What Strohwig Industries does

Strohwig Industries, Inc. is a privately held U.S. contract manufacturer founded in 1978 and headquartered at 3285 Industrial Road, Richfield, Wisconsin. The company operates two divisions — a Machining Division (CNC/5-axis machining, boring, EDM, welding, polishing) and a Tooling Division (injection moulds, die cast dies, custom forging dies) — and serves enterprise customers in defense, aerospace, energy, and industrial programs that require large-scale, high-tolerance components produced under controlled processes and documented workflows. Its facility runs around the clock with 20-ton crane capacity, and is supported by a full-time two-shift maintenance department and an ISO 9001:2015 certified quality control division.

The business is qualified for highly regulated end-markets, holding AS9100D (aerospace quality management), ISO 9001:2015, and CMMC Level 2 (DoD cybersecurity) certifications, the last of which was completed in April 2026. Strohwig monetizes exclusively through custom, quote-based contract manufacturing services sold via direct field sales and a request-for-quote workflow on its website; no public pricing, channels, or distribution partners are disclosed. There is no public revenue, no disclosed funding, no parent company, and no named customer roster in the available data, leaving the financial scale of the business inferable only via the 101–250 employee headcount range. The company presents itself as a mission-critical, craftsmanship-led supplier — emphasizing over 800 years of combined machine operator experience, preventative maintenance programs, and engineering-to-production capabilities including prototyping and reverse engineering.
