ST 30

The demand for minimum inventory levels requires 'Justin time" (J.I.T.) manufac-turing techniques. Tube filling and sealing lines must be capable of quick changeover from laminates to high and low density plastic tubes and back with perfect quality and reliability. Ultrasonic tube sealing offers this capability with added benefits not available with other systems.

ST 30 - Tube sealer

Branson sealing systems are designed to be mounted as a station virtually all types of filling machines, whether in-line or rotary. require no warm-up time, since heat is actually applied to the being sealed.  Every tube goes through the prescribed weld cycle, so that stops and starts during the process will not produce heated or under heated tubes;this significantly reduces scrap. 

Since no other heaters or hot air streams are applied, the ultrasonic system is ideally suited for safely sealing tubes filled with low flash point materials such as products with a high alcohol content. The intense scrubbing action of the ultrasonic process disperses product to overflow such as stringers or splashes, which may occur during fill-ing. No other process has been so successful in eliminating this problem.

The Model ST-30 eliminates the need to stop and change tooling when changing from high to low density plastic tubes or laminates. A simple one-minute adjustment to the actuator permits sealing a variety of tube sizes and materials. Far less operating energy needed for ultra-sonic tube sealing than for other sealing methods. When the unit is operating at full power, 700watts are generated during the weld cycle, which is typically under one half second in duration. While the machine is “idling” (not actually welding a tube), the power draw is only about 10 watts.
