CNG cylinder hot spinning machine
Description of CNG cylinder hot spinning machine:

Hot spinning is a new processing method for producing high pressure air cylinders because this processing method can increase surface quality and gently curvature of cylinders.

We pursue every detail on our hot spinning machine: spinning arm is mounted on a slide rail parallel to main spindle and so its rotary motion provides the best metal forming result.
