Microchannel Multiport Aluminum Serpentine Tube Bending Machine

Inquiry Form

This machine is specially for bending multiport / microchannel flat aluminum tubes into a serpentine shape for condensers and evaporators. It is comprised of a coil tube pay off strand, a straightening device, an automatic feeding device, an automatic bending head, and a stretch cutting device. It features PLC control and HMI operation, allowing the feeding length, bending radius and bending quantity to be preset on the touch screen. Also the parameters can be easily set and saved for future use. A high repositioning accuracy is guaranteed due to servo motor feeding and ball screw transmission.
