It can support HVAC duct workshops and general sheet metal production when material type thickness cutting length accuracy and handling requirements match the verified machine capacity.
Hydraulic Duct Lock Seam Closing MachineA hydraulic lock seam closing machine closes a prepared longitudinal seam on rectangular HVAC duct sections using controlled hydraulic force and guided tooling. Correct selection depends on seam profile sheet material thickness duct length section geometry required tightness and production workflow.
Pneumatic Duct Lock Seam Closing MachineA pneumatic lock seam closing machine uses compressed air and matched tooling to close a prepared longitudinal seam on rectangular HVAC duct sections. Its suitability depends on seam profile material thickness duct length section geometry available air supply and required production cycle.
Duct Corner Punching MachineA duct corner punching machine uses a matched press and die to produce corner pieces or corner features for rectangular HVAC ducts. Correct selection depends on the required corner drawing material thickness die design press capacity production volume and downstream assembly method.
Duct Corner Code Assembly MachineAn automatic duct corner assembly machine positions and installs compatible corner pieces into the flange corners of rectangular HVAC duct sections. Correct selection depends on the corner drawing flange system duct dimensions material condition feeding method joining process and required production cycle
TDF Clip Cutting MachineA TDF clip cutting machine cuts prepared clip profile or sheet into connection clips used to secure mating TDF flanges on rectangular HVAC ducts. Correct selection depends on the required clip drawing input material thickness profile geometry cut length production volume power supply and site conditions.
Round to Flat Oval Duct Forming MachineA round to flat oval duct forming machine reshapes compatible spiral round duct into flat oval ductwork for HVAC systems. Correct selection depends on the round duct diameter finished oval width and height duct length material thickness seam construction forming method and required dimensional quality.
Hydraulic Round Duct Elbow MachineA hydraulic round duct elbow machine forms compatible edges on prepared elbow segments so they can be joined into round HVAC duct elbows. A dual workstation arrangement can support two tooling setups when the segment geometry material thickness seam system production mix and operating sequence are verified.
Automatic Round Duct Lock Seam MachineAn automatic round duct lock seam machine closes and strengthens a compatible preformed longitudinal lock on round sheet metal duct sections. Correct selection depends on seam profile duct diameter and length material thickness support method production volume required tightness and integration with upstream forming equipment.
Round Duct Grooving MachineA round duct grooving machine uses matched forming rollers to create beads grooves or approved edge profiles on round ducts and fittings. Manual and electric variants serve different workloads while suitability depends on duct diameter material thickness required profile roller design support method and production volume.
Bellows Tube Forming MachineA bellows tube forming machine reshapes a compatible straight round tube into a defined corrugated tube profile. Correct selection depends on the finished corrugation drawing tube diameter and length material thickness seam or weld construction forming method required mechanical performance and downstream connection process.
Round Duct Stitch Welding MachineA round duct stitch welding machine joins the prepared longitudinal seam of a round sheet metal duct using a controlled series of welds or a verified seam welding process. Correct selection depends on the joint drawing welding method duct diameter and length material thickness coating condition required strength leakage criteria and production volume.
CNC Angle Steel Flange Production LineFully automatic CNC production line for feeding, positioning, punching and cutting angle steel used in HVAC duct flange fabrication. Designed to reduce manual handling and support repeatable, efficient flange production.
Rivetless Sheet Metal Clinching Machine: Cold-forming sheet metal joining machine for creating permanent mechanical joints without separate rivets or screws, suitable for automotive, appliance, light-industry, precision machinery, electronics and hardware applications
HVAC duct fabrication may involve coil or sheet preparation, leveling, beading, notching, shearing, flange and lock forming, folding, seam closing and fitting production. The required machines depend on whether the workshop produces rectangular, round, spiral or mixed ductwork.
Selecting the correct equipment starts with the approved duct drawings, material grades, thickness range, duct dimensions, flange and seam systems, fitting types, production volume and workshop layout. Each function and capacity must be confirmed from the official documents for the selected machine.
What it is for
- Rectangular duct sections with integral flange
- Elbows, transitions, reducers and take-offs
- Spiral and round duct on the right configuration
- Site-ready sections cut from a drawing
- Repeat production for tower and mall contracts
How to choose
Match the line to your contract size
A line sized for tower work is idle capital on villa contracts. Tell us the monthly square metres you are actually fabricating and we size from that.
Gauge range decides which jobs you can bid
The thinnest and thickest gauge the line handles sets the specifications you are allowed to quote against. Check it against the consultant specs you normally see.
Floor space and material flow
These lines are long. Coil in, duct out, and somewhere to stack finished sections — the layout matters as much as the machine.
Insulation and sealing come next
Fabrication is one station in a sequence. Decide early whether insulation happens in your workshop or on site, because it changes what you need to handle and store.
Questions we are asked
What information is required to select HVAC duct machinery?
Provide the duct drawings, shapes, dimensions, material grades, thickness range, flange and seam systems, fitting types, monthly production target and workshop layout.
What is an automatic duct production line?
It is a coordinated production system that may combine verified operations such as decoiling, leveling, beading, notching, shearing, flange forming and folding. Actual functions depend on the selected configuration.
Should I choose individual machines or an integrated duct line?
Individual machines may suit varied or lower-volume production. An integrated line may suit a stable product mix and higher repeat output. The decision requires production and workflow data.
Can one line produce rectangular, round and spiral ducts?
Not necessarily. These duct types use different forming, joining and handling processes. The required machines and tooling must be selected for the actual product mix.
What site utilities may be required?
Requirements may include electrical power, compressed air, hydraulic systems, lifting equipment, coil handling, working space and storage areas. Exact requirements depend on the selected machines.
Are installation, training and warranty included?
Installation, commissioning, training, warranty, spare parts and technical-support scope must be defined in the approved quotation for the selected equipment.
