Ultrasonic transducer principle and ultrasonic mold matching 1. Ultrasonic transducer principle and design (ultrasonic vibration system) matchingAbstract: The design and calculation of the ultrasonic transducer system of plastic welding machine, and the use of PRO-E three-dimensional software to dra

Ultrasonic welding is unevenly stressed and weldedWhen the ultrasonic works, the contact between the product and the surface of the mold can get the desired welding effect. In fact, this is only the surface view. Since the ultrasonic vibration is frictional vibration, the sound wave transmission phe

Frequency has nothing to do with amplitude.The number of full vibrations completed by the vibrating mass in one second is called the frequency of the vibration, and its unit is Hertz (Hz). The frequency is also the physical quantity indicating how fast the particle vibrates. The higher the frequency

The amplitude is a key parameter for the material to be welded, which is equivalent to the temperature of ferrochrome. If the temperature is too low, it will not be welded. If the temperature is too high, the raw material will burn or cause structural damage and strength. Because each transducer is

Piezoelectric ceramic sheet quality is the main factor determining the life of the transducer. The transducer is cracked during assembly, and the piezoelectric ceramic itself has problems, such as internal delamination, and the mechanical part of the vibrator is too far from the expected value. The

The ultrasonic welding process of the product needs to meet three basic conditions to achieve the desired effect.1. Whether the two plastic materials can be welded: Some materials can be welded better, some are basically melted, and some are not melted. The melting point between the same material is

Ultrasonic probe ultrasonic flaw detection principle and sensor test and designUltrasonic transducers, horn and vocal sleeves are devices that convert electrical energy into vibration. To understand the principle of operation, a comparison can be made between an ultrasonic welder and a car.The

At present, the advantages and disadvantages of the welding process play a decisive role in the heat transfer of the flat-plate solar collector, while the domestic flat-panel solar water heater collector (heat collecting plate) is mainly welded with laser welding and ultrasonic welding, and the flat

The secret of ultrasonic welding is to focus the ultrasound with the energy director. In this way, heat can be generated and then melted with only a small amount of energy, limited to locally defined regions. Large areas of contact surfaces are counterproductive; they require high power and only ach

The welding horn plays a key role in ultrasonic welding. But what kind of "tool" is the welding horn, and what is its role? Let us introduce them one by one.The horn is a tool that effectively transmits vibration to the plastic weld. It has the following features:· Transfer vibration energy· Passi
