1. The main motor, forming machine and traction machine are all controlled by frequency conversion speed regulation, which is energy-saving, stable in operation and low in noise.

2. The tube blank diameter measurement adopts CCD chip and MCU micro-processing chip, which is controlled by PWM signal, with fast speed, high reliability and stable control.

3. The forming wheel is made of high-quality stainless steel, which is corrosion-resistant and has a long service life.
