Can Ultrasonic Cleaners Clean Plastic Products?

Customers often ask if ultrasonic cleaners can be used to clean plastic products. If possible, will cleaning cause damage to the workpiece or the washer? In fact, the question is simple, and here is a simple answer.

The effect of ultrasonic cleaning is related to the elastic modulus of the material. Different materials have different high-frequency mechanical vibration energy absorption amplitudes, foreign matter is peeled off, the plastic elastic modulus is much smaller than that of metal, and the ultrasonic absorption is stronger.

Due to the relatively soft texture of plastic, which is very different from stainless steel, and the corrosion resistance of plastic materials being more similar, it can no longer be cleaned in corrosive liquids. "In fact, we should be able to understand that the high-frequency mechanical vibration energy absorbed by different materials is very different, and the plastic strength is much lower than that of metal materials, so in the case of ultrasonic cleaning, different materials absorb high-frequency mechanical vibration energy. A big difference is that plastic strength is much less than the strength of metal materials, so in the case of ultrasonic cleaning, can you resist the effect of ultrasonic waves?

After testing by our professional engineers, the ultrasonic cleaning machine can clean ordinary plastics without damaging the cleaning machine and plastic products. It should be noted that the cleaning temperature of the cleaning solution is around 50°C. The colder the weather, the lower the temperature of our cleaning fluid, the worse the cavitation effect, the poor cleaning effect, the need for heating, and the temperature of the cleaning fluid will increase.

Therefore, when we use ultrasonic cleaning equipment for cleaning, we should learn to control the temperature of the ultrasonic cleaning machine according to different materials. If the control is not good, it may cause irreversible damage to the workpiece.
