In specific applications, fully automatic embossing machines mainly have mechanical effects (such as particle vibration displacement, velocity, acceleration, sound pressure, and other mechanical quantities of sound transmitting media), thermal effects (a part of the energy of sound waves is absorbed into thermal energy by the media during the propagation process), and cavity effects. In the past, complex mechanical parts required long-term manual cleaning in dirty environments, requiring a lot of manual labor. After the application of ultrasonic cleaning machine, it not only improves the working environment, eliminates the harm of manual cleaning to the workpiece, but also reduces labor intensity. On the basis of greatly improving cleaning accuracy, the cleaning time has been reduced to one quarter of the original.
Ultrasonic embossing machines, of course, do not all gas nuclei that appear in liquid management can develop a cavity effect. Only when the applied ultrasonic frequency is the same as the natural frequency of the gas nucleus, can cavity effect research continue to occur. At the same time, it is also influenced by other factors in society, such as the intensity of sound waves, temperature changes in liquid media, and the vapor pressure of different media. The appropriate frequency for inducing cavity effects is between 20kHz and 80kHz. Excessive frequency makes it difficult to control the cavity effect, and even if it is generated, a large amount of energy needs to be provided. Moreover, most of the energy in China is converted into thermal energy, which does not significantly increase the ambient temperature of the medium.
The application of low intensity ultrasound will not cause any changes in the state of the medium, and only the application of high intensity ultrasound can have a strong impact on the medium, causing cavity effects. For most chemical reactions, the reaction rate increases with the increase of "sound intensity". However, the impact of ultrasonic intensity is greatly influenced by the temperature of the medium.
