The ultrasound generator generates electrical vibrations with a frequence of 40,000 Hz per second. These vibrations are transferred to the material to be welded by a sonotrode.
The Ulta-Sonic technology with cold welding guarantees clean sealing and demonstrates numerous advantages:
-no heating time, the machine is immediately operational
-no odor and smoke build up
-no burnt film deposits
-no finger injuries due to heat
-no residues which can fall into the machine
-no replacing of heating elements
The sealing resistance can be set infinitely variable, lightly adhering so the seal can be opened by hand or up to the point of maximum sealing for heavy packages. This technology which works without damaging the edges of the product is appropriate for a variety of uses. Ultrasound is also successfully used for medical diagnoses.
