Assembly by energy applicator. Mainly reserved for amorphous thermoplastics. Ultrasound welding is done very quickly (less than 1 second), without adding material.
Ultrasonic spot welding
Ultrasound spot welding is particularly recommended for thermoformed parts without an assembly profile, or for parts whose geometry and actual conditions exclude the possibility of standard welding operations.
Continuous ultrasonic welding
Applied to high speed processes, continuous ultrasound welding is a solution for the high flow rates in the fields of packaging and non-woven textiles.
Ultrasonic riveting assembly
The main advantage of this process is that it allows to assemble parts of different types of plastic.
This technique encloses a part within a completely different material, by deformation of the material.
The penetration of metal inserts by ultrasound makes it possible to avoid the stresses due to overmoulding, to increase the injection rates and to simplify the production of injection moulds.
