Car Soundproof Cotton Hand Held Spot Welding Machine With Hard Oxidized

The Ultrasonic Welding of The Car Soundproof Cotton Which Welding Head is Hard Oxidized

Definition of ultrasonic auto plastic welding:

Ultrasonic welding is a high-tech technology of sintered plastic products. The use of this technology can replace past production of flux, adhesives, buckles or other mechanical fixation, thereby improving the production efficiency and reduce costs. These welders combine technical sophistication with ease of use. They can be easily integrated in your production facilities. The principle of ultrasonic welding is through the ultrasonic generator to convert high-frequency electrical energy into higher frequency mechanical movement, then mechanical movement through a set of amplitude can be changed to the transmission device to the welding head. The welding head transmits the received vibration energy to the joint portion of the workpiece to be welded, in which the vibration energy is converted into heat energy by friction and the plastic is melted. Ultrasonic not only can be used to weld hard thermoplastics, but also can process fabrics and films. ALTRASONIC will find the best solution for your thermoplastic welding needs.

Conditions of Affacting Ultrasonic Welding:

Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature ultrasonic welding material viscosity flow temperature. Otherwise the material will not melt.
With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.3MPa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.
The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds. Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds. AMMA plastic).

Principle of Sound Barrier Contton Ultrasonic Welder

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 coagulation, so that to achieve the purpose of ultrasonic welding.

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.

Components of Ultrasonic Welding:

Horn, Booster and Transducer
Principle of Amplifying
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:

1.Titanium
high price, excellent performance good toughness and low loss, difficult to be processed;
Its amplitude can reach to 60mm.
2. Aluminum
low price, fast loss, easy to be processed;
Its highest amplitude less than 300mm.
3. 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.

FAQ:

1. What is ultrasonic puncture welding?

Ultrasonic puncture welding is only one kind of ultrasonic welding. It belongs to energy welding or destructive welding. It is widely used in auto industry.

2.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.

3.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. Many customers are concerned about material issues and also they care about how to design. There are some differences in the products of different ultrasonic puncture welding.

4.What are the three kinds of ultrasonic welding of auto soundproof cotton?

a . Hand-held ultrasonic soundproof cotton welding.

The soundproof cotton with hand-held ultrasonic soundproof cotton welding machine is widely used, low cost, simple operation but relatively hard labor.

Generally, there are two kinds of ultrasonic welding machines with hand holding and hand grip, which have 28K, 30K, 35K and 40K frequency.

b . Multi-head ultrasonic soundproof cotton welding

When the hand-held ultrasonic welding machine is not satisfied with the production of soundproof cotton, it can be welded with multi-head ultrasonic welding machine, the welding efficiency and quality can be improved, and the cost will be relatively high.

c . Soundproof cotton of robot ultrasonic welding

Robot soundproof welding, only requires one robot, one set of bottom mold tooling, and one set of ultrasonic components. The advantage of robotic soundproof cotton welding is that it can match multiple soundproof cotton products. It is only necessary to change the bottom mold tooling and robot program to improve the welding efficiency, and you can increase the robot, The disadvantage is that the one-time cost is relatively high.
