We Help Technical Teams Bring their Design to Life when Traditional Machining Can’t…
Bullen is a family owned and operated company located in Eaton, Ohio. Founded in 1971, we’ve continuously refined our approach to effective ultrasonic machining while prioritizing culture, customers, and community.
What started as a small group of engineers repairing ultrasonic equipment in their garage has turned into a “machining powerhouse” and globally recognized industry leader. Despite our growth, we remain just as committed to our employees and our customers, and our community as we were on Day One.
