Ultrasonic welding is a process that uses high-frequency sound waves above the audible range to produce mechanical vibrations. These vibrations soften and melt materials at the joint line to join workpieces together under pressure.
The process is commonly used for welding thermoplastics and certain metals. Some of these metals include gold, silver, copper, and aluminum.
Orbital Fusion Technologies is a supplier of high-quality ultrasonic welding machines to meet your industrial needs.
Ultrasonic welding takes a few seconds at most, making it optimal for mass production.
Moreover, connective bolts, nails, solder or adhesives are not required in the process, reducing material costs.
Highly-targeted ultrasonic energy reduces the risk of excess electrical energy. The heat produced is minimal and will not damage the surrounding equipment.
It also does not require the use of flammable fuels and open flames.
Ultrasonic welding produces a clean and precise joint. As there are no filler materials and excess heat, contaminants are reduced.
The result is a durable bond with a smooth, appealing finish.
What does an ultrasonic welding machine consist of?
The machine consists of a machine press, generator, transducer, booster, sonotrode or horn, and component support tooling.
What is the frequency used for ultrasonic welding?
Ultrasonic energy at high frequencies (20 – 40kHz) are used to produce low amplitude mechanical vibrations (1 – 25μm).
How to choose an ultrasonic welding machine?
Selection of an ultrasonic welding machine can be considered based on the following:
