Cross Flow Fan Blades Plastic Welding Machine for Air Conditioner Blower

　　Cross Flow Fan Blades Plastic Welding Machine for Air Conditioner Blower is a device specially designed to weld fan blades made of thermoplastic plastics. This type of machine uses ultrasonic technology to generate heat through high-frequency vibrations, which melts and combines the plastic contact surfaces, thereby achieving fast, strong and well-sealed welding results.

　　Working Principle

　　When ultrasonic waves act on the contact surface of thermoplastics, they generate high-frequency vibrations tens of thousands of times per second. This high-frequency vibration with a certain amplitude will transfer ultrasonic energy to the welding area, and due to the large acoustic impedance at the welding interface, high temperatures will be generated locally. In addition, the plastic material itself has poor thermal conductivity and cannot dissipate heat in a short time, so that the welding area can heat up rapidly, causing the contact surface of the two plastic parts to melt rapidly. Under the application of a certain pressure, these melted parts merge into one; when the ultrasonic waves stop, continue to apply pressure for a few seconds to solidify it, and finally form a strong molecular chain with a strength close to the raw material itself, completing the welding process.

　　Technical Parameters and Specifications

　　Depending on the manufacturer and model, the technical parameters of these welding machines will also vary. For example, there is a customized cross-flow fan blade welding machine for air conditioner blowers, which has dimensions of L1300mmW150mmH1900mm, is suitable for plastic welding, and provides a one-year warranty service. In addition, the operating frequency of the equipment is 15KHZ, and the welding area ranges from 60 to 130mm.

　　Application scenarios

　　This type of welding machine is mainly used to manufacture or repair cross-flow fan blades in air-conditioning systems. They can ensure that the connection between fan blades is firm and reliable, which is essential to ensure the performance of air-conditioning systems. Especially in split air conditioners, cross-flow fans are widely used in indoor units as part of air supply devices.

　　Advantages and characteristics

　　High efficiency and energy saving: Compared with traditional welding/bonding processes, ultrasonic plastic welding has the characteristics of faster speed, lower cost, and cleaner and pollution-free.

　　High stability: All parameters in the entire welding process can be tracked and monitored by the software system. Once a fault is found, it is easy to eliminate and maintain.

　　No damage to the workpiece: Since only the welding part is heated, no damage will be caused to other parts, ensuring the integrity and aesthetics of the product.

　　High-quality welding: fast welding speed, high strength, good sealing, and can reach or even exceed the strength level of the raw materials themselves.

　　Market selection

　　There are many different types of cross-flow fan blade plastic welding machines available in the market. Some are fully automated, such as the automatic tangential cross-flow fan blade ultrasonic plastic welding machine, which is designed for air conditioner impeller blade stacking assembly; others are semi-automatic, allowing operators to have more control. For companies with specific application needs, customized solutions can also be considered to meet specific design and technical requirements.

　　In summary, the cross-flow fan blade plastic welding machine not only improves production efficiency, but also ensures product quality, becoming an indispensable part of modern manufacturing. If you are looking for such an efficient welding equipment, be sure to contact a professional supplier for more information and support.
