KM-CFK

KM-CFK
Compacting station (resistance welding) for stranded wires from 0.5 – 6 mm² (20 – 10 AWG) for fully automatic crimping machines.

With the Strunk compacting station KM-CFK, stripped wire ends from 0.5 up to 6 mm2 (20 AWG up to 10 AWG) are compacted with a resistance welding process on fully automatic crimping machines of the CrimpCenter series. The system includes the KM-CFK station, a separate control unit and a separate (optional) cooling unit. The stripped wire end is positioned in the tooling of the compacting station by the swivel arm of the CrimpCenter.

Then the individual strands are compacted between vertically installed electrodes. On both sides, ceramic plates determine the compacting width. Change-over of electrodes and ceramic plates for different wire cross sections is easy and fast. Welding parameters can be monitored during the entire process and saved for quality checking when using the optional PC control unit.

Special Features

  • Reliable compacting of stripped wire ends / strands
  • Short cycle times
  • Easy changeover for different wire cross sections
  • Quality assurance with automatic data storage (PC-based controller)
  • Power amplifiers for mid- and high frequency available

Machine Configurations

Possible machine configurations and combination with crimping, sealing or other processes depend on the number of available stations of the CrimpCenter model.
