What Waukesha Metal Products makes

Waukesha Metal Products is a contract metal stamping and sheet metal fabrication manufacturer founded in 1971 in Sussex, Wisconsin. The company runs progressive die, transfer die, and stage-die stamping, and it builds its own tooling in-house rather than buying dies from outside shops. Its stamping floor spans more than 20 presses from 1.5 to 660 tons, with bed sizes up to 145 inches and speeds up to 400 strokes per minute. Coil-fed lines handle material from 0.008 to 0.375 inches thick and up to 50 inches wide.

The work is not limited to presses. A full fabrication side runs CNC turret punching, high-wattage laser cutting, and brake forming up to 176 tons, feeding robotic and manual welding cells and final assembly. The company describes a proprietary die-sensor program that adds in-die measurement, in-die welding, and in-die assembly, which lets it validate parts during the stroke rather than after. Value-added services include plating, anodizing, powder coating, and machining, so a part can move from raw coil to finished assembly under one roof. Materials span low-carbon and high-strength low-alloy (HSLA) steel, stainless, cold-rolled and galvanized steel, spring steel, tin-plated steel, copper, bronze, aluminum, and brass.

Customers are automotive OEMs and tier suppliers first, followed by aerospace, defense, energy and storage, medical, HVAC, industrial equipment, consumer products, and security. The company supports programs from short-run prototypes through high-volume production and states it serves customers across the US, Mexico, Latin America, Germany, and Japan.

Equipment and facilities

Waukesha Metal Products operates three plants totaling roughly 200,750 square feet, each with a distinct role. The Sussex, Wisconsin headquarters (48,750 sq ft) is the stamping and tool and die center, home to a 660-ton SEYI press, a Komatsu 330-ton servo press for programmable motion, a Minster 600-ton press, and the in-house tool room with wire EDM, CNC mills and lathes, grinders, and a heat-treat furnace. The Grafton, Wisconsin plant (42,000 sq ft) handles high-mix, low-volume sheet metal fabrication and welding, equipped with a Mitsubishi 4,000-watt fiber laser, an Amada VIPROS 358 King II CNC turret punch, and CNC brake presses. The San Luis Potosi, Mexico plant (110,000 sq ft) is the high-volume site, adding tube fabrication, robotic welding, and stamping up to 600 tons in the center of Mexico's manufacturing corridor.

The quality lab backs this with two Zeiss Contura CMMs with VAST scanning, Brown and Sharpe 9159 CMMs running PC-DMIS, and FabriVISION optical inspection. The company reports seven-day production capability and runs its floor on automation, ERP tracking, and cellular manufacturing.

Ownership and history

Waukesha Metal Products has operated since 1971 and is a privately held, independent Wisconsin manufacturer with no parent company or private-equity owner on record. It grew from a single Southeastern Wisconsin stamping operation into a three-plant group spanning Wisconsin and Mexico, with more than 170 team members.

Jeffrey Clark has led the company as president and CEO, and in a 2025 interview he was also described as a partner at Sussex Machine Company, a precision machining firm in Waterloo, Wisconsin. In April 2026 the company named Jeff Mason as Chief Operating Officer; Mason previously served as COO of the Edelbrock Group and held operations leadership roles at Nemak, Kennametal, and Cooper Standard. The company emphasizes long tenure on its floor, stating that many team members have been with the business for more than a decade.

Certifications and quality

Waukesha Metal Products maintains ISO 9001:2015 quality certification and IATF 16949:2016 automotive certification across all three facilities, plus ISO 14001:2015 environmental certification, all issued by NSF-ISR. Its Grafton facility is ITAR registered with the U.S. Department of State's Directorate of Defense Trade Controls (registration M34405), which supports defense manufacturing work. The company states it maintains AS9100 compliance for aerospace readiness, which it presents as compliance rather than full certification, and says it is in the final stages of achieving CMMC certification for secure defense programs. Its quality engineers provide PPAP and APQP documentation, FMEA submissions, Gage R&R studies, statistical process control, and capability studies as standard for regulated programs.

Known customers

Waukesha Metal Products does not publish a named customer list, which is normal for a contract stamper serving OEM programs under confidentiality. The public record supports the sector rather than specific accounts:

Beyond these, the company names aerospace, energy and storage, medical, HVAC, and security among its served industries, but individual customer names are not published and are not asserted here.

Sourcing evidence

Waukesha Metal Products has a small and dated US import footprint. Public bill-of-lading records show a Grafton entity with 21 US sea shipments, the most recent in October 2022. That thin record is consistent with the company's stated sourcing model: in 2025 the CEO said the company sources most of its metal domestically and imports only a few components, such as certain bolts and magnets, that are no longer made in the United States. The company's Mexico plant is positioned for nearshore, tariff-conscious supply for its North American programs rather than for importing finished goods into the US, a distinction relevant to buyers weighing nearshoring and tariff exposure.

Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements, including US-Mexico cross-border flows, do not appear, and product categories come from declared manifest codes, which are noisy. A small import record is not a sign of weakness for a domestically sourced stamper. Absence of a record is not evidence of absence.
