Jaw expansion is used to increase the cross-section of a tube (round, square, rectangular...) of different materials (steel, stainless steel, aluminum, copper...), in order to fit it into another or to calibrate it to a precise dimension.
Tube jaw expansion is mainly used to crimp 2 parts together.
We design and manufacture autonomous, manually-loaded tube jaw expansion machines as well as fully-automated, CNC-controlled punching machines, from the input magazine. The bundles of tubes can be loaded in automatic loader. The tubes can be unloaded automatically. Our tube punching machines adapt to your needs as well as your budget. Tube punching is often combined with one or more other operations (tube end forming, swaging, sawing or shearing, notching, forming, marking, etc.).
Advantages of jaw expansion :
- calibration of internal dimensions
- crimping solution that's faster and cleaner than welding
