Roll shear of ST125

Spiral duct machine cut edge

The cutting edge is smooth and clear.

So far as we know, the saw blade cutting system will worn out after few days of cutting, and also the saw blade cut end is not smooth like shear, and the most important thing is the noise, it is really noisy when cutting the spiral duct, so our engineers developed the latest plasma cutting, which is now available on ST80 and ST125.

Spiral duct machine plasma cutting

With the help of our spiral duct machine, you can make the beautiful surface spiral duct, the special designed system can make the joint tight enough to bearing the air pressure through the duct.
The 0.5mm material can make the 100mm diameter duct which can endure 1677Kpa, more technical you can check: max air pressure through spiral duct.pdf
