ever-growing RV aftermarket- and has launched over a dozen products designed and developed especially for existing RV owners wanting to repair and rehab or update and modernize their existing RV.

“We would not have won this award without the help of our entire DUO team, from production floor to mid-level and senior management,” explains Shelly Ditmer, Duo-Form President. “We have reinvented the way we think about employee culture and engagement. Our focus on the DUO culture has resulted in increased productivity and effectiveness through the creation of a Culture Task Force and a DUO Safety Team.”

Mike Gonser, Duo-Form VP of Operations, further explains this sentiment, “When COVID hit, we would not have turned around a superior face shield in 48 hours without a strong teamwork mentality,” Mike says. “We have a strong team at DUO and I’m so proud to bring this award back for all of our employees. Our staff has remained flexible and reactive from the beginning of Covid, until now, as we continue to innovate, grow, and develop new products and product lines. This award solidifies to us that we are on the right path and reinforces our desire to continue to grow through automation, innovation, and simple ingenuity.”

“It’s a major honor, to receive the 2022 Manufacturing Excellence Award” Ms. Ditmer continues, and we are proud to represent Southwestern Lower Michigan and celebrates this recognition to Michigan’s workforce, communities, and economy. At the same time, we would like to congratulate all of our fellow nominees and winners, we are truly humbled to be honored with other amazing companies, all of who were equally deserving.”
