06Ultrasonic Options
Sound enclosures, rotary tables and workstation options that complete your install.
Proven on production floors
Workhorses of the range.
Why ultrasonic
The fastest clean join in plastics.
High-frequency vibration converts to friction heat exactly where two parts meet — welding them from the inside out in well under a second. Read how the process works, where it fits and what it replaces.
About ultrasonic weldingSub-second cycles
Typical weld times of 0.1–1.0 s keep line rates high and energy use low.
Nothing added
No adhesives, solvents, screws or consumables — nothing to buy, cure or contaminate.
Repeatable by design
Digital generators track frequency and amplitude for consistent welds, part after part.
Clean and precise
Energy is delivered to the joint line only — no marks on visible surfaces, no heat damage.
Applications
Eight industries. One process.
