Customer
An R&D focused organisation manufacturing components made of advanced materials for applications in lasers and particle physics.
Problem
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 machine to perform the cleaning process
Ralsonics was chosen for this application, considering our long-standing experience in developing specialised ultrasonic cleaning lines using an amalgamation of cleaning technologies.
Ralsonics’ Solution
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 an oil skimming facility was also provided for the removal of soluble contamination like oil and grease
The second stage included a rotating basket with a 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 the complete removal of all vapour traces
Results
Customer-specified cleaning standards were obtained with this ultrasonic cleaning line
Scientists at the customer site were very satisfied with the equipment
The versatility of the equipment ensured that it was used for cleaning a wide variety of products in the facility
