Metal Polishing for Nitrided Tooling and Steel Stamping Dies

Sun Steel Treating has specialized in Ionitriding® Class A Type 1 automotive body panel dies for over 40 years. These dies require polishing both before and after the nitriding process.  To ensure a proper finish, the Sun Steel Treating facility includes an in-house die polishing department.

Backed by decades of combined expertise in metallurgical engineering, Sun Steel’s integrated die polishing department helps your operation facilitate a more reliable and sustainable metal stamping process.

Complete Metal Finishing Services for the Die Stamping Industry

Our expert finishers can perform weld scaling, heat pop repair, as well as rough and finish polish before the Ionitride® process is applied. After Ionitriding®, our polishers will reproduce the polished surface finish of the die. Our polishers are experts in finishing all grades of cast iron and cast steel dies.
