Square Duct Machine

LOCFOME manufactures and supplies all machinery required for manufacturing square HVAC ducts. This ranges from basic duct lock forming machines (such as our Pittsburgh lock machine) to duct automatic lines. We can help you design and implement a complete and automated rectangular ductwork manufacturing solution and deliver the most fully formed straight duct and fittings possible.As a professional square duct machine manufacturer of square duct machine, we can give you our professional advice to help you get more reasonable match and choose the corresponding machines for saving cost and improving work efficiency.

Rectangular duct machinery mainly includes Duct auto-line, Plasma cutting machine, TDF flange machine (TDC flange machine), Pittsburgh lock machine, Duct seam closer (duct zipper), TDF hand folder and etc. All of these machines can complete duct sheet metal feeding, cutting, forming closing and duct joint connectors, fittings making.

This series of machines as part of air condition machine is always the most widely used in the air ventilation duct processing. It is widely exported to Southeast Asia, South America, the Middle East and other countries with stable quality, the most competitive price, and the comprehensive aftersales service.

LOCFOME has got a good reputation around our clients’ local markets.Such as duct auto-line,square duct machine and duct zipper. Most of our clients plan to build the duct manufacture factory; they just give us the new factory layout. We will design the complete solution for them, including the list of the machines their new duct factory need (according to their planned manufacture capability, output), and the electric circuit distribution (according to our machines voltage and the dimensions). You can contact us at any time if you have any question about HVAC duct machines. We will reply you and help you solve all problem as soon as possible.
Locfome Square duct machines are including Duct auto line, duct zipper, Lock former, TDF Flange machine, TDC Flange machine, Hand folder, TDF duct corner fitting machine, etc. The creatures are as follows:

1, Duct auto line
Duct manufacture auto line III is one of the most efficient machines for producing the air condition duct. It can uncoil the rolls, leveling, beading, cutting and bending the sheet for the next progress and final finish the production of duct.
It can cut fixed size sheet metal by CNC control system in bulk.
Also it can connect a plasma cutter at the end to do the fittings.
Material: used: GI and SS
Thickness: GI: 0.5-1.2mm SS: 1.5-1.2mm 4 units of 6 Ton capacity de-coiler
Leveling and grooving rollers
Hydraulic cutter
Hydraulic punching machine for punching

1, Punching C & S inserted cleat notch.
It can be used with C cleat and S cleat inserted flange machines.
Due to different connecting methods for notching and cutting, it can be used with a TDF Flange machine and TDF connecting machines.
On the other hand, it can punch TDC notch and fold metal for inserted flange, to produce square duct, for example, it can used with both combined seaming machine and inserted flange to manufacture a complete set of ducts.

2, Pittsburgh lock former
Material: used: GI and SS
Thickness: GI: 0.5-1.2mm SS: 1.5-1.2mm
Do the seam lock and S cleat and drive cleat.
The working speed is very fast

3, TDF (TDC) Flange machine
35mm TDF flange with 1.2mm thickness, and 0.8mm clip.
One side for TDF flange making, and one side for the clip.
20mm, 25mm, 30mm, 35mm, 40mm TDC flange work with Min 1.5mm thickness duct corner
It is recommended on large section area ducting as it is more durable and strong structure.
Hydraulic cutter makes cutting perfect.

4, Hand folder
For bending the rectangular ducts
Max 1.5mm GI sheet.
Easy operation.

5, Duct zipper
Material & Thickness: GI: 0.8-2.0mm SS: 0.8-1.5mm
This square duct machine can be work with duct auto line, duct zipper, TDF flange machine, and Pittsburgh lock machine. It is use Mitsubishi PLC control, with long time stable working ability and economic design, easy operation and easy maintenance. For closing the Pittsburgh lock at the last step. No need to use hammer all times only the head and the bottom, make the TDF duct flat and good looking.

6, TDF duct corner fitting machine
Material & Thickness: GI: 0.8-1.5mm
Air pressure: 0.6-0.8Mpa
This square duct machine can be work with duct auto line, duct zipper, TDF flange machine, and Pittsburgh lock machine This machine is for fitting TDF corners as a corollary equipment for duct auto line. Put the corner piece to appointed position, pressing and fixing automatically. Many kinds of corners are acceptable by this machine. T is use Mitsubishi PLC control, with long time stable working ability and economic design, easy operation and easy maintenance.
How long is the lead time?

TDF flange machine is integrated. With high speed, convenient operation and low air leakage ratio, it enjoys high population among customers. It saves material and labor cost, no welding is required.
