Ultrasonic Cleaning Technology: An Efficient Method for Mold Cleaning


In the rubber industry, there are various methods for cleaning rubber dirt inside molds, including steam flushing, chemical solution soaking, manual grinding, and ultrasonic cleaning. Among these, ultrasonic cleaning outperforms other methods, serving as an efficient and innovative cleaning solution.

Principles of Ultrasonic Cleaning

Ultrasonic cleaning is a wet cleaning method that utilizes high-frequency vibrations (typically above 20kHz) to generate tiny bubbles in the cleaning fluid. When these bubbles burst instantaneously, they produce powerful impact forces, known as the "cavitation effect." Along with mechanical efficiency and acceleration effects, this thoroughly cleans dirt on the surface and inside of molds. Furthermore, ultrasonic cleaning does not cause damage to molds while achieving complete removal of impurities and dirt.

Specific Application Examples of Ultrasonic Cleaning in Rubber Processing Molds

Surface Cleaning of Rubber Molds

For dirt such as oil stains and rubber residues on the surface of rubber molds, ultrasonic cleaning can quickly and effectively remove them, maintaining the cleanliness of the mold surface.

Internal Cleaning of Rubber Molds

Targeting the intricate internal structures and hard-to-reach areas of molds, ultrasonic cleaning can penetrate deep into these regions for thorough cleaning, ensuring the internal cleanliness of the molds.

Cleaning of High-Precision Molds

For high-precision molds that cannot tolerate even the slightest damage, ultrasonic cleaning can complete the cleaning work without damaging the mold surface, meeting the cleaning requirements of high-precision molds.

Cleaning Equipment Design

In view of the characteristics of mold cleaning, ultrasonic devices differ from conventional ultrasonic cleaning devices. Instead of installing the generator at the bottom of the cleaning tank, it is mounted on the side of the tank. This design offers two advantages: first, it simplifies the installation process during mold cleaning, and the ultrasonic generator will not be contaminated by impurities deposited at the bottom of the tank; second, the tank bottom can function as an impurity collector, thereby extending the service life of the cleaning fluid.
 
Compared with other cleaning methods, ultrasonic cleaning reduces labor intensity, saves cleaning time, and avoids mold damage (especially crucial for high-precision molds that cannot tolerate even minor damage). Ultrasonic cleaning of molds is one of the most effective methods among various chemical, physical, and mechanical cleaning techniques.
