30 Khz Ultrasonic spot welder sound absorbing fleece (PES based) welding

Automobile sound insulation cotton is an important direction of automobile noise control. The sound-absorbing cotton is placed on the A-pillar guard plate, the B-pillar guard plate, the door panel guard plate, the middle passage, the wheel cover guard plate, the spare tire cover plate, the trunk, the engine cover, Car interior and exterior trim such as car main carpet. The connection between the sound-insulating cotton/sound-absorbing cotton and the plastic product is replaced by an ultrasonic welding process. Automotive sound insulation cotton / sound-absorbing cotton ultrasonic welding process has hand-held ultrasonic spot welding, sound insulation cotton professional welding equipment and robotic automated ultrasonic welding equipment.

Automobile sound insulation cotton includes sound insulation damping rubber, silencer insulation cotton, hood insulation pad, automobile sealing strip, wheel arc lining and so on.

The ultrasonic hand press offers a cost effective alternative to a standard pneumatic bench press. It is ideal for low volume production, offering an advantage over a hand held welder with its rigidly fixed welding head. The weld depth can be set giving consistent, repeatable results.

1.One key start, simple operation and easy to start with for customers.
2.Imported CPU and drive unit to ensure reliable power supply.
3.Effectively balance the amplitude while frequency is locked based on the frequency and amplitude control using PID.
4.Power outburst mode, save energy comparing to the traditional ultrasonic hand-held welding machine.
5.Welding amplitude adjustable from 60% to 100% by 1% step.
6.Dual-frequency mode, one can easily switch from one frequency converter to another by software configuration, the frequency setting range is ±8K.

Automotive sound insulation cotton / sound-absorbing cotton ultrasonic welding method:

1. Handheld ultrasonic spot welding
Manual operation, wide practicality and dexterous operation, it can be applied to the welding of sound insulation cotton for all automotive parts. Advantages: Low equipment cost and wide application; Disadvantages: low welding efficiency, low consistency of sound-absorbing cotton welding, and more labor (increased labor costs).

2. Soundproof cotton professional welding equipment (sound insulation cotton multi-head ultrasonic welding)
Plc+ touch screen control, multiple sets of ultrasonic welding components integrated on one device, one-button control, automatic welding. Advantages of the equipment: special equipment, high welding efficiency, beautiful appearance of the equipment, atmosphere, low difficulty for workers; equipment shortcomings: large one-time investment, and special equipment can only weld one kind of soundproof cotton plastic parts, low versatility.

3. Robotic automated ultrasonic welding equipment
Robot + ultrasonic welding system + welding tooling. High degree of automation, long used for welding small quantities of automotive plastic products. Advantages of the equipment: high versatility, can switch different welding bottom welding welding sound insulation cotton products according to different products; equipment disadvantages: robot ultrasonic welding equipment is a single point welding, only one point can be welded at a time, the welding efficiency of the equipment is lower than the special welding equipment.
