30Khz High reliability Ultrasonic welding transducer for sealing

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.

Naming method:

T - Transducer
50 - The outside diameter for piezoceramic ring (mm)
20 - The frequency of the transducer
4 - The number for piezoceramic ring,
D - The type of transducer D means Chinese type,B-Branson type,Z-NTK type.
 
 
 
 
PARAMETER
 

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.
