Tube Sealing Systems

Imeco Ultrasonics manufactures tube sealing systems to seal laminated, co-extruded and plastic tubes. The ultrasonic tube sealing system comprises pneumatically actuated horizontally mounted welding head, complete with convertor, booster, special alloy horn and anvil. A generator is used to create an alternating voltage with an ultrasonic frequency of 20 or 40 kHz across a PZT crystal which converts it into mechanical vibrations. These vibrations are transmitted to a special alloy horn for sealing the plastic tubes. An exclusively designed shelf is provided to house generator, pneumatic controls and constant voltage transformer. Process details: on an assembly line, a filled tube with an open end entering the sealing stage activates a switch to start the sealing cycle. Pneumatic cylinders move the welding anvil and the ultrasonic horn to the tube. Then, with the application of ultrasonic vibrations for a preset interval, the open end of the tube is sealed.
