Ducting Machines: The Backbone of Efficient HVAC Fabrication
Necessary Ducting Machines for HVAC Fabrication
- Autoline 3 Machine
The Autoline 3 machine is a cornerstone in duct fabrication, offering automatic coil feeding, cutting, beading, and folding in a single process. This fast system boosts productivity, making it an ideal choice for large scope duct manufacturing.
- CNC Plasma Cutting
Accuracy cutting is essential in ductwork, and our CNC plasma cutting machines deliver clean and accurate cuts for various metal thicknesses. With computer-controlled technology, you can achieve complex duct designs with minimal material waste.
- Rolling Machine
A rolling machine is used to form cylindrical and curved duct sections efficiently. Whether you need spiral channels or circular channels, they are suitable, our rolling machines ensure smooth and precise rolling for perfect air duct shapes.
- Lock Former Machine
The lock former machine is a key tool for creating high-quality duct seams. It forms Pittsburgh locks, snap locks, and other essential seam types to ensure airtight and secure duct connections.
- Lock Seam Closer
After forming the lock seam, a lock seam closer is used to secure and tighten the duct joints. This machine ensures leak-proof seams, improving the overall efficiency of air distribution systems.


- Elbow Maker
A duct elbow maker is essential for forming precise elbow sections in ductwork. It allows fabricators to create smooth bends for proper airflow direction, reducing resistance and improving HVAC efficiency.
- Folder Machine
A folder machine is used for bending and folding sheet metal to create duct sections with clean, sharp edges. It ensures uniformity and accuracy in duct fabrication.
- Grooving Machine
A grooving machine enhances the rigidity of sheet metal by adding reinforcement grooves. This process strengthens the duct panels, preventing deformation and extending their lifespan.
- Shearing Machine
For precise metal cutting, a shearing machine is an essential tool. It provides clean and straight cuts, ensuring perfect material sizing for duct fabrication.
- TDF and TDC Flanger
The TDF and TDC flanger is designed for forming flange connections on ductwork. This machine speeds up the assembly process and ensures airtight duct joints, reducing energy loss in HVAC systems.
