Twin City Die Castings

What Twin City Die Castings does

Twin City Die Castings Company (TCDC) is a Minneapolis-based, employee-owned precision die casting manufacturer founded in 1919. The company operates three US facilities (Minneapolis, MN; Monticello, MN; Watertown, SD) totaling more than 184,000 square feet and running 19 high-pressure die cast machines (350–1000 tons) for aluminum and magnesium components, supplemented by in-house CNC machining including a HAAS UMC1000 5-axis center.

TCDC's offering is a vertically integrated die casting stack: Design for Manufacturing (DFM) review, custom multi-cavity tooling, high-pressure casting, precision machining, and value-added services such as deburring, sub-assembly, 100% camera/robot inspection, pressure testing, and packaging. Differentiated technical capabilities include thin-wall magnesium casting (e.g., 0.04-inch walls on the Fujifilm SonoSite X-Porte kiosk), proprietary flow simulation for thin ribs and tall bosses, and a documented ability to achieve cost reductions above 60% versus incumbent processes such as weldments.

Revenue is generated through project-based custom quoting for enterprise OEM and Tier 1 customers, with pricing determined by material, annual volume, and program timing under multi-year contracts. The company serves eight primary verticals: Automotive (the largest at ~50% of revenue, with EV/ADAS repositioning), Medical, Defense (ITAR compliant), Powersports and Recreational Vehicles, Industrial Products, Computer Technology, Hand Tools, and Renewable Energy. TCDC is IATF 16949, ISO 14001, and ISO 45001 certified across all sites, is a founding member of NADCA and a member of IMA, and transitioned to 100% employee ownership via an ESOP in December 2017.
