Ultrasonic plastic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. When applied to metals, a notable characteristic of this method is that the temperature stays well below the melting point of the involved materials thus preventing any unwanted properties which may arise from high temperature exposure of the materials.


 ♦Fully automatic frequency chasing, suitable for various sizes of welding die and different design mold, automatic chasing frequency range:±400HZ

Example: 15KHZ ultrasonic, mold frequency in 14.4-15.2KHZ can Automatic frequency traceability

♦The use of CPU computer to monitor various programs is fast and adaptable. The built-in protection system “system protection monitoring” function will respond to the following situations: the temperature is too high and the pressure is too high, which leads to overload. Excessive current of ultrasonic generator, loosening of solder head, transducer or transducer, failure of generator circuit, etc.

♦Automatic tuning enables the ultrasonic generator to automatically track and compensate for changes in welding head frequency. When the temperature is too high, wear on the surface of the welding head or debris on the head, this frequency change will occur.

♦Built-in automatic constant amplitude system. The ultrasonic amplitude can be adjusted from 50% to 100% stepless to adapt to different welding work.

♦With IGBT, the reaction speed is 100 times faster than that of traditional silica gel power tube.

The applications of ultrasonic welding are extensive and are found in many industries including electrical and computer, automotive and aerospace, medical, and packaging. Whether two items can be ultrasonically welded is determined by their thickness. If they are too thick this process will not join them. This is the main obstacle in the welding of metals. However, wires, microcircuit connections, sheet metal, foils, ribbons and meshes are often joined using ultrasonic welding. Ultrasonic welding is a very popular technique for bonding thermoplastics. It is fast and easily automated with weld times often below one second and there is no ventilation system required to remove heat or exhaust. This type of welding is often used to build assemblies that are too small, too complex, or too delicate for more common welding techniques.
