Electro-Discharge Texturing provides high quality textured surface in a range of 1,5 to 10mm Improved roll roughness consistency is achieved through high level process control of the EDT machine variables.

Benefits of EDT compared to shot blasting (SBT) :

  • Ra variation within a range of +/-5%
  • High peak count (Pc)
  • Lower waviness (Wa)
  • Improved strip control
