Automobile Industry

The automobile industry is a mass production industry. Hence, what is critical is high throughput, repeatability and automation in any process used during manufacturing.


Ultrasonic cleaners are routinely utilized in the automobile industry to thoroughly clean various automobile components. Typically, the contaminants include dirt, carbon, oil, grease, metal shavings, lubricants and rust. Precision cleaning is required in this industry due to intricate parts being commonly manufactured.


Before ultrasonic cleaning was introduced, automobile industry cleaning involved operators cleaning components with brushes and toxic chemicals for days producing less than satisfactory results. Ultrasonic cleaning for the automobile industry saves on time as well as labor costs. The efficiency of cleaning is much better than manual cleaning (especially in hard to reach regions). Being an eco-friendly process, the usage of carcinogenic solvents for cleaning can be eliminated.


Ralsonics’ ultrasonic cleaners are well known in the industry to provide ultra-fast and thorough cleaning for automobile components ranging from fuel nozzles to engines. Ralsonics has a large range of products (multistage all-purpose cleaners, emission free vapor degreasers, ultrasonic cleaners), catering to every possible component that needs to be cleaned in the automobile industry.
