Disadvantages:
Heated jaws apply heat on the outside of the tube to heat up the inside for sealing. This process is less efficient than High-Frequency Sealing. This method is for production of small to medium capacity.
Advantages:
The plastic inside the tube is heated and melted by high frequency friction force introduced from ultrasonic horn. Clamps closed and cooled and formed the melted plastic to seal the tube. This methos is suitable for production of small to medium capacity.
This system heats the seal area inside the tube by hot air. In a subsequent station, the tube is pressed and chilled. This methos is suitable for production of large capacity.
