A successful career in the plastics industry can start in some unusual places and be fueled by unexpected opportunities. Jeff Kuhman started in professional football and Maureen Steinwall started as a certified public accountant. 

The five successful plastics industry entrepreneurs profiled below felt the lure of manufacturing and took different paths to success, but they all have useful lessons to teach today’s industry leaders.    

Steinwall: Kind, caring leader who is inquisitive about life 

Maureen Steinwall worked as a certified public accountant for six years before the lure of manufacturing pulled her first to Honeywell Micro Switch and then to purchase her father’s mold making and injection molding business. She took over in 1987, became active in the Plastics Industry Association (PLASTICS) and has earned a solid reputation as one of the industry’s most respected leaders.

Along the way, Steinwall also earned two master’s degrees and a Ph.D. in business. She has built Steinwall Inc. into a successful company on the ideals of motivating and encouraging employees to better themselves. Now she is looking ahead to new challenges.

Jackson: Blow molding machinery has been his life’s passion 

Bob Jackson started his career selling all types of plastics processing machinery to the automotive industry. But his next job with Davis-Standard Sterling focused on blow molding machinery and gave him a direction for a long and successful career.   

Jackson has sold blow molding machinery as a distributor, founded his own company and eventually started building his own machines. He also does a big business in rebuilding blow molding machines. His customer-centric business practices have made Jackson Machinery Inc. a go-to source for blow molding machinery.

Petrakis: Leaving his mark on the people of the plastics industry 

Steve Petrakis did it all — sold machinery, sold robotics, ran his own manufacturing company, was president of a company that brought new cooling technology to the United States and directed sales and marketing for auxiliary equipment supplier Conair. But it was during two tours with the Plastics Industry Association (PLASTICS) that he left his longest-lasting mark.

Petrakis proved a master at meeting and giving talks to up-and-coming plastics professionals, helping them find their way as they charted their own paths. The now-retired VP of industry affairs, equipment and mold makers council for PLASTICS touched the lives of many professionals now in the upper echelons of management.

Kuhman: Plastics lured him away from pro football 

Jeff Kuhman played pro football after college and took an off-season job with Hartig, a manufacturer of extruders and blow molding machines. “I really enjoyed what I was doing, so I decided not to return to camp and to pursue a career in plastics,” he said, explaining why he decided to end his football career after two seasons.

Ten years later, he saw an opportunity for feed screws and barrels and formed Great Lakes Feedscrews. That business expanded and he eventually changed the name to Glycon Corp. Now it provides a full range of engineered components, along with design capabilities and field services to OEMs and processors worldwide.

Witherup: Successful plastics industry career followed by politics 

Conair hired Vince Witherup for a consulting project to decide if it should start selling complete material handling systems. He recommended Conair should do it and added that he should be hired to head up the new business segment. That launched a 40-year career at Conair, with Witherup working his way up to VP of international sales and marketing.

Witherup retired from Conair in 2007 and two years later became a county commissioner in Venango County, Pa. Did the plastics industry prepare Witherup for politics? Read the full interview.
