Automatic Condenser Core Wire Tying Machine
I Description of condenser core wire tying machine:
This machine is specially designed for tying radiator & condenser cores with steel wire automatically.
This machine adopts servo motor feeding steel wire, mechanical clamp tying wire and servo motor reversing wire to tighten.
The machine is PLC control, HMI operation. There is only manually loading blank cores onto movable table and unloading tied cores from movable table. All other actions will be automatically finished.

V Benifits of wire tying for brazing cores
* Wire elastic properties reduce compression buckling of fins during brazing
* Elimination of model specific brazing jigs
* Elimination of brazing jigs storage areas frees plant floor space
* Elimination of brazing jigs maintenance labor and costs
* Reduced furnace energy cost
* Increased furnace throughput
* Increased furnace conveyor belt and muffle life
* Wire Tying machines eliminate the use of brazing jigs for brazed heat exchangers. Process cost reductions include:
- Braze jig cost elimination
- Furnace throughput increase
- Furnace energy reduction
- Improved braze quality
