Locking machine is necessary in duct area because it can produce all kinds of types to meet locking requirements. Standard machine can process 0.5-1.5mm galvanized sheet metal, and our company would specially introduce high-strength rolling reels made of GCr15, a kind of steel which prolongs the machine life by more than 5 times and improve the efficiency dramatically.
Essential Equipment for HVAC Air Duct Manufacturing: The lock forming machine is crucial for HVAC air duct manufacturing. Multi-function lock forming machines can form 6 shapes (7-function is available) to complete sheet jointing.
Shape Forming Capabilities: Six standard shapes include Pittsburgh (Female), Right angle (Male), Standing seam, C shape locking pin, Curving angle, and Z shape. Customizable shapes such as S shape and snap lock for sheet locking are also available.
Material and Thickness: The standard duct fabrication equipment handles 0.5-1.5 mm thickness galvanized sheet. Two models are available: one with a max thickness of 1.2 mm, and another with a max thickness of 1.5 mm.
High-Strength Rolling Reel: We use high-strength rolling reels made of GCR 15 steel, which prolongs machine life by more than 5 times and greatly increases efficiency.
Types of Lock Forming Machines: Square duct lock forming machines are part of rectangular ventilation air tube forming machines and can be used with other rectangular HVAC duct forming machines like TDF flange forming machine, pneumatic TDF sheet metal folding machine, grooving machine, electric cutting machine, square duct lock seam closing machine, and clips cutting machine. Round duct lock forming machines can be used with electric rolling machines, round duct lock seam closing machines, bead rollers, and more.
Comprehensive Machine Series: BLKMA offers both CNC duct production lines for automatic air duct manufacturing and separate machines that are easier to move.
