About Us

Class Tool and Die was founded in 1992 by Jerry Rogosienski with the vision of producing high-quality investment cast tooling. Over the years, our meager beginnings of just two full-time employees turned into a thriving team of eight dedicated to performance excellence. We hope to continue this tradition of growth in the near future.

Between our leading craftsmen, including Jerry's four sons, and trained support staff, we provide 150 years of industry-wide experience, exceptional quality, and unparalleled customer service. We occupy a 10,000-square-foot space in a building big enough for expansion in the thriving center of Mukwonago, Wisconsin.
