Advantages and Disadvantages of Ultrasonic in Auto Industry.
Advantages:
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.
Attention of Ultrasonic Welding
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).
Portable Ultrasonic Auto Rear Mirror Welder 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.
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 and Amplifying Principle
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.
