Product Description

20Khz wide frequency ultrasonic generator for ultrasonic machining



Power Supply. Every ultrasonic welder starts with a power supply. The power supply is sometimes referred to as the frequency generator because it takes standard electrical power (usually 115V) at 60 Hz and converts it to the operating frequency of approximately 20 kHz or 20,000 cycles per second. Other output frequencies commonly available range from 15-70 kHz. This high frequency current is then sent through a special cable to the ultrasonic stack.

Ultrasonic Stack. The stack is not one thing, but rather the combination of three core components: the converter, booster, and weld horn. In a plastic welder, the ultrasonic stack is aligned vertically and sits above the parts being welded in a supported column.

This digital generator is available in frequencies of 15kHz, 20Khz, 28Khz,30 kHz,  35 kHz and 40Khz at a power range between 300 W and 3000 W. Programmable ramp up and ramp down times and infinitely variable adjustment of weld amplitudes are only some of the features of this product line. The biggest advantage of this generator is the wide frenquncy range, for example: the 20Khz generator, it can catch the frequency from 18~21khz, so it is easy to tuning. Also it is easy for some ultrasonic new user.

100% digital control of all power supply functions and parameters allows for unique configurations and future upgrades or requirements. Includes digital frequency syntheses
Industry leading data acquisition rate speed of .5 ms due to advanced multi-core architecture. Increased weld accuracy and repeatability.



  1. Full digital control. Features user-friendly touch panel operation and superior integrated tracking function. Maintains ultrasonic output at a constant level regardless of power supply fluctuations or variation caused by addition or removal of cleaning targets. Details of malfunctions displayed as error codes.
  2. Compact, lightweight design. Both 300W and 3000W models have same dimensions. Stackable installation possible. (A maximum of four units can be stacked on top of each other.)
  3. Adjustable output range increased from 10 to 100%, allowing optimum output to best suit the target.
  4. Wealth of experience in surface treatment industry ensures excellent environmental durability. Everything, except ventilation channel, is sealed, providing superior durability even in harsh environments.
  5. Built-in timer gives advanced warning when vibrator lifetime approaches.
  6. Unique tracking function eliminates the need for bothersome tuning procedures when replacing vibrators, cutting down on time required for replacement work. Conventional electrostrictive vibrators can also be used.


1. DDS and PID high precision frequency control core.
2. Electric constant amplitude control system.
3. Welding amplitude setting range 0% - 100% by 1%.
4. Soft start, setting range 0-999MS, setprecison 1MS.
5. Three self-checking modes.
6. Pressure trigger/Time/Energy welding modes.
7. Six protections.
8. Less space, total weight 3.3KG.

Sonic & ultrasonic transducers are electro-mechanical or electro-acoustic converters. They transform electric energy into vibrations, which are used to generate mechanical, acoustic or even thermal power. Sonic transducers operate at audible frequencies, while ultrasounds operate at 20kHz or above. Transducers are often reciprocal devices: Most transducers can operate as sensors or generators exploiting mecano-electric conversion. This section introduces only actuation or emission modes. Conversion in such transducers is generally based on piezoelectric, magnetostrictive or magnetic forces.
The most conventional approach consists in using such forces to excite a mechanical resonance. For the same electric excitation, the vibration at resonance is the low frequency vibration multiplied by the mechanical Quality factor at resonance. This allows to achieve a good efficiency and reduced excitation voltages. The alternative way is to generate forced vibrations. Forced vibrations lead to large frequency bandwidth and are much less sensitive to load variations.
The usual ultrasonic transducers also called industrial ultrasonic processors are resonant structures typically based on 3 half-wave length resonators : a piezo converter, a booster and a sonotrode. They are used for ultrasonic welding, milling, cleaning, nebulization or ultrasonic assistance in drilling, extrusion, homogeneisation, filter declogging…HC-SONIC can define solutions using standard transducers. Customisation is often required to adapt the sonotrode to the load as shown below.
A new approach consists in using new active materials such as multilayer piezo ceramics (MLA) or giant magnetostrictive materials (GMM). These are used to build low frequency resonant transducers in dual-mass Tonpilz structures.
