Components :
All ultrasonic welding systems are composed of the same basic elements:
A press to put the two parts to be assembled under pressure
A nest or anvil where the parts are placed and allowing the high
frequency vibration to be directed to the interfaces
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 40
kHz)Converter: Converts the electrical signal into a mechanical
vibrationBooster: 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.
An electronic ultrasonic generator (US: Power supply) delivering a
high power AC 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.

Description:
Ultrasonic transducer is a component that utilize the piezoelectricity for actualize electroacoustic conversion. jydsonic ultrasonic cleaning transducer are used where powerful ultrasonic wave must be generated, such as in cleaning equipment and easy to instal. These transducers are mounted into a structure that can be bolted almost anywhere.
• 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.
Ultrasonic transducer is the core device that converts electrical energy into mechanical energy (ultrasonic), the piezoelectric ceramic chip adopts imported parts, and can give a strong and stable output. It is made from American aluminum alloy and titanium alloy. The frequency is 15 KHZ ~ 28 KHZ.
Product feature:
1. The piezoelectric ceramic chip adopts imported parts, and can
give a strong and stable output.
2. High efficiency, high mechanical quality factor, obtaining high
electric-acoustic conversion efficiency work at the resonance
frequency points.
3. Large amplitude: optimization design by computer , vibration
speed ratio is high .
4. Large power,Under the action of prestressed screw, the energy of
the piezoelectric ceramic to get maximum play;
5. Good heat resistance, small harmonic impedance, low calorific
value, using temperature range is wide.
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 often below one second and there is no
ventilation system required to remove heat or exhaust.
