Joseph Johnson and his wife Mary founded Jomar in 1968, giving it its name. Joe oversaw the injection blow molding division at Wheaton Industries as a design engineer. After leaving Wheaton, Joe developed the device and founded a new business. He established a business that produced the first fully integrated, commercially successful injection blow molding machinery for the plastics industry.

Inductotherm Industries of Rancocas, New Jersey, a privately held business that has produced more than 50 percent of the world's induction furnaces, acquired Jomar in 1978.

We currently have a 42,000 square foot headquarters in Southern New Jersey, and we have sold over 2,000 machines globally.
