Ultrasonic Welding System for Surgical Mask N95 Ear Loop Welding 20khz 2000w
What is an ultrasonic welder? Ultrasonic welding (USW) is a solid-state welding process that produces a weld by local application of high-frequency vibratory energy while the work pieces are held together under pressure. 5. A sound metallurgical bond is produced without melting the base material. How does ultrasonic welding machine work? The vibrations, produced by a welding sonotrode or horn, as it is generally known, are used to soften or melt the thermoplastic material at the joint line. The components to be joined are held together under pressure and subjected to vibrations, usually at a frequency of 20 or 40 kHz. Where is ultrasonic welding used? Ultrasonic welding is used in almost all major industries like automotive, electronic and appliances, medical, packaging etc. A limitation of ultrasonic welding is that with current technology, large joints cannot be welded in a single operation. In addition, specifically designed joint details are required.

Features:
Automatic frequency tracking: The system automatically tracks the resonance frequency of the welding horn. Compensate for detuning caused by heat and other reasons.
Digital frequency control: The operating frequency is digitally controlled by the microcontroller.
Digital amplitude setting: This feature allows users to set precise amplitudes according to application requirements, which provides a larger range and repeatability of settings than analog systems.
The amplitude can be adjusted in a large range: 1% ~ 100% continuously adjustable, which is different from the shortcomings of traditional generators that are difficult to work with low amplitude.
High-speed micro-controller: The internal micro-controller operates at a frequency of up to 168MHz, which can accurately and timely control the working conditions.
Control and sampling interval of 0.5 milliseconds: 2000 times of sampling and control for welding process per second.
Color touch screen display: Through the color screen and touch, friendly and easy-to-use human-computer interaction is realized, and the experience is better.
Coexistence of buttons and touch: common functions can provide better interaction through buttons. Among them, the buttons use silicone keys, which have a better feel.
Operating language: The user can select the applicable language in the start screen: currently only supports English and Chinese.
Slant start: Ultrasonic energy supply and welding horn start at the most suitable ascent speed to reduce the electromechanical pressure of the system.
Vibration after welding: The user can start the ultrasonic after the welding and pressure holding process is finished, and the workpiece sticking to the welding horn will be shaken off.
Welding quality monitoring: user-definable process alarm. When it is outside the range of user-defined defective products, the system will generate an alarm to remind .
