mask-acting ultra sonic
Ultrasonic melting is used by the internal heating softening of the plastic by ultrasonic vibration.
In other words, it is a kind of heat welding that is welded with a non-adhesive agent.
The welding method involves direct welding and transfer welding, and the electron causes strong stress on the contact surface of HORN, which transmits ultrasonic energy, resulting in rapid thermal melting of the plastic. The latter is a phenomenon in which the ultrasonic energy transmitted to the plastic from HORN is subjected to severe collision on the opposite side of the plastic boundary, resulting in heat welding on the boundary surface.
composition of ultrasonic welder
Generator: electrical signal.
Vibrator: Convert electrical signals to mechanical vibration
main horn (Booster)
amplifying vibrations produced by oscillator
To compensate for the difference between the vibration amplitude generated by the vibrator and the practical amplitude that can weld the plastic, the main horn is used between the vibrator and the tool horn.
Tool Horn: Directly touching plastic to transmit vibration
Jig: The part that secures the weld.
Advantages of ultrasonic adhesion
It is efficient because the working environment is clean because no adhesive or solvents are used.
Instant glue time is effective in quality and productivity.
It is highly watertight and highly classified with strong adhesion.
Production efficiency doubles because no pre-treatment and post-treatment are required.
The difficult mold structure of the product can be easily solved.
Low power consumption and semi-permanent machine life require less maintenance.
Easy to use and uniform product quality and production efficiency are improved.
Automatic and semi-automatic batch work of the process is possible.
