Raetts - Model RT-V-5.0 / RT-20K-ATS -Intelligent Ultrasonic Generator

Ultrasonic welding principle:

Ultrasonic action on the thermoplastic contact surface, will produce tens of thousands of times per second of high-frequency vibration. This to achieve a certain amplitude of high-frequency vibration, through the upper welding piece to transmit ultrasonic energy to the welding area. Because the welding area is the interface of the two welding sound resistance, it will produce local high temperature.

Also due to poor thermal conductivity of plastic, the temperature could be released in time, and will be gathered in the welding area. This results in the rapid melting of the contact surface of the two plastics, plus a certain amount of pressure, so that it is integrated into one. When the ultrasonic wave stops, let the pressure last a few seconds, it solidifies to form a strong molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of the raw material.

The quality of ultrasonic plastic welding depends on the amplitude of the transducer welding head, the added pressure and welding time these three factors. welding time and welding head pressure can be adjusted, amplitude by the transducer and the amplitude. pole decision. These three quantities of interaction have a suitable value, energy exceeds the appropriate value, the melting amount of plastic is large, the weld is easy to deform; This optimal pressure is the optimal pressure build-up for the edge length of the welded section and the edge per 1mm.

RAETTS RT-V-5.0 Generator Features

1. high stability: full digital integrated circuits, adopts the United States imported high-performance anti-jamming processor. Reduces the number of components, simplify the hardware structure. Increases the stability of the function to improve the reliability and stability of the system.
2. frequency automatic tracking: digital frequency synthesis technology combined with digital phase lock ring frequency tracking composite control technology, can eliminate temperature, static load, processing area, tool wear and other factors drift conventional analog regulator difficult to overcome the shortcomings. It is conducive to parameter adjustment, easy to adjust control programs through the modification of program software, easy to adjust the control plan and implement a variety of new control strategies.
3. strong force: the use of IGBT power module coupled with his exciting shock circuit structure, makes the output power is more than 1.5 times the traditional self-exciting circuit.
4. amplitude non-polar adjustment: amplitude can be in the adjustment process instantly increase or decrease. It can also be fine-tuned. This will effectively prevent the size of the adhesive can be perfect welding, effectively reduce the puncture, burns and so on. The setting range of the negative amplitude is 10% to 100%.
5. intelligent protection and fault alarm tips: There is mold current overload protection, frequency offset protection and the total output overload protection. When the equipment fails, the generator stops working immediately. And will indicate relevant malfunction tips until the technician corrects the problem.
6. intelligent closed loop amplitude control technology: It can achieve amplitude size adjustment, not affected by the impact of the input supply voltage and load fluctuations. Then it will maintain a constant amplitude output.
