Read MoreFAQ: Postprocessing
In ultrasonic welding, high-frequency vibrations are applied to the surfaces of two parts by a vibrating tool, commonly called a “horn” or “sonotrode.” Welding occurs as the result of frictional heat generated at the interface between the parts. The ultrasonic vibrations are created by a series of components—the power supply, converter, booster, and horn—that deliver mechanical vibration to the parts.

How to Solve Common Ultrasonic Welding Problems
Can Plasma Treatment be Used in Plastics?
In plastics, the most common plasma application is improving the bonding power of chemical adhesives; this can involve bonding metal to plastic, silicone to glass, polymers to other polymers, biological content to polymeric microtiter plates, and even bonding to fluoropolymers like PTFE.
Paint can have significant effects on mechanical properties of plastic parts. First, paint solvents may attack the plastic. In fact, it is often desirable for the paint solvents to attack (etch) the plastic to a certain extent, since this improves adhesion. However, solvents can also cause surface crazing, or even environmental stress cracking. In addition, paint solvents may cause swelling, softening, or dissolution of the polymer. Once again, a certain amount of this may help to promote adhesion, but taken to an extreme, it can degrade the properties of the plastic to unacceptable levels.
