Melt copper and aluminium together and cooling produces brittle intermetallics. Ultrasonic welding is solid-state, avoids the melt pool, and keeps them to a minimum.
Ultrasonic metal welding is a solid-state process: vibration and static force disperse the surface oxide so clean metal bonds directly, with the base metal never melting.
PP is semi-crystalline, with a narrow melting range and a soft surface, so joint strength and appearance pull against each other. Why the answer is not more energy but energy placed at the interface.
Whether two dissimilar plastics can be ultrasonically welded depends on two conditions: overlapping melt ranges and molecular miscibility. ABS and nylon as worked examples.
PEEK is semi-crystalline, melts at 343°C and has a narrow process window. Where the difficulty lies, and the three things that make reliable welding and sealing achievable.
Glass fibre attenuates the acoustic wave and reduces the resin available to fuse, so the surface scorches before the interface melts. The correct order of remedies.
Five technical handbooks, 68 pages in total, covering weldability assessment, staking joint design, amplitude selection, horn selection and energy director dimensioning.
The Dream S servo ultrasonic welding machine has completed conformity assessment to EU Machinery Directive 2006/42/EC, tested to EN 60204-1:2018 and EN ISO 12100:2010.
The quality management system is certified to GB/T 19001-2016 / ISO 9001:2015, covering production of ultrasonic equipment for both plastic and metal welding.
