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).
