When Alfred Fain founded a small Rhode Island tire store in 1924, at the time no one could have predicted how Teknor Apex would become an international custom compounder sought out by companies around the world. After a nearly hundred-year journey that’s carried us through acquisitions and expansion, we now have nine U.S. locations, as well as operations in Belgium, Singapore, Germany, and China.

After a nearly hundred-year journey that’s carried us through acquisitions and expansion, we now have nine U.S. locations, as well as operations in Belgium, Singapore, Germany, and China.

Throughout this global expansion Teknor has remained a privately held company, and today Fain’s grandson sits at the helm, maintaining the family’s tradition of fostering deep employee and customer relationships. These relationships are what allow us—together—to deliver customized compound solutions and help our customer’s create better products.

“Manufacturing is a team sport, and we work together to achieve our goals.” ~Jon Fain
