Air Duct Sewing Machines Our company has five types of air duct sewing machines, namely Seam Locker Closer Machine，Electric sewing machine，Pneumatic Locker Seam Closing Machine，Vertical Hydraulic Seam Closing Machine and Horizontal Hydraulic Seam Closing Machine。 Duct Locker Seam Closing Machine is a device specifically used for making and connecting air ducts.Its working principle mainly relies on the action of mechanical force and heat to joint two or more layers of thin steel plates, aluminum plates, and other materials under a certain pressure and temperature, forming a sealed air duct system. The following is a detailed introduction to the air duct joint machine: 1、 Components Rack: The main structure that supports the entire equipment. Seaming platform: used to place the air duct material to be seamed. Heating system: Heat up the joint platform to soften the material and facilitate the joint. Hydraulic system: used to adjust the pressure and temperature during the joint, ensuring the tightness and flatness of the joint. Electrical control system: controls the operation of the entire equipment, including starting, stopping, adjusting parameters, etc. 2、 Working principle Material preparation: Place two or more layers of duct material on the joint platform and adjust the position. Heating softening: Heating the material through a heating system to soften it, facilitating subsequent joint operations. Pressure sealing: The hydraulic system provides appropriate pressure and temperature to tightly fit the material under pressure, forming a sealed pipeline. Electrical control: The operation of the entire equipment is precisely controlled by the electrical control system, ensuring the stability and reliability of the sewing process. 3、 Advantages and characteristics Fast production speed: Compared to traditional manual production methods, the air duct stitching machine can greatly improve production efficiency. Good sealing effect: Through precise control system and mechanical force, the sealing effect is smooth, tight, and has good sealing. Material saving: Accurate cutting and stitching techniques can reduce material waste. Easy to use: The equipment is easy to operate, easy to learn, and reduces the skill requirements for operators. Widely applicable: suitable for the production and connection of various air ducts, including air conditioning ducts, ventilation ducts, fire protection ducts, etc. 4、 Application scenarios The air duct joint machine is widely used in factories, construction sites, decoration sites and other places that require the production and connection of air ducts. Especially in large-scale air conditioning and ventilation systems, the role of duct joint machines is particularly important. 5、 Future development trends With the continuous progress of technology and the growth of industry demand, air duct stitching machines are gradually developing towards intelligence and automation. In the future, air duct stitching machines may become more energy-efficient and environmentally friendly, while also having stronger applicability and flexibility. It is expected that there will be more technological progress and innovation, which will enable the air duct stitching machine to play a greater role in the air duct manufacturing industry. 1.Seam Locker Closer Machine Video presentation： 2.Electric sewing machine Video presentation： 3.Pneumatic Locker Seam Closing Machine Video presentation： 4.Vertical Hydraulic Seam Closing Machine Video presentation： 5.Horizontal Hydraulic Seam Closing Machine Video presentation：
