The spiral duct forming machine is mainly used for making round spiral air duct. Adopting duct mold structure, this machine is faster with more coincident diameter than traditional steel strip type spiral duct making the machine. The length of duct cutting can be controlled according to your own requirement with perfect cutting effect. Cutting method is non-noise cold shearing. The shrimp elbow machine adopts vertical working table with the switch of single side and bilateral sides. Advantages of this machine are the easy operation and perfect effect. This machine can roll angle steel and flat steel according to the fixed size to meet the production of round duct flange sides.

Round duct is manufactured with various seam types, the most common being spiral or snap lock. Round duct is used to connect between fittings, accessories and flex duct. Manufactures usually stock standard lengths, but if you have your own spiral machine you can fabricate any length. Round duct making machine consists of four types, including electric rolling machine, round duct lock forming machine, round duct lock seaming machine and round duct grooving machine. All these machines can make a complete round air duct.

Auto duct production line is a duct-making line with the highest automation and highest efficiency in rectangular air duct production line machines. The air duct production line machine can help customers to finish all needed processes from cutting sheet metal to forming the whole duct under the control of the auto system. An automatic control system greatly improves the precision and the beauty. Auto duct production line includes auto duct line 2, auto duct line 3, auto duct line 4, linear auto duct line 5, and U shape auto duct line 5.

Rectangular duct making machines mainly includes CNC plasma cutting machine, angle steel flange cutting and punching production line, TDF flange forming machine, lock forming machine, folding machine, grooving/ beading machine, shearing machine, lock seam closing machine, etc. This series of machines is the product with the biggest demand for air ventilation duct processing. All of these machines can complete duct sheet metal feeding, forming and duct installation parts making. Before starting to open machines, the worker has to strictly check equipment performance and safety according to requirements. Besides, please pay attention to add lubricating oil to ensure the efficient operation of machines during the using of products.

A round duct machine consists of four types, including an electric rolling machine, round duct lock forming machine, round duct lock seaming machine, and round duct grooving machine. All these machines can make a complete round air duct. Round duct is manufactured with various seam types, the most common being spiral or snap-lock. A round duct is used to connect between fittings, accessories, and flex duct. Manufactures usually stock standard lengths, but if you have your own spiral machine you can fabricate any length.

Gorelocker/Elbow making machine is specially designed for elbow tube forming in both elbow pittsburgh and seaming. The advanced gorelocker is 100% gear driven without belts at all that ensures good quality and much better durability.
