1. Ultrasonic systems allow to weld the edge of fabric in one single operation ! Our technology is based on the piezoelectric principle, to transform an electrical signal in mechanical vibration.
2. These oscillations will be amplified by the booster and converter, thus creating a hammer. The converter converts electricity into high frequency mechanical vibration. The active elements are usually piezoelectrics ceramics.
The booster (optional) serves as an amplitude transformer. Amplitude magnification or reduction is achieved by certain design features or the geometrical shape of the booster.
3. The sonotrode, or horn, is the active part of the ultrasonic unit. It is in contact with the fabric and acts as a hammer against the counter-tool. This system will enable to melt the fibers within the fabric by mechanical action only (hammering), enabling to obtain a very clean and flexible melting without any burning or color change. The sonotrode and counter-tool design will be adapted to the operation to be performed.
4. Advantages: repeatable results, quick cooling and easy hermetic sealing ; frequencies available include 15kHz,20kHz, 30kHz and 40kHz for any size job, from the smallest electronic components to large scale instrument panels in the automotive industry; a smooth, clean joint; save money with quick drying times and fewer raw materials.; no separate screws or other fasteners and never need touch-ups.
