Our History

The company began with Erich Dickten and Alfred Masch who immigrated to the United States from Germany in the mid 1920’s, started a tool shop in Milwaukee in 1941, and began building dies for Cutler Hammer. In 1942 they started molding thermoset periscope components for Army tanks and in 1946 built a 12,000 square foot facility at 900 East Vienna Avenue. The building was expanded in 1955 and again in 1960 to the current 38,000 square feet.

Duane Kreske, a tool maker by education, started working at Dickten & Masch in 1961 as an engineer, later became the quality manager, then plant manager, and purchased the business in 1987, at which time the company became known as Wisconsin Thermoset Molding or WTM.

Boyd Miller, who graduated from General Motors Institute as an electro mechanical engineer, and with previous work experience at Delco Electronics, Milwaukee Electronics, US Controls, Ark-Les, Invensys Appliance Controls, and Stroh Die Casting purchased the business in 2008.

Today,  Cornerstone Composites, Inc. continues to provide outstanding customer service and high quality thermoset products to various industries. Our commitment is to be your best supply chain partner in providing highly engineered products to enhance your market share.
