Automatic Copper/ Aluminum/ Bundy Tube Reducing Machine

The machine handles tube loading, transfer between stations, rotary forging, necking, blanking, and part ejection without operator intervention. Pneumatic gripper jaws move workpieces through each stage in a coordinated linkage sequence, keeping cycle times short and labor requirements low.

Engineered to reduce copper, aluminum, and Bundy (double-wall brazed steel) tubes — the three materials most commonly specified in refrigeration circuits, heat exchangers, and automotive fluid lines. Tooling and forming parameters are adjustable through the HMI to accommodate different tube diameters and wall thicknesses.

The rotary forming method applies force evenly around the tube circumference, producing concentric, uniform reductions with tight dimensional tolerances. This results in leak-free joints and reliable downstream assembly, whether tubes are brazed, flared, or press-fitted.

The touchscreen panel lets operators input tube specifications, save recipes, and recall them for repeat jobs. This reduces setup time between production batches and minimizes the skill level required to run the machine at full capacity.

A heavy-duty steel frame, linear guide bearings, and enclosed forming area ensure stable operation under continuous production loads. Safety interlocks, emergency stop controls, and a multi-color signal tower keep operators informed and protected throughout every cycle.
