Auto Plastic High Tech Ultrasonic Spot Welding Machine Gun Type / Cylinder Type
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.
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.
