20Khz Replace CJ20 Ultrasonic Welding Converter for Branson 2000 Series Plastic Welder

Description:

Ultrasonic Converters and Ultrasonic Transducers are one in the same. There is one Ultrasonic OEM, Dukane Corporation, that uses the term Transducer. All of the other ultrasonic OEM manufactures such as Branson, Sonics and Materials, Rinco, Telesonics and Herrmann refer to these as Converters or Konverters.

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.

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 transducer is an energy conversion device whose function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then pass it out, while it consumes a small amount of power (less than 10%). Therefore, the most important consideration for using ultrasonic transducers is the matching with the input and output terminals, followed by the mechanical mounting and mating dimensions. There are many types of ultrasonic machinery on the market, and customers must provide accurate and reliable indicators to ensure that the ultrasonic transducer products provided by the company can be matched with your company's ultrasonic machines to achieve the best performance.

Resonant frequency:

The frequency refers to a frequency measured by a transmission line method using a frequency generator, a millivoltmeter, or the like, or a frequency measured by an impedance analyzer or the like. Generally known as the small signal frequency. Opposite to it is the upper frequency, which is the actual operating frequency measured by the customer when the transducer is connected to the drive power supply via a cable and is unloaded or loaded. Because the customer's matching circuit is different, the same transducer with different driving power supply shows different frequencies, such frequency can not be used as the order basis.

The reasons why the transducer is often bad are:

1. The power loss of the transducer itself is large, and the transducer needs to consume a certain amount of power when vibrating. This loss power directly reflects the quality and process of the transducer, and the power consumed by the transducer itself is as small as possible. The greater the loss power, the greater the damage. In severe cases, the piezoelectric ceramic is directly broken. The amount of power loss directly reflects the process and quality of the transducer.

2. The aluminum alloy horn of the transducer is fatigue fracture (affected by the material life), and the amplitude is large.

3. The piezoelectric ceramic piece of the transducer is broken (by the piezoelectric ceramic itself, the mechanical strength causes loss and heat, overload and high power output, loose)
