R&D focused organization manufacturing components made of advanced materials having applications in lasers and particle physics.

The customer is manufacturing very high value components (50 lakh to 2 crore rupees each)
The components have to undergo vacuum brazing.
Pre-cleaning of components is required
If components are not ultra clean before vacuum brazing, process failure is a high possibility
In case of process failure, the component cannot be salvaged. This is a high-risk situation demanding absolutely reliable and repeatable ultrasonic cleaning
Scientists at the firm decided to hire Ralsonics to build a multistage ultrasonic cleaning machines to perform the cleaning process
Ralsonics was chosen for this application considering our long-standing experience in developing specialized ultrasonic cleaning lines using an amalgamation of cleaning technologies.

Ralsonics designed a multistage ultrasonic cleaning system which provided both aqueous ultrasonic cleaning as well as flammable solvent based ultrasonic cleaning
Working hand in hand with customer scientists, Ralsonics developed a four-stage ultrasonic cleaning system.
The first stage included aqueous spray cleaning, cleaning with Ralsonics’ ultrasonic tube resonators and air agitation.
A pump filtration unit was provided to remove particle contamination
A separate storage tank with baffles and oil skimming facility was also provided for removal of soluble contamination like oil and grease
The second stage included a rotating basket with high pressure water rinsing facility to remove the cleaning chemical from the components
Ralsonics’ advanced multi-fluid spraying feature was provided for powerful spray rinsing
The third stage incorporated ultrasonic cleaning with tube resonators in IPA (flammable solvent). The equipment was designed to handle flammable solvents. Multiple advanced sensors were provided to ensure operator safety.
The fourth stage included hot air drying with HEPA filtered air. This ensured complete removal of all vapor traces

Customer specified cleaning standards were obtained with this ultrasonic cleaning line
Scientists at the customer site were very satisfied by the equipment
The versatility of the equipment ensured that it was used for cleaning of a wide variety of products in the facility

“You are using very high-end pumps! Most suppliers don’t provide this level of quality purchase parts”
