Motor City Metal Fab is a fast-growing, family-owned precision fabrication shop in Southeast Michigan. Under one roof, we handle CNC machining, laser and waterjet cutting, welding, and powder coating—bringing complex ideas to life.
A day in the life
You clock in to a clean, well-equipped bay. An engineer hands you a fresh set of prints for a one-off assembly. You review the CAD, interpret the weld symbols and GD&T callouts, and map out your approach. You cut, fit, and tack components, then move seamlessly between TIG on thin aluminum and MIG on steel subframes. Midday, you collaborate with machining to tweak a feature for better manufacturability. By afternoon, your prototype is welded to tight tolerances, inspected, and finished—ready for feedback and iteration.
