Review
Prints, CAD, scope, materials, tolerances, and timing are checked before quote assumptions harden.
Precision tooling and manufacturing since 1966
Tooling that makes complex production feel controlled.
Custom workholding, foundry tooling, aerospace machining, prototypes, build-to-print tooling, and custom manufacturing from a Wisconsin shop built around practical precision.
About Zeman
Family-built precision with modern manufacturing capability.
Founded in Waukesha in 1966, Zeman Tool & Manufacturing has grown from a small machine shop into a precision tooling partner for customers across the Midwest, the United States, and global manufacturing programs.
The company culture is grounded in trust, practical problem solving, and durable work. That shows up in the way projects move through engineering, machining, assembly, inspection, and final delivery.
Industries We Serve
Core services
Separate service paths, one coordinated shop.
Custom Workholding
Hydraulic, pneumatic, manual, 3-axis, 4-axis, 5-axis, tombstone, gaging, and testing fixtures built around the part, process, and operator.
Aerospace Tooling
Precision CNC machining for aerospace tooling and advanced alloys where stability, documentation, and repeatability matter.
Foundry Tooling
Permanent molds, low-pressure molds, tilt pour molds, static pour molds, sand cast patterns, and corebox configurations.
Precision Manufactured Parts
Prototype machining and precision manufactured components backed by CNC, EDM, grinding, assembly, and inspection.
Built-to-Print Tooling
Manufacturing for existing prints and CAD packages, with concept support, machining, assembly, testing, and finishing help.
Custom Manufacturing
A broad precision manufacturing equipment set with 3-axis, 4-axis, and 5-axis machining, boring mills, vertical milling, turning, welding, high-speed machining, EDM, grinding, assembly, and inspection.
How work moves
Review. Engineer. Build. Verify.
RFQs are clearer when the technical questions show up early: material, tolerance, datum strategy, fixture behavior, timing, assembly, and inspection requirements.
Engineer
Design intent is translated into a manufacturing and tooling approach that works on the floor.
Build
CNC, EDM, grinding, assembly, and testing move the project from plan to finished hardware.
Verify
Inspection and documentation make precision visible before delivery.
