    Spiral Duct Forming Machine

    Spiral tubeformer for manufacturing straight round spiral air ducts or helical tubes

    • Structure: integrated type, suitable for transportation to the job site
    • Spiral duct diameter range: 100mm to 1800mm
    • Spiral duct thickness range: 0.5-1.2mm
    • Feeding speed: 35 meters/minute, adjustable

    Integrated type spiral duct forming machine is primarily designed for manufacturing spiral duct pipes used in commercial and industrial HVAC ductwork. It efficiently produces galvanized steel ducts (thickness 0.5-1.2mm) and stainless steel ducts (thickness 0.45-1.0mm) within a diameter range of 100mm to 1800mm. The applicable strip width for both materials is consistently 137mm. This spiral duct forming machine utilizes a direct-connect integrated structure, making the entire unit compact for easier transportation to the construction site for on-site duct production. It offers both convenient operation and efficient duct output.

    The main motor of the spiral duct machine provides 15kW of output, allowing for a maximum, adjustable feeding speed of up to 35 meters/minute, which supports high production efficiency. The spiral tube forming machine employs a die-forming process; compared to traditional spread-wing type duct machines, this method results in a tighter lock-seam and a more precise output diameter, ensuring consistency and reliability in duct formation.

    Uncoiler
    Uncoiler

    This steel strip uncoiling unit features a vertical, integrated structure connected to the main spiral duct forming unit. It is equipped with a pneumatic brake for controlled wear. A steel strip buffering device is equipped to prevent coil loosening and facilitate feeding. It supports coils with an inner diameter of 460-520mm, a maximum outer diameter of 1200mm, and a maximum load of 1100kg. Steel coils with excessively large outer diameters are not recommended due to the uncoiler's proximity to the main spiral duct forming unit.

    Cutting Method
    Rolling shear cutting
    Rolling shear cutting

    Provides a smooth, clean edge with no contamination, but requires re-adjustment of cutting angle and blade gap when changing dies or material thickness.

    Plasma cutting
    Plasma cutting

    Is suitable for any duct pipe diameter and thickness, but produces more smoke and dust during cutting.

    Rolling Mechanism
    Rolling Mechanism

    This spiral duct machine is equipped with two sets of rolling mechanisms, suitable for producing spiral duct pipes with thicknesses ranging from 0.5-1.0mm and 1.0-1.2mm, respectively.

    Forming Die
    Forming Die

    The spiral duct forming die is a fixed steel die with an embedded copper layer to enhance service life. The copper layer is replaceable, offering a cost-effective alternative to replacing the entire die. The forming die is wear-resistant, dimensionally accurate, and supports diameters from 100mm to 1800mm.

    Duct Support Rack
    Duct Support Rack

    The height of this duct support rack is adjustable. It features a pneumatic flipping function for supporting ducts under 500mm in diameter. Each rack can accommodate ducts 2-4 meters long, and multiple racks are available as an option.

    Wiper Board
    Wiper Board

    The wiper board is used to clean the surface of duct.

    Beader (Reinforcer)
    Beader (Reinforcer)

    Available in single-wave and double-wave styles, installed directly on the die. It is generally used to bead ducts with a diameter of 300-1000mm to increase strength.

    The DDGJ-1.2-1800-ZY (Integrated) and DDGJ-1.2-1800-ZF (Split) models are suitable. Both feature an adjustable feed speed of 35 meters/minute to ensure high production efficiency. They utilize a fixed steel die forming process, which results in a tighter lock-seam and more precise output diameter compared to traditional spread-wing type duct machines, effectively balancing the required speed and precision for mass production.

    Based on an 8-hour workday and accounting for material change time, the daily production capacity of spiral duct is 1000-1400 square meters.

    Due to the formation of the seam as a four-layer folded lock-seam, the resulting material loss rate is approximately 12.5%.

    Blades may become dull after multiple cuts but can be sharpened for continued use. Cutting stainless steel accelerates blade wear, so plasma cutting is recommended for that material. Emulsion fluid is the primary consumable.

    The spiral duct machine has minimal site requirements. It can be operated at the construction site or mounted on a vehicle for mobile production.
