2. System FRAD  (Full Range Automatic Die)

Automatic die adjustment with gap adjustment:
"Thermal Bolts" + mechanically, electromotive driven and controlled sliding wedge adjustment 

FRAD is a combination of two adjustment systems:

  • Mechanic adjustment of all thermal bolts with a sliding wedge system
  • "Thermal Bolts" utilizing thermal expansion of steel bolts


Bolts are heated with heating cartridges and chilled with air (external ventilation).
