Our History
Diemasters was founded as a high precision tool builder on Chicago’s West Side in 1948. From these roots more than 70 years ago, our business has been committed to quality craftsmanship while we have evolved to new capabilities, market reach, and customer expectations. Today, our customer base spans across more than 50 countries worldwide. Each day, 120 certified employees at our 80,000 sq. ft. production facility turn out more than 250,000 stamped parts, assemblies, and fabrications. And even though we’ve grown exponentially, Diemasters remains committed to providing a personal touch, along with our high-quality precision products.
Diemasters was fully acquired by Weiss-Aug Group in 2020, allowing us to collaborate on technology, product development, and customer outreach.
