Our History
In 1982, Wayne Johnson and Jim Goddyn formed a partnership to produce plastic injection and die cast molds for the manufacturing industry.
They rented a 500 sq. ft. space in Schaumburg, Illinois.
Over the next few years expansion continued and equipment was added, including more Bridgeport Mills, Grinders and EDM Machining Centers.
In 1987 W. J. purchased (2) 50 ton plastic molding press to produce 1st article samples and provide production to customers.
In April 1993, a 1,800 sq. ft. building was purchased in Schaumburg. Expansion continued and equipment was added, including Wire EDM Machining Center and (1) Vertical Insert Molding Machine. As the production increased in the molding area, W. J. purchased (5) more injection molding presses from 50 to 120 tons.
By 1997, W. J. Die Mold had outgrown it’s facilities several times and tripled in size to a new 6,000 sq. ft. building.
A Coordinate Measuring Machine was purchased for new inspection department. W.J. opened a piece part inspection department to handle the increased demand for molded parts to be inspected before tool shipment. And, an increased size in molding led to purchase another 120 ton Van Dorn molding press.
In May 2008, W. J. Die Mold was certified and registered with ISO 9001 with the ISO9001:2000 Quality Assurance Standard. In June of 2010 we updated to ISO2001:2008.
