Ultrasonic Welding Working Principles |
| ★★★Ultrasonic Welding Working Principles★★★ |
Ultrasonic welding is a high technology of welding thermoplastic plastic products, and there is no need to add solvent、adhesives or other aids. Its advantages: increasing production, decreasing the cost and improving the products quality and safely producing.
Ultrasonic plastic- welding working principles: high pressure and high-frequency signal generated by generators, converts signal to high frequency mechanical vibration, adds to the plastic workpieces, then through the surface and inner parts of friction, the interface temperature will rise, when the temperature reaches the melting point of this piece itself, the workpieces interface will melt rapidly, and then fill in the gap between the interface, when the vibration stops, the workpieces while cooling under pressure in certain amorphous, they achieve perfect welding.

Stable frequency
According to the rules of CISPR, we adopt the industrial band 27.12/40.68MHZ and design the frequency stabilizer and magnetic leakage suppressor, so that can lower to interference the external devices largely.
Strong output
It adopts low-loss coaxial oscillator, the output waveform good, high quality factor, contribute to an exceptionally strong, fast welding.
Unique and novel design
Local novelty, height adjustable head. Promote the use of cylinder pressure evenly on and off the smooth, circuit programmable time control systems, time parameters preset, can accurately complete the warm-up, welding, all cooling operation, electromagnetic and can count.
Oscillation current stop set
The machine output power can be easily adjusted with the adjuster, according to the size and thickness to set the desired oscillation current to control the degree of welding, weld quality to ensure product uniformity.
Spark suppression
The machine has high sensitivity spark suppression circuit, spark detected accurately the current imbalance, quickly cut off in an instant spark oscillation circuit, spark suppression, so that the mold, raw materials and products to minimize the damage.
Security protection
The machine has over-voltage, over-current protection device, the work can be automatically cut off when an exception to protect oscillation tubes and high voltage rectifiers, while avoiding the frequency drift caused by improper operation.
