Production of Ring Blanks

We focus our production on manufacturing ring blanks. To produce these blanks, flat material (different tool steels), which is perfectly adapted to the finished product, is bent into a ring. This vacancy is then connected permanently through a double pressure welding. By subsequent calibration tolerances in the range of 0.1 mm are achieved.

In this way, ring blanks ranging from 100 mm to 1000 mm in diameter can be produced. These ring blanks are machined and then applied in starter ring gears, flex plates, turntables, flywheels, gear rings, pulleys, ground rings, flanges and many other circular components. In our company about 2.5 million blanks are produced for the automotive industry every year.
