Ultrasonic Welding For Plastics. Ultrasonic welding uses friction to heat plastics to a temperature high enough that theyll bond together. Ultrasonic welding is used for applications involving both similar and dissimilar joints as well as the welding of polymers.
In ultrasonic welding there are no connective bolts nails soldering materials or adhesives necessary to bind the materials together. As a general rule. When planning welds between semi-crystalline plastic work pieces it is important to remember that the welding behavior of these plastics differs considerably from that of amorphous plastics.
The process is based on a conversion of friction and vibration energy into heat.
Using a welding tool called a sonotrode the high-frequency vibrations generated by the ultrasonic system in combination with pressure are transferred to the parts. Using a welding tool called a sonotrode the high-frequency vibrations generated by the ultrasonic system in combination with pressure are transferred to the parts. The process is c lean because it doesnt use harmful solvents or glues while also not damaging the product. As a general rule.
