The automobile ultrasonic sound-absorbing cotton and sound-absorbing cotton felt ultrasonic welding technology is widely used in the automobile industry. There are automobile trunk spare tire cover sound-insulating cotton, automobile center console sound-proof cotton, automobile engine cover noise-proof cotton, automobile trunk sound-proof cotton, Ultrasonic welding of automobile wheel covers, soundproof cotton, etc. Replace the original adhesive rubber insulation process with ultrasonic technology. The ultrasonic sound insulation cotton welding machine includes hand-held ultrasonic welding machine manual spot welding, multi-head ultrasonic welding machine and robot ultrasonic welding machine.

Automobile sound insulation cotton welding is similar to automobile sound-absorbing cotton, automobile sound insulation felt, automobile vibration isolation pad, automobile sound insulation block silencer block, automobile non-woven insulation pad, automobile sound insulation board, automobile carpet, automobile cotton felt and the like.

Three ways of ultrasonic welding of automobile sound insulation cotton

1. Handheld ultrasonic sound insulation cotton welding

Welding soundproof cotton with hand-held ultrasonic welding machine is widely used, low cost, simple operation, and relatively laborious.

There are two types of ultrasonic welding machines, hand-held and hand-held, with 28K ，30K，35K and 40K frequency.

Ultrasonic molds are generally made of aerospace aluminum, and the surface of the mold can be hard oxidized to be more wear-resistant.

2. Multi-head ultrasonic sound insulation cotton welding

When the output of the sound-insulating cotton can not be satisfied by the hand-held ultrasonic welding machine, it can be selected by welding with a multi-head ultrasonic welding machine, the welding efficiency and quality can be improved, and the relative cost will be relatively high.

The multi-head ultrasonic welding machine can use domestic or imported systems. The more the corresponding generators, the shorter the welding time. The welding heads with relatively close distance can be welded with ultrasonic mother-child. The defect of the multi-head ultrasonic welding machine is that it cannot match other sound-insulating cotton welding products.

3. Robotic sound insulation cotton ultrasonic welding

Robotic sound insulation cotton welding requires only one robot, one set of bottom mold tooling, and one set of ultrasonic components. The advantage of robotic sound insulation cotton welding is that it can match multiple sound insulation cotton products. It only needs to change the bottom mold tooling and robot program to improve the welding efficiency. By adding robots, the disadvantage is that the one-time cost is relatively high.

Automobile sound-insulating cotton and sound-absorbing cotton are widely used in the whole automobile. Nowadays, they are basically welded by ultrasonic technology. At the beginning, they are first welded with a hand-held ultrasonic machine. The output will be selected by ultrasonic multi-head welding machine or robotic ultrasonic welding machine. . The specific process should be selected according to the actual situation of the customer.
