Our Story
The story of Brunk is the quintessential story of the American dream. It started when two Swedish immigrants began an amazing life journey and a remarkable partnership. Ulla Brunk grew up in Spanga Sweden and worked in a bank from a young age. Bertil Brunk came from Ljusdal Sweden and was the son of an auto mechanic. Bertil was fascinated with manufacturing the moment he saw his first milling machine during an apprenticeship at Electrolux.
Crafting Excellence Since 1960
The Swedish immigrants took on America with a work ethic that served them well. Brunk Tool and Die Company started in 1960 in the family’s Lake Geneva garage. As the jobs continued to trickle in, Bertil’s reputation as a tremendous tool and die maker, and designer, began to grow. Bertil’s ability to craft dies that no one else could build drew business from Fortune 500 companies. Honesty, hard work, refusing to accept anything less than excellence, and an attitude of striving for perfection, became the foundation that Bertil and Ulla used to make Brunk what it is today.
Sustaining Quality, Driving Innovation
When Lars Brunk took over the day-to-day operations of the company, he continued to maintain its commitment to quality products, while producing ground-breaking improvements to Brunk’s tools and dies. With his two sons being involved in the business today, the Brunk family’s legacy of superior craftsmanship and dedication to providing a customer-first experience will continue for years to come.
