1- What is ultrasonic welding? How does ultrasonic welding work? First, an ultrasonic generator produces an electric current with an approximate tension of 1000V, a frequency of 20, 30, 35 or 40 kHz, and a 1A intensity. Then, the generator delivers the electric current through an ultrasonic cable until a ceramic made converter. The ceramics vibrate at the chosen frequency (20, 30, 35 or 40 kHz) and generate a few microns amplitude. The converter then generates positive and negative vibrations and transforms the electric current into mechanic energy. Afterwards, a sonotrode in steel or...

Are there multiple types of ultrasonic welding? At Cera Engineering, ultrasonic welding can be two types: - Static welding (intermittence welding) Continuous welding (rotary welding) You want to learn more about this technology? Please check out our new website: http://www.cera-groupecera.com/en/ Beyond our rotary welding and on-drum welding solutions, our customized static welding module enables you to assemble without any thread, needle, glue, nor any added fabric, thermofusible materials while keeping the resistance of your finished product.

3- Continuous ultrasonic welding expertise At Cera Engineering, continuous ultrasonic welding can follow two models: Continuous ultrasonic welding with rotating sonotrode and wheel In this case, the sonotrode is made of steel or titanium, and has a tulip shape (what enables to work on a 8 to 12mm width) or is a “double bearing” one (what enables to work on a 45mm width). The latter type of sonotrode makes the process more rigid, more solid and strictly parallel. Opposite to the active face of the sonotrode, an avril turns by 0 to 45mm width. Here, the drum and the sonotrode are turning in...

Continuous ultrasonic welding with a fix sonotrode and a turning drum In this case, a fix sonotrode faces the drum, with a 20 kHz frequency. In some applications four sonotrodes are facing the drum, so as to work on 0 to 800mm widths. Here, the drum turns while the sonotrode is fixed. This second type of continuous ultrasonic welding is used on our special machines and on our machines to manufacture gloves, which can reach an 80m/min production capacity.

4- Cera 520, direct welding of the ribbon on the slide axis Economical and efficient When designing the Cera 520, our goal was to supplement ultrasonic welding with an efficient technology, and to integrate the highest performance and precision into the smaller possible machine. Producing up to 1200 pieces per hourwith 30 kHz sonics, while giving the operator the possibility to control up to 4 machines, the Cera 520 allows to manufacture in quantity high quality products, without fraying, yellowing nor adding further fabric. Through its new design and high technology, the new Cera 520...

5- Cera UltraSonic (Ultrasonic sewing machine) No more thread, no more needle, no more glue When designing the Cera UltraSonic, our goal was to createa machine with the highest precision and performance in terms of continuous ultrasonic welding. The Cera UltraSonic ultrasonic rotary process allows to perfectly slide all types of fabric in order to get multiple patterns, cut and weld assembly and regular welding of 8 mm width, through a continuous processes.

Thanks to its large range of welding and cut-and-weld operations tools, the Cera UltraSonic gets even closer to your project requirements while being price-competitive and very simple touse. Dare our Cera UltraSonic and you’ll benefit from a 20 years proven rotary technology and from our worldwide expertise in designing production machines. http://www.cera-groupecera.com/en/standards/machines-to-weld-and-or-cut-by-sonics/ceraultrasonic-ultrasonic-sewing
