Fully Automatic Die Forming Machine for die molded rings from 6 to 80 mm


The automatic Die forming machine model APM25 forms compacted die molded rings, of any shapes, using graphite strips or other similar materials having a diameter between 6 and 80 mm.

This forming machine can work in two modes

  • Semiautomatic where the operator feeds manually the pre-cut strips of graphite into the winding and inserting device. The ring manufacturing cycle is made in automatic by the machine including the ring ejection
  • Automatic (without operator) where all the cycle including the graphite feeding is performed automatically by the machine

Main machine features

  • Control system by PLC and Touchscreen Operator Panel to automatically control the manufacturing process and the gasket parameters
  • Pressing device made up hydraulic cylinder having 25 tons. pressing strength
  • Ejection device made up hydraulic cylinder having 1 ton. ejecting strength
  • Weighting device having a precision on 0,01 g that can check the real weight of each ring in order to separate the good ones from the rejected ones
  • Pressing strength adjustment by operator panel’s parameter
  • Motorised corrugation device
  • Automatic control of graphite strip length by means of encoder
  • Easy gasket program creation by means of the on-board wizard
  • Manufacturing Programs storage on SD card
  • Remote assistance
