Ultrasonic welding of thermoplastic materials is a weld technology utilizing mechanical vibrations to generate heat due to molecular friction. These vibrations excite the molecules in the plastic so that they start moving. The plastic becomes soft and starts melting. The components are bonded by cohesive or form-fit joints After a short hold time under pressure, they are firmly joined molecularly.
Ultrasonic weld technology
Ultrasonic joining technology has been established as joining method for technical thermoplastic materials in a large variety of applications throughout the plastic-processing industry.
- high process speeds
- repeatable weld results
