A spiral duct forming machine is a type of industrial machinery used in the HVAC (heating, ventilation, and air conditioning) industry to fabricate spiral ducts. The machine uses a unique process to form ductwork that is more efficient and cost-effective than other methods. The process involves feeding a strip of metal into the machine, which then cuts, rolls, and shapes the metal into a spiral shape. The resulting ductwork is very sturdy, energy-efficient, and can be customized to fit any building's specific requirements.
