In this video, we take a focused look at the specifications and what they mean in practice for the TF-1602 Spiral Ductwork Machine. You'll see a detailed demonstration of its hydraulically roll-and-shear cutting system that creates smooth, burr-free edges without sparks or noise. We'll walk through how the fixed mould system ensures precise, uniform duct dimensions and show the machine's high-efficiency operation for large-scale HVAC duct production. Watch to learn about its PLC control, automatic hydraulic functions, and how different mould sizes enable quick spiral angle adjustments for various duct diameters from 80mm to 1600mm.
