Laser hardening in video

Mobile laser hardening of pressure sleeves

Mobile laser hardening on site of 14 meter long and 25 ton pressure sleeves that are used in large presses in an open-die forge and have to withstand extreme loads. By using the latest laser technology, we optimize the wear behaviour of these sleeves in a targeted manner.
