What Welch Fluorocarbon does
Welch Fluorocarbon, Inc. is a Dover, New Hampshire-based custom manufacturer founded in 1985 by Evan Welch and currently operating as a subsidiary of UFP Technologies, Inc. The company specializes in thermoforming and heat-sealing thin high-performance fluoropolymer films — including PTFE, FEP, PFA, Modified PTFE, PEEK, Ultem PEI, and Aurum TPI — into intricate custom three-dimensional shapes. Its core technical capability is producing ultra-thin walled components (down to .001") with tight tolerances (+/- .002" for thermoforming, +/- .005" for trimming), enabled by proprietary high-temperature thermoformers and heat sealers designed and built in-house. PLC-controlled automation with vision inspection supports consistent production quality. Welch Fluorocarbon converted to ISO 13485:2016 in 2018 and operates a 30,000 sq ft manufacturing facility with clean room assembly, serving medical devices as its primary vertical alongside aerospace (including NASA), biotechnology (cryogenic storage integrated with BioArchive systems), battery technology, electrical components, environmental science, and cannabis.
