11 - 12nf Capacitance Ultrasonic High Power Transducer 20Khz 2000w Branson 803

High Power Ultrasonic Replacement Transducer 20Khz 2000w Branson 803

Description:

Replacement converter for Branson 803 Converter . For use with 187p power supply (with the 801 actuator) and the model 8700 press. The converter is threaded onto a booster, which increases, decreases or just transfers the amount of movement from the face of the converter to the horn or Sonotrode as we call it.

Ultrasonic Converters and Ultrasonic Transducers are one in the same. Converters or Transducers all do the same thing…convert electrical energy to mechanical movement…so we have our electrical charge being introduced across the surface of the ceramics at the desired frequency which in turn gives us a movement or vibration at the working end on the converter.

Ultrasonic plastic welding water, gas-tight fuse line (weld wire) design:

When we want the product to achieve the function of water and airtightness, positioning and ultrasonic melting line are the key to success or failure. Therefore, in the design of the product, such as: positioning, material, flesh thickness, and the corresponding ratio of the ultrasonic melting line Absolute relationship. In general water and airtight requirements, the height of the fuse line should be in the range of 0.5~0.8m/m (depending on the thickness of the product), such as below 0.5m/m, to achieve the function of watertightness, unless The positioning setting is very standard, and the thickness of the meat is 5 m/m or more, otherwise the effect is not good. The way in which water-tight products are generally required to be positioned with the ultrasonic waveguide fuse is as follows:
It is suitable for watertightness and fusion of large products. The contact angle is 45°, x=w/2, and d=0.3~0.8mm.
Stepped tip type: Suitable for watertightness and prevention of protrusion or cracking. The angle of the contact surface is 45°, x=w/2, and d=0.3~0.8mm.
Peak-to-valley: suitable for watertight and high-strength welding, d=0.3~0.6mm The height of the inner contact surface h varies depending on the shape, but h is about 1~2mm.
Ultrasonic operation of the product can not achieve water and airtightness. In addition to the factors such as ultrasonic melting line, fixture positioning, and product positioning, the conditions for ultrasonic setting are also a major cause. Here we delve deeper into another reason (smelting conditions) that ignite water and airtightness. When we implement ultrasonic welding, it is the most basic goal to seek efficiency, but it often ignores the essentials of efficiency. There are two phenomena:
First, the descending speed, buffering too fast: the speed of this formation, so that the dynamic pressure plus gravity acceleration will flatten the ultrasonic fuse line, so that the fuse line can not play the role of melting, forming a pseudo-phase welding.
Second, the welding time is too long: plastic products received by the long-term thermal energy, not only the plastic material melted, but also caused the plastic tissue coking phenomenon, the production of sand holes, water or gas that penetrates the sand hole. This is the most difficult place for general production technology to discover.
