Advantages and Disadvantages of Ultrasonic in Auto Industry.
Advantages:
- Application in riveting, forming and welding
- Light weight, easy to take, easy to operate (handheld)
- Equipped with welding timer
- Easty to set time welding
- Equipped with an overload protection circuit( Voltage, current,
phase, temperature, output)
- FET power output
- Automatic resonance
- Maintain the amplitude function automatically
- Starting: achieving maximum power with 105msec
Disadvantages:
Limitation of measure, shape and material.(ultrasonic welding for
PP, PC, ABS, PA, PS, AMMA plastic).
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).
Components of Ultrasonic Welder
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.
