Progressive Stamping of Steel Laminations

Known for our high-quality progressive stamping services, Ramcel Engineering was contracted by a client from the automotive industry to produce a large series of stamped laminations used for electric power steering motor applications. With our 100-ton Minster press, which was able to run at 400 cycles per minute and hold overall precision tolerances down to ± .002, we stamped a full stack of 22 laminations within one operation.

Formed from M19 electrical steel, the Upper Rotors stack measured 1.457" in outer diameter and .897" in inner diameter, with a total material height of .393". Once all parts were completed and 100% inspected via a camera inspection machine, we custom packaged the finished units into anti-static plastic trays, which were then placed into cartons that were barcoded and labeled for delivery. All final items were shipped to our customer's facility in the Midwest.

Our advanced progressive stamping technology allowed Ramcel engineers to efficiently stamp 3,000,000 laminations, with weekly releases for this automotive industry client within a short, 2- to 4-week lead time.
