A variety of seal patterns are available with date coding easily accomplished at the time of closure. Plastic tubes are used in the medical, consumer, cosmetic, and food industries among others. The ST-40 ultrasonic tube sealer is widely used in cosmetics and pharmaceutical industries. These sealers may be mounted as a station on virtually all types of filling machines, whether in-line or rotary. They require no warm-up time, since no heat is actually applied to the tube being sealed. This also means the ultrasonic system is ideally suited for safely sealing tubes filled with low flashpoint materials such as products with high alcohol content 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 ultrasonic tube sealing than for other sealing methods. When the unit is operating at full power, 1500 watts 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. accessories Branson offers a multitude of accessories for our metal welding systems including software for statistical process control and process validation.
