Advantages of laser cleaning over ultrasonic cleaning

Ultrasonic cleaning is to use the AC frequency signal sent by the ultrasonic generator, which is converted into the mechanical oscillation of the AC frequency by the transducer and propagated to the medium, that is, in the form of “bubbles” in the cleaning liquid, which is generated and ruptured. When the “cavitation” reaches the moment when the surface of the object to be washed breaks, it will generate an impact force far exceeding 1,000 atmospheres, which will disperse, crack and peel off the dirt on the surface of the object, the dirt in the pores and the crevices, so that the object can be purified. and clean.

Laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, rust spots or coatings on the surface of the workpiece are instantly evaporated or peeled off, and the surface attachments or surface coatings of the objects to be cleaned are effectively removed. High speed, thus enabling the cleaning process. It is a new technology based on the interaction of laser light with matter.

The difference between laser cleaning and ultrasonic cleaning is that laser cleaning is very easy to operate. In general, hand-held cleaning is possible. The surface of the object can be cleaned directly without any medium. It has a good effect on large area cleaning and precision parts cleaning. The working temperature is -5°C to 50°C. The ultrasonic wave needs to be added with a cleaning agent, which can clean small workpieces, but cannot remove coatings and sub-micron particles. The higher the power density of the ultrasonic wave, the stronger the cavitation effect, the faster the speed, and the better the cleaning effect. However, for precision objects with very high surface finish, long-term high power density cleaning can cause cavitation and corrosion on the surface of the object.

The cleaning fields of modern high-end manufacturing industries such as aerospace, rail transit, automobile manufacturing, and mold industry have long been faced with pain points such as difficult cleaning, high precision requirements, and slow work efficiency. Market demand has also spawned a higher level of laser cleaning industry. Industry requirements.

Advantages of laser cleaning over ultrasonic cleaning

For example, the quality of the mold directly affects the quality of the tire. There will be engraved patterns or other patterns on the surface of the tire mold, and the mold is often used in a high temperature and high humidity environment, so a lot of rubber or other residues will be left in the engraved grooves. To a certain extent, it will affect the shape and structure of the mold, and eventually lead to defective products, so it is particularly important to keep the tire mold clean.

The traditional cleaning process involves the use of ultrasonic cleaners. Ultrasonic cleaning can negatively impact mold production because the process is time-consuming and some molds need to be disassembled during cleaning. In addition, the process can only be used to cool the mold. A new round of production can only be restarted after the mold is cooled, cleaned and reheated, which is time-consuming and labor-intensive. Laser cleaning molds mainly uses the principle of laser cleaning to remove the dirt on the surface of the mold and the residues in the production process. It belongs to physical cleaning, which is efficient, environmentally friendly, non-polluting, and has good cleaning effect; the traditional cleaning process is diversified in cleaning methods: sandblasting, dry ice, grinding, chemical scrubbing, etc. The cleaning environment is not good and may cause unnecessary damage. Replacing the original ultrasonic cleaning with laser cleaning can reduce the cost of use by more than 50%, which can greatly improve the overall qualification rate of the product.

Compared with traditional cleaning methods such as ultrasonic cleaning and chemical etching cleaning, laser cleaning has obvious advantages: high efficiency, rapidity, low cost, low thermal and mechanical load on the substrate, no damage to cleaning; it will not damage the operator. Healthy; the cleaning process is easy to realize automatic control, realize remote remote cleaning, etc. Jiabang Laser specializes in laser cleaning business.
