Precision Metal Stamping Services

Our Precision Metal Stamping Process: Progressive Die, Deep Draw, and Prototype

AMG has been a metal stamping company since 1904. The current shop runs 20 stamping presses at our 75,000 square foot Mount Vernon, Ohio facility: 12 straight-sided machines from 80 to 300 tons, plus 8 OBI presses from 45 to 150 tons. The precision metal stamping process holds tolerances to ±0.001" on ferrous and non-ferrous sheet metal from .010" to .250" gauge. That precision feeds the automotive industry, heavy truck, agriculture, and the solar industry across the United States.

Progressive Die Stamping and Microstamping

Progressive die stamping handles most of our high-volume work. The progressive die runs strip stock through multiple stations of a single tool, with each stroke of the press performing one operation: blank, form, trim, draw, flange. Microstamping work for electrical connectors and small precision metal components sits at one end of the gauge range. Heavy-gauge structural stamping sits at the other. Compound and trim dies cover the simpler geometries between them, while in-house tooling keeps die change-overs measured in days.

Deep Draw and the Metal Forming Process

Deep draw metal stamping is the specialty for parts where the metal forming process pulls flat sheet metal into complex geometries without splitting or wrinkling. We run deep draws on cold-rolled steel, stainless, and aluminum. Tool and die work happens under the same roof as production, alongside sheet metal fabrication and assembly. Our in-house toolmaker team designs the punch, die, and supporting tooling for each part. Die corrections happen fast because the tool room and the press room sit 100 feet apart.

Prototype to High-Volume Production Runs

Prototype metal stamping moves from CAD review through first-article parts in our own tool room. Low-volume prototype runs give OEMs a way to validate geometry, material, and tolerance before committing production tooling capital. Once a design clears prototype, the same tooling scales into high-volume production runs of 2,000 to 50,000+ precision metal stampings per batch. Automation on the press lines drives accuracy and efficiency at scale. CMM measurement and statistical process control verify every production run, with 3D laser scanning available on complex parts where standard CMM probing falls short.

Custom Metal Stamping Services Across Industries

Custom metal stamping services at AMG cover the full design process: design-for-manufacture review, tool and die design, prototype runs, production runs, and secondary operations including welding, fabrication, washing, and assembly. Stamp, finish, and ship from one facility. Ford, Volvo, Stellantis, Toyota, Mack Trucks, Kenworth, and John Deere are stamping partners that work with us under this model. Our new solar industry stamping vertical applies the same playbook to solar OEMs that need domestic content documentation for a wide range of solar projects.
