The plating process is equipped with ultrasonic cleaning mainly based on the following reasons:
1. Efficient removal of surface contaminants
Ultrasonic wave through high-frequency vibration generated by the cavitation effect and mechanical vibration effect (such as eddy current, shear force), can quickly strip the parts surface oil, oxide layer, polishing paste and small particles of impurities.
Compared with the traditional acid cleaning or organic solvent cleaning, ultrasonic cleaning can avoid the chemical residue caused by secondary pollution or corrosion problems.
2. Enhance plating quality and performance
Clean surface can enhance the bonding of the plating layer with the substrate, reduce porosity, make the plating layer more uniform and dense, thus improving corrosion resistance, wear resistance and aesthetics.
Ultrasonic assisted chemical plating, but also refine the plating grain, improve the hardness and corrosion resistance.
3. Adaptation of complex structural parts cleaning
Ultrasonic waves can penetrate tiny gaps and holes, solving the pain point that traditional methods are difficult to clean complex shaped parts (such as threads, blind holes).
4. Environmental protection and process optimization
Replace the high pollution process (such as degreasing, strong acid descaling), reduce the use of harmful chemicals and improve the working environment.
Combined with intelligent control technology, the cleaning parameters (such as time, temperature, ultrasonic intensity) can be precisely adjusted to avoid damage to the plating layer or excessive cleaning.
5. Industry application and development trend
Ultrasonic cleaning has become a standard process for plating pretreatment in automotive, electronics, aerospace and other fields.
The future technology will develop in the direction of energy saving, intelligence and multi-technology integration to further improve the cleaning efficiency and environmental protection.
In summary, ultrasonic cleaning has become an indispensable part of the plating process through efficient decontamination, enhanced plating performance and environmental advantages.
