What is ultrasonic welding?
The technique of ultrasonic welding utilizes high-frequency ultrasonic acoustic vibrations. These vibrations result in pressure that develops a solid-state, durable weld. This welding process is used often for plastics, in particular to join materials that are dissimilar in nature.
As opposed to other methods of joining plastic, ultrasonic welding services develop a joint or bond area that is highly precise. The method achieved by state-of-the-art welding equipment ensures the exactness of every joint, something that is highly important for many applications.
How does ultrasonic welding work?
It only takes fractions of a second for a weld to be performed through ultrasonic welding. This type of welding utilizes ultrasonic waves to bond together precise locations on separate pieces of plastic and according to the customer’s exact specifications.
In this welding process, the ultrasonic waves, measured to the necessary frequency, vibrate the molecules in the specific targeted area. As the molecules are agitated, they produce heat, melting the exact location on both plastic pieces simultaneously. As pressures applied to both sides equally, the two areas are joined together and develop new molecular bonds. The applied pressure keeps the bond in place while the joined parts quickly cool and solidify.
Since electronic welding services do not require an external heat source, they do not change or impacting the strength or structure of the plastic around the joint. This process is viable for plastics that are similar or dissimilar to each other.
