Ultrasonic welding transducer with rolling horn

Ultrasonic processing transducer stack is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials,embossing etc. In ultrasonic welding, there are no connective bolts,nails,soldering materials, or adhesives necessary to bind the materials together.

What we offer?

1, an ultrasonic stack composed of a converter or piezoelectric transducer, an optional booster and a sonotrode(US: horn). All three elements of the stack are specifically tuned to resonate at the same exact ultrasonic frequency( typically 20,30,35 or 40KHz)

     • Converter: converters the electrical signal into a mechanical vibration

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

     • Sonotrode: applies the mechanical vibration to the parts to be welded.

2, an electronic ultrasonic generator(US: power supply) delivering a high power AC sinal with frequency matching the resonance frequency of the stack.

The applications of ultrasonic welding are extensive and are found in many industries including electrical and computer,automotive and aerospace, medical and packaging. Whether two items can be ultrasonically welded is determined by their thickness. If they are too thick ,this process will not join them. This is the main obstacle in the welding of metals. However, wires,microcircuit connections,sheet metal,foils,ribbons and meshes are often joined using ultrasonic welding. Ultrasonic welding is a very popular technique for bonding thermoplastics. It is fast and easily automated with weld times ofter below one second and there is no ventilation system required to remove heat or exhaust.
