Using Multihead Ultrasonic Welding Machine for Mud Guard and Soundproof Cottom

Using Multihead Ultrasonic Welding Machine for Mud Guard and Soundproof Cottom 

Description: 

The ultrasonic welding machine of mud guard and Soundproof cotton, the ultrasonic technology is used to weld the two cotton with ultrasonic puncture technology, which is used to weld the auto wheel cover and replace the original binding process. The ultrasonic welding is stable, and the sound insulation effect of loading test meets the standard.Front and rear wheel covers also need ultrasonic welding, you can use a handheld ultrasonic welding machine for welding, also can use multi-head ultrasonic welding or robot welding if large quantity, compared to handheld ultrasonic welding machine, it is low cost and durable.

How to use ultrasonic puncture welding technology?

It was decided by product material, best of same material, or a mixture of materials and other materials. It depends on whether the ultrasonic wave of two kinds material can be fused. You can send the material to try to test. 

How to design ultrasonic puncture welding?

Usually it is up and down welding. The characteristics of puncture welding, there will certainly be a scar on one side, the other side may not be seen if thickness. Many customers are concerned about material issues and also they care about how to design. Here we share the actual ultrasonic puncture welding cases. There are some differences in the products of different ultrasonic puncture welding. The content is for reference only.

Specifications:

Gun and Cylinder Type of Horn

Gun type: in accordance with the shape design of human body engineering, ultrasonic start switch is located on the trigger, easy to grasp and use the welding operation, especially suitable for horizontal or vertical.

Cylinder type: for the appearance of design straight, ultrasonic start switch is located outside the cylinder, easy welding and hand carried, can also be installed between the on machine, welding operation for each direction.

Principle of Soundproof Barriers Spot Welding:

When the ultrasonic role in the thermoplastic plastic contact surface, it will generate tens of thousands of times per second, high frequency vibration, this high-frequency vibration, ultrasonic energy through the ultrasonic wave transmitted to the mold to ultrasonic welding material surface, it will produce high-temperature materials. Plastic contact surface resulting in rapid melting, coupled with stress, it blend and 

Components:

Components of Ultrasonic Welding (Horn, Booster and Transducer)

They can amplify the amplitude at a particular ratio step by step. For example, the transducer amplitude is 6mm, the booster can amplify it triply to 18mm, and then the horn can make it to 36mm. However, the work life of horn would be shortened with the amplification of amplitude. The required amplitude differs with the welding material.

There are three common horn material:

Titanium

high price, excellent performance good toughness and low loss, difficult to be processed;

Its amplitude can reach to 60mm.

Aluminum

low price, fast loss, easy to be processed;

Its highest amplitude less than 300mm.

Steel

too hard to be made as horn;

its highest amplitude less than 25mm;

It is suitable for cutting but the blowpipe need to be added in for its cooling.

Applications In Automobile:

Ultrasonic Spot Welding is mainly used in automotive interior parts. Ultrasonic spot welding in sound-proof cotton of engine cover, trunk and wheel casing, and hallstand felt. Ultrasonic Riveting Welding can be used in automobile air-conditioning outlet welding, car rear view mirror, car door handles, hand car door and so on.

Automotive plastic parts are mostly welded in non-standard ultrasonic welding equipment, long multi-station design, with PCL program control and LCD operation, large automotive complex workpiece welding, including different directions of the welding surface, in multiple locations.
