Sheet Metal Stamping Tolerances

At Wenzel Metal Spinning, our expertise lies in achieving precise spin-forming thickness tolerances and sheet metal stamping tolerances. With advancements in metal spinning technology and CNC spinning machines, Wenzel can now hold tighter metal spinning tolerances than ever before. However, metal spinning is not as exact as milling or machining. Wenzel Metal Spinning quotes a standard tolerance of +/- .060” unless otherwise specifically noted. Continue reading to learn more about our spin-forming thickness tolerances. 

Certain circumstances and part configurations such as shape, material type, and thickness lend themselves to other metal spinning tolerances. When working with metal spinning, the flat metal forms over a male tool. This means no part can be smaller than the machined tool, and thus in circumstances of very tight tolerances we can work with a + .060”/ > -.030”.

Spin Forming Thickness Tolerances

When it comes to spin-forming thickness tolerances, we acknowledge the natural thinning of material that occurs during the metal spinning process. While we do not provide a guarantee for the finished material thickness by default, our experienced team at Wenzel can guide you in determining an appropriate starting metal thickness for your project.

 G90 galvanized steel (ASTM653) is the best-galvanizedgal coating thickness for spinning and the industry standard for coating. For cosmetic applications, Wenzel offers galvanized steel that is very easy to paint or coat. Whatever your material or application may be, an experienced member of the Wenzel team will assist you in determining a starting metal thickness for your next project.
