Resonance unit SONIQTWIST®

The torsional ultrasonic welding process for demanding requirements

Advantages at a glance

  • Suitable for plastics and metal welding
  • Good accessibility, also in confined situations
  • No membrane effect
  • Gentle, low-vibration process, e.g. for sensors
  • For round and rectangular parts

The SONIQTWIST® torsional welding process developed and patented by Telsonic is an extremely gentle method of applying energy which significantly reduces the unwanted vibration input into the welded object. This makes it possible to also weld delicate products, such as sensors in a gentle process.

Applications and industries
Telsonic's torsional process is successfully used where the classical longitudinal ultrasonics technology reaches its limits. 

  • Welding and weld forming of thermoplastics
  • Cut-and-seal of textiles, fleeces and foils
  • Metal welding connections, with point and surrounding geometry
  • Low-vibration welding of electronic components
  • Producing the peel-off function, e.g. aluminium covers
  • Seal welding of aluminium packaging without plastic coating

SONIQTWIST® - characteristics and advantages

  • Good accessibility since only one vertical movement is required
  • Both round and rectangular parts can be welded
  • Suitable for delicate components, such as sensors, due to the low-vibration input
  • No membrane effect (unwanted melting and destruction), e.g. with foils and thin-walled parts
  • Firm welding on thin-walled visible components without visible marks on the other side
  • Compact melt formation and hence low particle formation (medical technology)
  • Reliable and leakproof weld seams, even with soiled joint seams
  • Possible to weld seams that are leakproof for helium
  • Strong weld seams
  • Short cycle times
