what's the characteristics of piezoelectric ceramic material Judging whether piezoelectric ceramic materials are suitable for surface acoustic wave devices can be considered in the following aspects: (1) The dielectric constant should be moderate. Generally, the dielectric constant is required

How to choose right ultrasonic transducerAn 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 proble

Common plastic variety identification method Polypropylene PP is easy to melt and drip, less yellow smoke on the yellow, continue to burn oil Polyethylene PE is easy to melt and drip, and yellow and blue continue to burn paraffin burning smell PVC is difficult to soften, yellow, green, smok

What is an ultrasonic horn (horn)We know that when an object vibrates, it makes a sound. Scientists refer to the number of vibrations per second as the frequency of the sound, and its unit is Hertz. The frequency of sound waves that we can hear in human ears is 20 to 20,000 Hz. When the vibration fr

Among the many products, plastic ultrasonic welding is used in many cases, and has been involved in automobiles, home appliances, packaging, toys, electronics and other commercial applications. Its unique advantages - fast, efficient, clean and firm, have won recognition from all walks of lifeFirst

Ultrasonic welding is normally divided into two modes: time mode and energy mode.Time mode of ultrasonic weldingThere are several control modes for welding equipment operation. The simplest and most common mode is the time mode, ie the ultrasonic energy acts for a predetermined time without regard t

Ultrasonic welding horns play 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•

1. Ultrasonic plastic welding machineWhen ultrasonic waves act on the thermoplastic plastic contact surface, high-frequency vibrations of tens of thousands of times per second are generated. This high-frequency vibration reaches a certain amplitude, and the ultrasonic energy is transmitted to the we

In the automotive industry, welding is a key link in the manufacture of automotive parts and bodywork. It plays a special role in connecting the upper and lower. At the same time, there are many models of automobile products, complex forming structures, specialized parts production, standardization,
