Appleton, WI: Fox Valley’s Precision Manufacturing Core

The Fox Valley region hosts a dense network of Tier 1 and Tier 2 industrial suppliers with deep roots in precision fabrication for defense, paper machinery, and heavy equipment. Companies like Plexus Corp — a major electronics manufacturing services provider headquartered in Neenah just south of Appleton — reflect the region’s capacity for high-compliance, high-mix manufacturing. Wisconsin’s defense supply chain runs through corridors like this one, and sourcing partners who can meet ITAR and MIL-SPEC standards locally is a persistent operational priority.
