Automotive sound insulation cotton welding machines From cockpit filters and seat covers to trunk linings, sound insulation felts and carpet cloth, non-woven fabrics play an important role in the automotive market. Automobiles also replace rubber products and are widely used as rubber sheet reinforcement materials, compounded with rubber to make steel rim sheaths, automotive steering gear connecting rings, sealing strips, and modified rubber composites for use in mudguards and tire repair pads. , And in the floor. Non-woven fabrics are used more and more in automotive trim parts, and it is necessary to consider the connection of non-woven fabrics and automotive plastic parts. Among many welding processes, ultrasonic welding is better. Because ultrasonic welding is for non-woven fabrics: fast spot welding efficiency, good welding quality, no need for soldering materials, no burrs and easy forming, no pollution and safety.

Automobile sound insulation wool welding is hot melt welding using thermoplastic materials. It uses the principle of ultrasonic welding. Advantages of ultrasonic automobile sound insulation felt welding machine-welding can be completed within 0.1-0.5 seconds, fast and accurate, high work efficiency; mechanized production, product quality Stable and reliable; does not need glue, adhesive, screws to fix, saving cost; as long as the welding parameters are set, the operation is very convenient; the seam composition is the same as the base material, with high strength, good airtightness, no water leakage, and airtightness; surface Good forming, no damage or deformation, no scratches and adhesive residue marks.

The 30KHZ high-frequency and high-voltage electrical signal is generated by the ultrasonic generator, which is converted into the mechanical oscillation of the same frequency through the piezoelectric inverse effect of the transducer, and acts on the plastic product workpiece in the form of audio longitudinal wave, passing the surface of the workpiece and the inner molecules The frictional movement of the workpiece increases the temperature of the workpiece interface. When the temperature reaches the melting point of the workpiece itself, the workpiece interface quickly melts, and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time to achieve perfection Welding.

Application of ultrasonic welding machine for automobile soundproof cover
Car soundproof cover welding machine is specially used for welding car soundproof covers (car soundproof felt, car soundproof cotton, car soundproof board), after trimming and changing molds, it can also be used for welding car interior panels, car interior parts, car door panels, and car center panels , Automobile front cover and other automobile plastic parts.
The application fields of automobile sound insulation felt welding machine, automobile sound insulation cotton welding machine, automobile sound insulation board welding machine, and automobile interior trim panel welding machine are similar.
