Features :
-
Sound Wave Frequency and Principle: Ultrasonic waves, beyond the range of human hearing, utilize high-frequency vibrations to fuse materials. A transducer converts electronic energy into mechanical vibration, operating at frequencies between 18,000 and 35,000 cycles/second.
-
Welding Mechanism: Ultrasonic welding generates 35,000 high-speed heat frictions per second between materials (plastic-to-plastic or plastic-to-metal) to create a strong bond.
-
Welding Methods:
- Direct Welding: Materials overlap and are fixed on the welding machine's fixture, where sound wave vibrations directly fuse them.
- Conduction Welding: Ultrasonic vibration is separated from the welding surface, using sound wave vibrations to create the weld.
-
Material Compatibility:
- Suitable for most thermoplastics, except Teflon.
- Performance varies with plastic properties, such as friction coefficient, thermal conductivity, and hardness.
- Hard plastics weld efficiently due to minimal vibration loss.
- Crystalline plastics require precise adjustments due to their narrow melting range.
- Soft plastics perform better during riveting or insertion.
Advantages :
- Short welding times (0.05-1 second).
- Enables airtight and liquid-tight seals.
- Supports welding through media like water or oil.
- Minimal surface damage, ensuring a clean finish.
- Safe and non-toxic, eliminating chemical agents.
- Simple, adhesive-free operation.
