Condition of 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.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).

Portable Ultrasonic Auto Door Spot Welding Principle:

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.

Components and Different Material Type of Horn

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.
