MPF Products

What MPF Products does

MPF Products, Inc. is a vertically integrated US manufacturer specializing in ceramic-to-metal hermetic assemblies for ultra-high vacuum (UHV) and extreme-environment applications. Founded in 1994 in Gray Court, South Carolina, the company operates from a 19,000+ square foot facility and produces electrical feedthroughs (power, RF, thermocouple, fiber optic, coaxial, multipin, and crystal sensor types), UHV viewports (including sapphire, fused silica, and YAG crystal), UHV isolators, baseplate and beam-positioning feedthroughs, and related accessories. Core technology centers on proprietary ceramic-to-metal sealing processes that bond alumina ceramic to Kovar, stainless steel, or other metals, supported by in-house vacuum brazing, multi-axis TIG welding, XRF material analysis, and helium leak testing to 1x10^-9 cc/sec He. MPF holds ISO 9001:2015 certification (2021) and distributes through a network spanning more than 20 countries alongside direct US sales and an e-commerce storefront.

The company serves Fortune 500 OEMs, national research laboratories, and technology startups across semiconductor capital equipment (PVD, ALD, CVD, ion implantation, EUV lithography), aerospace and defense (radiation-tolerant and directed-energy systems), medical imaging (CT, PET, X-ray, proton therapy, cryo-EM), photonics and laser systems, fusion and advanced energy research, and quantum computing. Revenue is generated through three streams: sale of 2,200+ standard catalog components (hardware), custom engineering and manufacturing services for application-specific assemblies (project-based, multi-year contracts), and — since the 2022 acquisition of Blue Ridge Optics — precision optics and thin-film coatings for high-energy laser systems. Go-to-market is sales-led through dedicated account executives, supplemented by authorized international distributors and an e-commerce channel for long-tail SMB and individual researcher purchases.

Since 2020, MPF has operated as a portfolio company of private equity firm Fulham & Co. Ownership transitioned from founder Art Dunton to David Dunton in 2016, and key executives include Duane Mallory (VP of Operations), Kevin Wronoski (VP of Sales and Marketing), and John Burnett (Engineering Manager). Subsequent moves include the 2022 Blue Ridge Optics acquisition, a 2024 facility expansion adding R&D and clean-room capacity, the 2025 launch of YAG UHV viewports, and an October 2025 second clean-room addition — collectively indicating a deliberate buildout of capabilities targeting next-generation semiconductor, quantum, and directed-energy applications.
