Round Pipe Spiro Tubeformer Spiral Air Duct Making Machine for Sale

Product Description

Product Description

Performance Features

The spiral duct making machine is designed for the efficient production of high-quality spiral ducts. These ducts are formed by spirally winding metal strip into a thin-walled, round tube—without welding and without air leakage. Compared with traditional manually-made "white iron" ducts, spiral ducts offer superior strength, sealing performance, and production efficiency. This fully automatic system eliminates manual tapping and ensures consistent, industrial-grade straight duct production.

Advantages
 1. Patented forming mold
Easy to adjust with a unique patented design, reducing mold-change time and improving material utilization.
 2. High-speed synchronous cutting system
Ensures clean, accurate, and efficient cutting at any production speed.
 3. PLC intelligent control
Provides stable, precise, and user-friendly operation.
 4. Suitable for on-site construction
Machine can be transported to the job site for direct installation and duct production.
 5. Flexible diameter adjustment
Rapid setup for different duct diameters without complex adjustments.
 6. High-quality product & service guarantee
Ensures stable performance and long-term reliability.
 7. Wide material compatibility
Capable of processing galvanized steel sheets, aluminum, and other duct materials.
 8. Automatic coil feeding system
Fully automated roll-out and feeding for continuous production.
 9. Multiple duct sizes available
Can produce a wide range of spiral duct diameters to meet various HVAC and industrial requirements.

CNC control system

This is the Human–Machine Interface (HMI), consisting of a touchscreen, control buttons, and function knobs. It manages auto/manual mode switching, start/stop control, speed adjustment, and emergency stop functions, serving as the central operation hub of the machine.

Feeding

This is the straightening and leveling roller section (also known as guide rollers or forming wheel box). Its primary function is to straighten, flatten, and guide the metal strip into the forming zone. It ensures accurate feeding without deviation and serves as a critical preforming process.

 Length Control Unit

 

This is the length positioning and measurement unit, designed to accurately set and monitor the forming length of the spiral duct. It is essential for maintaining precise product dimensions.

Electrical Control Cabinet

 

This is the central electrical control system equipped with Delta inverters, PLC, and key electrical components. It manages motor speed regulation, automated logic control, and operational protection of the entire machine.

Material Feeding Rack

This is the decoiler and material feeding rack used to hold and feed metal coils. It serves as the raw material entry point of the production line.
