Family Run and
Driven to Succeed


Unity Precision Manufacturing is a 3rd-generation family-owned company founded as Unity Tool in 1969 by Ron and Irene Van Essen. It all started with a single machine brought into the basement with the young Van Essen boys learning the trade while Irene kept everything in order. Today, Ron and Irene, their son Mike, and grandson Ryan, continue to grow the family business with an entrepreneurial spirit and forward-thinking growth in the medical and commercial/industrial markets.

Unity is a true American success story built from long hours, hard work, and a commitment to quality and customers which still stands strong today.

Why Unity? Because we are proud to focus on unifying elements for the better – better relationships, better turnaround and better quality to ensure our customers’ success. Our name depends on it.

  • Quality and performance come together in each project, delivering success every time.
  • Customers’ ideas and product goals blend with our expertise to ensure manufacturing excellence.
  • Dedicated staff, state-of-the-art equipment, modern facilities and validated processes for proven outcomes.

A commitment to quality brings customers and Unity together, creating highly valued relationships based on trust and honesty.

We are proud to have grown Unity into a precision-driven, customer-focused, global contract manufacturing company. We are dedicated to helping customers to reach the pinnacle of manufacturing excellence – and we go miles beyond simple machining to deliver outstanding service and partnership.
