Product Service and Manufacturing

What Product Service and Manufacturing does

Product Service and Manufacturing, Inc. (PSM) is a privately held, family-owned contract manufacturer headquartered in West Milwaukee, Wisconsin, operating from over 79,000 square feet of manufacturing space across multiple Milwaukee-area facilities. The company was originally founded in 1973 and was purchased by the Westover family in 1984; it operates as a closely held corporation with no institutional investors and no public ticker. PSM is organized around three integrated business segments — precision machining, metal fabrication, and UL 508A-certified electrical panel wiring and assembly — which it bundles into a turnkey Complete Assembly offering for industrial customers. Capabilities span CNC machining to .0002" tolerances, weldments up to 100+ feet and 80,000 lbs, overhead crane OEM and rebuild structures up to 120 feet and 150,000+ lbs, and electrical controls including VFD, PLC, and Device Net integration. The company holds UL 508A, AWS D1.1, JCP, and SAM registrations and has won the Joy Global Premier Supplier Award for four consecutive years.

PSM generates revenue through project-based, quote-driven contract manufacturing engagements ranging from single-piece prototypes to multi-unit production runs. Pricing is fully quote-based with no public rate cards; customers initiate engagement via website Request a Quote form, phone, or email. The go-to-motion is sales-led and relationship-driven, evidenced by 10+ year partnerships with Rockwell Automation (panel assembly) and Konecranes (overhead crane OEM/rebuild), as well as recurring customers across industrial automation, mining, rail, oil and gas, government/defense, automotive, material handling, food service, HVAC, and wastewater verticals. The company maintains direct contracts with Military Sea-Lift, DLA, and the U.S. Navy on defense components. Marketing is limited to a content-led website, LinkedIn presence, and direct outreach — no resellers, marketplaces, or distribution intermediaries.

The business model centers on being a single-source vendor for electro-mechanical assembly, reducing multi-vendor coordination costs for industrial customers. Vertical diversification across 12+ end-markets is deliberate to smooth industrial cyclicality, while certified quality systems (UL 508A, AWS D1.1, NIST-calibrated metrology, 99.5% quality metric / 95% on-time delivery thresholds) and long-tenured skilled labor (30+ years electrical, 35+ years fabrication, 38 years material handling) form the operational backbone. Recent capital investment in 2024 OKUMA and HYUNDAI CNC equipment signals continued self-funded capacity expansion without external capital.
