Located on 50-acre campus minutes outside the rapidly growing Greenville, SC, MPF has been supplying feedthroughs and viewports to a myriad of Fortune 500 companies, cutting-edge research laboratories, and emerging tech start-ups for more than 20 years.

MPF is recognized by our customers and suppliers around the world as leading experts in ceramic-to-metal sealing technology. We are dedicated to offering the absolute best products, engineering support, and service.

MPF Products was formed in 1994 by a group of engineers led by Art Dunton. The company focused on fabricating unique parts and higher-level assemblies, utilizing MPF’s proprietary ceramic-to-metal sealing technology.
We opened a 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 Aerospace, Defense, Green Energy, Nanotechnology, Photonics, Oil & Gas, Semiconductor, and Vacuum Coating.


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 added to bring more expertise and improved technology to MPF.
We upgraded our facility to enable continued growth in support of our long-term vision. This included expansions to the business office, loading dock, additional parking, improved security, and energy efficiency improvements.


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.


We 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 processes as our growing customer base continues to increase demand for our products and challenges us with new design requirements. We also launched a new user-friendly website to help customers navigate over 2,200 standard part numbers and the numerous resources we make available.
We now have a network of international partners across Europe & Asia, along with highly experienced sales representatives strategically located throughout the United States.
MPF Products was purchased in 2020 by a group of dedicated long-term investors – Fulham & Co. MPF was immediately provided with larger capital resources to pursue add-on businesses, equipment, and additional personnel.


We have recently received the coveted ISO 9001:2015 certification for quality management systems. For MPF, this designation confirms that the design, testing protocols, and inspection of the thousands of vacuum components we deliver to our partners adheres to the highest quality and performance standards.
