Growth Timeline

1994

MPF Products was formed in 1994 by a group of engineers led by Art Dunton. The company focus was on fabricating unique parts and higher-level assemblies utilizing MPF proprietary ceramic-to-metal sealing technology for the Aerospace Industry.

1999

We opened our new facility with 8,000 square feet. We also launched a standard product line that offered UHV viewports, power feedthroughs, coaxial connectors and thermocouple connectors for numerous industries including Semiconductor, Vacuum Coating, Oil and Gas, Photonics, Nanotechnology, Green Energy and Mil/Aero.

2006

We increased our factory size to 12,000 square feet to accommodate the increasing demand for Electrical Feedthroughs, Viewports and Custom Ceramic-to-Metal assemblies. Additional furnaces, inspection equipment and employees were also added to bring more expertise and technology to MPF.

2010

We upgraded the facility for additional parking, loading dock, security, and increased energy efficiency.

2016

The private ownership changed from Art Dunton to David Dunton. Art retired from day-to-day operations in 2008, but still owned MPF up until 2016. Art sold the company to David, who was previously the General Manager. Duane Mallory was elevated from Sales and Engineering Manager to VP of Operations. John Burnett elevated to Engineering Manager and Kevin Wronoski was hired as Director of Sales and Marketing.

2017

We increased our brazing capacity by over 50% through the additions of High capacity vacuum brazing and wet-atmosphere systems. These systems allow MPF to build much larger assemblies with increased temperature control over large areas. Our welding capacity increased to 6 customized, state-of-the-art, multi-axis, TIG-ARC welding stations.

2019

We have upgraded our design software, inspection equipment, leak test equipment, vacuum brazing capacity, and manufacturing software. MPF continues to invest in equipment and upgrades to our manufacturing tools as our diverse customer base introduces us into new marketplaces with challenging design requirements. We launched a new user-friendly website to help customers navigate over 2,200 standard part numbers and numerous resources. We now have a network of International Partners spanning Europe & Asia, along with highly experienced sales representatives strategically located throughout the United States.
