Condition of Ultrasonic Welding of Door Panel
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.Pa (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).
Classification of Ultrasonic Welding
Ultrasonic welding: ultrasonic vibration with ultrasonic welding mould, the ultrasonic welding energy conduction to the plastic surface, resulting in local temperature, so that the plastic surface melting. Under the pressure of the ultrasonic hand, so to weld plastic, beautiful, strong effect.
Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.
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
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:
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 is the ultrasonic welding machine of mud guard and soundproof cotton?
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.
