20Khz Ultrasonic Welding System for Beverage Cups And Lids Sealing Producing Line

Ultrasonic welding system  is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld. It is commonly used for plastics materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. RPS-WF20 Ultrasonic system consisted with ultrasonic generator, ultrasonic transducer ultrasonic horn, cylinder and frame, we have 3D model drawings, if any interesting, you can contact us to get the 3D model.

What's ultrasonic sealing?

All ultrasonic welding systems are composed of the same basic elements:

A press system usually with a pneumatic or electric drive, to assemble two parts under pressure

A nest or anvil or fixture where the parts are placed and allowing the high frequency vibration to be directed to the interfaces. This part not inclued in WF20 system.

An ultrasonic converter or piezoelectric transducer, an optional booster and a Horn. All three elements of the stack are specifically tuned to resonate at the same exact ultrasonic frequency (Typically 15, 20, 30, 35 or 40 kHz)

Booster: Modifies the amplitude of the vibration mechanically. It is also used in standard systems to clamp the stack in the press.

Horn: Takes the shape of the part, also modifies the amplitude mechanically and applies the mechanical vibration to the parts to be welded.

An ultrasonic generator (US: Power supply) delivering a high power electric signal with frequency matching the resonance frequency of the stack.

A controller controlling the movement of the press and the delivery of the ultrasonic energy.
