FATHOM MANUFACTURING LLC

FATHOM MANUFACTURING LLC specializes in the precision fabrication of custom metal and plastic components for specialized government applications, with demonstrated expertise in producing mission-critical assets for transportation infrastructure support. The company leverages advanced manufacturing processes including CNC machining, thermoforming, and sheet metal fabrication to deliver durable, high-tolerance components that meet stringent performance and environmental standards. Their technical capabilities span the full product lifecycle—from design iteration and prototyping to low-volume production and final assembly—ensuring seamless integration into complex operational systems. A key differentiator is their ability to rapidly respond to evolving mission needs with agile, non-standardized manufacturing solutions tailored for federal asset deployment. The contractor has established a consistent working relationship with the Department of Transportation, delivering fabricated metal and plastic components that support national asset systems, likely including signage, structural supports, sensor housings, or control enclosures critical to transportation network operations. Their work suggests deep familiarity with DOT’s logistical and durability requirements for outdoor, high-traffic environments, indicating a pattern of reliable, repeat engagement on mission-essential hardware. FATHOM’s primary industry focus lies in non-standard plastics and fabricated metal products, serving niche segments within transportation and infrastructure sectors. Their NAICS codes reflect a specialization in custom, low-volume manufacturing rather than mass production, positioning them as a responsive supplier for unique, non-commercial-grade components that standard vendors cannot easily replicate. As a small business structured under 2K classification, FATHOM MANUFACTURING LLC operates from its Hartland, Wisconsin facility with no formal government certifications on record. Their geographic presence supports regional federal supply chains while maintaining the agility typical of independent manufacturers serving specialized government markets.
