Machine Overview
This is a heat exchanger tube expander machine driven by a servo motor. The servo motor drives multiple sets of rollers to increase speed and torque output. The device can easily expand stainless steel and titanium alloy tubes.
Moreover, the expansion machine adopts a flexible design that allows users to quickly replace tools to adapt to different pipe diameters and spacing layouts. This flexible design can improve the efficiency of the factory and reduce costs.
The heat exchanger tube expander machine uses a PLC as the control center, and the parts of the control system come from internationally renowned brands such as Mitsubishi and Siemens. The system allows users to preset the production parameters of the product through a touch screen, and the control system presets various production modes.
