The following are specific applications for some devices

The air duct automatic seaming machine can complete the last step of the air duct—the joint seam only by putting the finished air duct into the vertical joint sewing machine, and the manual tapping is unnecessary. The air duct automatic seaming machine can complete the last step of the air duct—the joint seam only by putting the finished air duct into the vertical joint sewing machine, and the manual tapping is unnecessary. Under general situation, there are three types of duct locks are more common, they are button lock joints, Pittsburgh lock joints and duct zipping joints. Among them, the Pittsburgh lock joint connection method is the used more widely. The vertical air duct seam closing machine developed by our company, to automatically completes the seam closing of duct.

The folding machine is a air duct processing machine specially designed for folding the ventilation of the common duct with flange. It can be accurately bent into an "L" or "square" type air duct, which can not only fold the air duct of the common flange, but also can be folded in general ducts without flanged, it can be used in sheet metal and bending work in various industries.

The series of machines are rugged, fast and precise, with no special maintenance and has long service life. The machine uses heavy-duty chassis, arc welded steel frame, high-quality motor, high-precision bearing, quenched and rounded roller shaft, maintenance-free transmission system, and the surface of the frame is painted and easy to move, suitable for on-site construction. 

There are two types of spiral duct machines, one is steel strip forming type, and the other is mold forming type spiral duct machine. The steel strip forming type spiral duct machine can process different sizes of the spiral tube by adjusting the steel strip in the machine and replacing different sizes of the steel strips, which is easy to change and adjust, and does not require much manpower and material resources. Steel strips are relatively cost-effective to manufacture spiral ducts. The spiral duct machine has advantages of fast processing and stable performance and processes spiral ducts with good sealing. The mold type spiral duct machine adopts a fixed shaping mold, and replaces different size molds to form different sizes of spiral tubes, so that the size of the air duct is more precise and uniform, the tube size is stable, the sealing performance and the forming effect are good, and the forming process is more stable and quick. According to different requirements of the cutting length of duct, high-speed synchronous automatic roll cutting and cutting device can be adopted.
