Laser Cleaning VS Ultrasonic Cleaning
Ultrasonic cleaning is the use of ultrasonic generator issued by the cross-frequency signal, through the transducer, which is converted into a cross-frequency mechanical oscillation and spread to the medium, that is, "bubbles" in the cleaning fluid , result in the rupture phenomenon. When the "cavitation" reaches the surface of the object to be washed at the moment of rupture, it generates an impact of well over 1000 atmospheric pressure, causing the dirt in the surface, holes and gaps of the object to be dispersed, ruptured and flaked off, so that the object can be purified and cleaned.
Laser cleaning technology is the use of a high-energy laser beam to irradiate the surface of a workpiece, causing instantaneous evaporation or stripping of dirt, rust spots or coatings. It achieves cleanliness by effectively removing adherents or coatings from the surface of the object at high speed. It is a new technology based on the interaction effect between laser and matter.
The difference between laser cleaning and ultrasonic cleaning is that laser cleaning operation is very convenient, general hand-held cleaning can be done. Without any medium, can directly clean on the surface of the object. For large area cleaning and precision parts cleaning，the effect is great, and the working temperature is -5℃~50℃. While for the ultrasonic, additional cleaning agent is needed, it handles small workpieces only , and can not remove the coating layer or sub-micron particles. The higher the power density of ultrasonic, the stronger the cavitation effect, the faster the speed, the better the cleaning effect. However, for precision objects with a high surface finish, the use of long periods of high power density cleaning will produce cavitation and corrosion on the surface of the object.
Laser cleaning features.
1, non-abrasive, non-contact cleaning, avoiding secondary pollution.
2, high cleaning accuracy and controllability.
3, no consumables, environment friendly.
4, laser cleaning can remove different types and thickness of adhesions on the surface of various materials.
5, easy to manipulate, handheld or with the robot to achieve automated cleaning.
6, high cleaning efficiency, saving time.
7, stable system, long service life.
8, one-time investment, economic and efficient.
Modern high-end manufacturing cleaning areas such as aerospace, rail transportation, automotive manufacturing and mold industry, there are long-standing cleaning difficulties, high precision requirements, slow efficiency and other pain points, the market demand has also given rise to a higher industry requirements of the laser cleaning industry.
For example, the quality of the mould directly affects the quality of the tyre. It is vitally important to keep the tyre mould clean as with carved patterns or other patterns, the mould will often be used in high temperature, high humidity environment, so there will be a lot of rubber or other residues left in the carved groove, when accumulated to a certain extent, it will affect the shape of the mould structure and eventually lead to the production of defective products.
The traditional cleaning process has the use of ultrasonic cleaning machines. Ultrasonic cleaning can have a negative impact on the production of moulds as the process is time-consuming and some moulds need to be dismantled during cleaning. In addition, this process can only be used for moulds that have been cooled. Only after the mold is cooled, cleaned and reheated can a new round of production be restarted, which is time-consuming and labor-consuming. Laser cleaning of moulds mainly uses the principle of laser cleaning to remove the dirt on the mould surface and the residues from the production, which is a physical cleaning, efficient, environmentally friendly and pollution-free, with good cleaning effect. The traditional cleaning process cleans moulds in a variety of ways: sandblasting, dry ice, grinding, chemical scrubbing, etc. When the cleaning environment is poor, it may cause unnecessary damage. Replacing the original ultrasonic cleaning with laser cleaning reduces the cost of use by more than 50% and significantly improves the overall product qualification rate.
Laser cleaning has obvious advantages compared to traditional cleaning methods such as ultrasonic cleaning and chemical etching cleaning: it is efficient, fast, low cost, produces little thermal and mechanical load on the substrate, and the cleaning is non-damaging; does not damage the health of the operator; cleaning process is easy to achieve automatic control, to achieve remote control of cleaning over long distances, etc. MRJ-Laser focuses on personalized and intelligent laser marking, laser cleaning, laser welding customized R&D; It has been widely used in various industrial manufacturing fields such as aerospace, rail transportation, automobile manufacturing, precision machinery, electronics and electrical appliances, jewelry, craft gifts, etc. It has been sold to more than 60 countries and regions worldwide such as the United States, Germany, Italy, India, South Africa, Japan, Canada, etc.Now more attentions are paid to environmental protection, many traditional cleaning processes are gradually being replaced, laser cleaning is becoming the mainstream of industrial cleaning, the future is promising!
