Company Technologies Products Sectors Services GREEN SONICS UL­TRA­SOUND Ultrasound is an innovative technology with many different applications in various areas. Because of its technical advantages, ultrasound is replacing many established technologies. Ultrasonic technologies are not only quick and efficient but also extremely eco-friendly for processing thermoplastics, films and fabrics. The principle of the technology is based on the generation of internal heat (molecular friction) by ultrasound and the boundary friction in the join or separation zones of thermoplastics. Ultrasound is mechanical oscillation at a frequency of approx. 16 kHz to 1 GHz. Sound of less than 20 kHz is perceptible by humans and is therefore described as audible sound. Frequencies of more than 500 kHz are hyper-sound. Ultrasound in the lower frequency range of 20 kHz to 100 kHz has industrial applications for plastics processing. The ultrasonic systems of SONOTRONIC operate at 20 kHz, 30 kHz or 35 kHz. The ultrasound frequency is produced by a generator. The generator converts mains voltage into high-frequency high voltage and transfers this to the welding stack, which is made up of the converter, the booster (amplitude transformation unit) and the sonotrode (welding tool). The converter converts the incoming voltage by electrostriction into mechanical oscillations of the same frequency and conducts them via the booster and sonotrode to the workpiece. Oscillation absorption, accompanied by the application of pressure and the vertical introduction of mechanical oscillations, creates interface and molecular friction in the joining or separation zone. The result is local heating of the workpiece material in the join zone. This plasticising process makes it possible for one or more workpieces to be welded, cut, punched, riveted or embossed, either continuously or in cycles . When processing textiles, fabrics can be washed by using ultrasound thermofixed by local heating. In addition, ultrasound offers a further application in environmental technology in the sonication of bio-solids: instead of local heating, ultrasound creates intensive cavitation bubbles. The implosion of the cavitation bubbles upsets the liquid so that, for example, the biological mass is better converted or disinfected. UL­TRA­SONIC WELD­ING One or more thermoplastic materials are connected to one another in the joining area during timed ultrasonic welding. UL­TRA­SONIC CUT&SEAL During the ultrasonic Cut&Seal process, materials are welded and simultaneously cut in one step. UL­TRA­SONIC ROLL SEAM WELD­ING Ultrasonic roll seam welding is suitable for continuous welding of large films, width fabric, non-woven or textile fabrics. The result is continuous welds without interruption. UL­TRA­SONIC CUT­TING Not only non-woven and textile fabrics, but also various foods can be precisely and cleanly separated or cut by ultrasound. UL­TRA­SONIC PUNCH­ING The patented ultrasonic punching from SONOTRONIC enables precisely defined openings of very high quality to be made in plastic components or textiles. In addition, the material can also be embossed or welded at the edges during the punching process. UL­TRA­SONIC RIV­ET­ING Ultrasonic riveting is suitable for the positive joining of thermoplastics together or to non-plastics. UL­TRA­SONIC EM­BOSS­ING During ultrasonic embossing, individual texts or logos can be “stamped”, for example on artificial leather or corsetry, with little force. UL­TRA­SONIC THER­MOFIX­ING Compared with conventional processes, ultrasonic thermofixing (UST) grants a far lower energy consumption, far smaller machines and an important reduction of the quantity of material inside the machine. UL­TRA­SONIC WASH­ING An innovation in the range of textile finishing is the energy-efficient ultrasonic washing of narrow fabrics and broadcloth. The principle of the new technology is based on cavitations and mechanic impact by ultrasound. SON­I­CA­TION OF BIOSOLIDS Biosolids as for example sewage sludge or biomass from renewable primary products, bring a definitely higher output if processed with ultrasonic tech. The effect is an intensification of the digestion process without the need to add chemical agents.
