Choosing Between Ultrasonic Sealing Tube Machine And Heat Sealing Tube Machine 2021-12-16
Ultrasonic sealing is a modern technology that employs the use of sound–mediated vibrations to release heat at a molecular phase inside the tube itself. These vibrations, generated from an anvil and sonotrode, agitate the molecules in the plastics so that they flow. Once the plastic becomes soft and starts melting, its parts are connected by a strong cohesive force to form perfectly-fit joints. After a short time of cooling under pressure, they form firmly joined molecules. This friction at the molecular level helps in the sealing of the product without the use of direct heat.
