What are the applications of ultrasonic cleaning machines in the electroplating industry

作者: Release Date: 2019-05-20 Author: Click:


At present, the electroplating profession does not know much about the practical application of the ultrasonic cleaning machine. The following will introduce the application of the ultrasonic cleaning machine in the electroplating profession by Juhe Ultrasonic. In electroplating, the purpose of the pretreatment is to allow dirt and impurities to exist on the surface of the workpiece, making it an active surface suitable for electroplating. Poor plating quality is often caused by poor pretreatment. However, the pretreatment is not good, and most of them do not use ultrasonic cleaning equipment.


When processing before electroplating, it is necessary to choose appropriate methods for useful cleaning according to the practice of the workpiece. Metal substrates are generally divided into stamped parts and die-cast parts. The oil stain on the stamping parts is general stamping oil, which is easier to clean because of its higher density. Generally available for pickling, electrolysis and so on. And zinc, aluminum, copper and other die castings are more difficult to clean due to the addition of various elements in the die casting. In addition, various oil products must be used in the process of forming, drawing, rolling, cutting, polishing , Polishing oil, etc. With regard to the ultrasonic cleaner, the oil can be easily removed. But polishing oil is divided into butter white oil, green oil, etc., which is more difficult to remove. Therefore, it is necessary to select a suitable ultrasonic cleaning equipment and cleaning solution.

在电镀行业超声波清洗机有着怎样的应用

The ultrasonic frequency is generally between 20-100KHZ. For pre-processing of common workpieces, low frequency and medium power ultrasonic cleaning equipment is generally used, such as frequency 25-28KHZ, power density 1W / cm.


Because low frequency is more likely to cause cavitation in the medium than high frequency, this type of washing machine can meet the requirements for workpieces with a simple shape and not very fine. It is characterized by high noise and low price. For some high-precision workpieces, high-frequency 40-68KHZ high-power ultrasonic cleaning machines are generally used. Therefore, such cleaning machines have better cleaning effects on workpieces with irregular appearance such as gaps, voids, deep holes, and blind holes. However, the effect of ultrasonic cleaning can only be achieved when the solution reaches the place. In other words, it is necessary to prevent air in the deep holes and blind holes, and pay attention to the phenomenon of foreign matter landing, oil staining, and inadequate cleaning.


Of course, the workpiece is rinsed after plating, but some more messy workpieces, especially those with gaps, deep holes, and blind holes (such as spectacle spring legs) cannot achieve the desired effect. Just use ultrasonic waves to remove the plating solution remaining in the gaps, deep holes and blind holes. Generally, you can choose an ultrasonic cleaner with a slightly higher frequency and a normal power density.
