Auto parts sound insulation cotton and plastic welding machine

When the car is driving, it will generate a lot of noise. The external noise has a huge impact on the car. In order to reduce the impact of noise on the car, a large amount of sound insulation cotton is often filled in the frame. The main body of the sound insulation cotton is made of basalt. The main raw materials are melted at high temperature, made into inorganic fibers by high-speed centrifugal equipment, then added with special binder and dust-proof oil, laid felt with a swinging belt, changed the fiber arrangement structure through special equipment, and finally cured and shaped. Lightweight insulation.

Due to the difference in the shape of the car body, when filling the sound insulation cotton, the sound insulation cotton in multiple parts is often filled separately, and the contact parts of the adjacent sound insulation cotton are not in contact, which makes the connection of the sound insulation cotton cause contact offset over time. , so that there is no sound insulation cotton at the connection, which seriously affects the sound insulation effect of the vehicle. Therefore, a flexible welding structure suitable for the welding of automobile sound insulation cotton is proposed, which realizes the welding of the sound insulation cotton by ultrasonic welding.

The sound insulation cotton is welded firmly in the form of ultrasonic spot welding, replacing the original adhesive process. There are multiple sound insulation cottons for automobile wheel covers that need to be welded. According to customer needs, a non-standard automatic multi-head ultrasonic welding machine can be customized. Hand-held ultrasonic welding machine is used for welding. Repair welding.

Most auto parts manufacturers use multi-head ultrasonic non-standard equipment for welding, and hand-held ultrasonic welding machines can be used for repair welding for weak points.
