Compact welding cabin with exchangeable tool cassette

The iSONIC ECOFLEX ultrasonic welding cabin presents itself in a completely revised concept. The special feature is above all the working area: Individually tailored to the respective application, it is now integrated into the cabin as an exchangeable tool cassette. The cassette can be exchanged either from the operator side or from the rear of the machine.

The tool cassette has a modular structure and is equipped with 20, 30 or 35 kHz ultrasonic technology for surface, piercing and rivet type joints. Also, small punching applications can be implemented. For this, SONOTRONIC uses its own highly developed ultrasonic components. All ultrasonic components as well as the parts nests are developed and produced in our own production facilities based on the workpiece CAD data. Likewise, programming of the PLC control and remote maintenance is performed directly in-house.

100% modular and powerful - ideal for small to medium size components

The iSONIC ECOFLEX enables changing over of the working area, which is fitted by default as a tool cassette, from either the front or rear side. This means that multiple workpieces can be processed in individual working areas on one and the same machine. Alongside storage space in production, this is a primary saver of investment costs. With a tool change trolley and smooth-running ball bearings in the machine interior, the tool cassette can be changed quickly and ergonomically. The insertion or removal of the tool cassette can be performed via both the operating and rear side. To do so, both sides have wide opening areas, which is also helpful for maintenance.

The iSONIC ECOFLEX welding cabin is particularly economical for the production of small and medium-sized components. It is ideal as a "filling workstation" for non-just-in-sequence production or perfect as a supplement to large systems (e.g. center consoles, instrument panels or door panels) for small assemblies installed there, such as tweeters, interior door actuators, decor panels, storage compartments or cup holders.
