Plastic tubes are used in the cosmetic, consumer, medical, and food industries among others. Sealing of the tube end is required after product fill. Ultrasonic sealing technology is an excellent method of sealing the tube end.
The small footprint allows for easy integration in a lab setting. Unlike other tube sealing methods, ultrasonic tube sealing requires no hot tooling, no warm-up time, and no annoying teflon tape.
The tube sealer is controlled by a simple to use, compact touch screen controller. The controller can be table top mounted or tucked away under a shelf.
The actuator design also allows for integration in custom configurations or automation. Ultrasonic tube sealing systems allow for dramatically easier changeover when switching tube types during production than traditional hot air or thermal systems.
Advantages
Advantages of using ultrasonic sealing technology for tube sealing include:
- The ultrasonic sealing process disperses some types of product contamination in the seal zone thereby eliminating rejects.
- Fast seal time; typically 500ms to 3s depending on tube size.
- No warm up stage is required. The ultrasonic technology is exceptionally energy efficient.
- High seal pressure rating comparable to tube burst pressure.
- The ultrasonic sealing process is virtually silent.
- Tooling can include custom, changeable date/lot coding that is clearly embedded in seal zone during tube sealing.
- Sealing tubes with ultrasonics does not involve hot tooling or hot air. This makes ultrasonic sealing equipment ideal for sealing tubes filled with combustible product.
Special Designs
Great packaging design helps your product stand out to the consumer. Make your tubes attractive! Ultrasonic tube sealing can create a crown or wave seal. Sealing the tube end in a crown or wave pattern is often very difficult with alternative sealing methods such as hot air. Ultrasonic sealing technology allows manufacturers to make high quality crown and wave tube seals without headaches.
