Ultrasonic Cleaning Rubber - Case Studies
Ultrasonic cleaning is particularly effective for cleaning rubber components due to its ability to reach and remove contaminants from intricate and hard-to-reach areas. The high-frequency sound waves create microscopic bubbles that implode upon contact with surfaces, ensuring a thorough and efficient cleaning process. This method not only enhances the cleanliness of the rubber parts but also prolongs their lifespan by preventing the buildup of harmful residues. Additionally, ultrasonic cleaning is a gentle process that preserves the integrity and properties of the rubber, making it an ideal choice for maintaining high-quality standards in rubber component maintenance.
Process for cleaning Rubber:
The cleaning process began with the tank being heated to the required temperature and degassed. The component was then placed in a basket, submerged, and cleaned using ultrasonics for 5 minutes. Following this, the component was rinsed in tap water for 1 minute and subsequently dried in a hot air dryer set to 65°C for 5 minutes. Next, two larger components were cleaned together as a batch. These parts were loaded into the basket and underwent 5 minutes of ultrasonic cleaning. Upon inspection, some contamination was still present, so the parts were cleaned for an additional 5 minutes. The parts were then rinsed as before, for 1 minute in a static tap water tank, with gentle basket agitation to help remove any surface debris.
It is recommended to equip the necessary tank with both side and base-mounted transducers to ensure optimal cleaning results. Additionally, incorporating air bubble agitation in the rinse tank can further assist in removing any remaining surface debris, enhancing the overall efficiency of the cleaning process.

Process for cleaning Rubber:
Given the shape, size, and the multitude of parts needing cleaning, we utilised the basket rotation feature. However, the standard basket's spacing was too large for these parts, necessitating a lining with fine stainless steel mesh. Note: This setup is for testing purposes only; suitable baskets will be available for order. Loading The parts were meticulously loaded into the basket, and the lid was securely placed on top. Stage 1: Galvex 17.30N was selected for its compatibility with plastics and its superior emulsifying properties on machining oils and polishing compounds. Additionally, it boasts a long bath life. The basket, with the rotation feature activated, was immersed in the Galvex 17.30N solution for a total cycle time of 5 minutes. Stage 2: Following the cleaning stage, the parts were transferred to the tap water rinse tank to eliminate any soapy residue and remove any remaining debris. The tank’s auto purge feature ensured fresh water was added throughout the treatment, with excess water draining via the weir. The basket rotation feature was engaged for a cycle time of 2 minutes. Stage 3: Hot Air Drying Finally, the parts were dried in the hot air dryer set to 70°C, with the basket rotation feature turned on. Unloading The parts were then removed from the basket, showing no signs of contamination or water residue.
