This Electronic Control System is able to administer precise control over expanding operation by automatically responding to the Torque Load on the Tube Expander.

​

The Control Unit cuts off the power supply to the expanding motor as soon as the motor current reaches to preset limit, resulting in uniform and precise expansion of all the tubes.

​

Each tube is expanded with optimum grip. No over-rolling, distortion or damage and operates without any guesswork and human errors, which results in superior quality of work.
