Engineering industry

The engineering industry is a very diverse industry serving thousands of applications ranging from consumer goods to support for other sectors. The primary use of ultrasonic cleaning in this industry is to ensure a consistent and repeatable cleaning process. The engineering industry requires dependable and long lasting machinery.


Typically the engineering industry requires cleaning of machined parts in removal of any contamination, especially in hard to reach areas of components. Furthermore, before finishing processes like plating, anodizing, coating etc. pre-cleaning with ultrasonics ensures much better adherance of the coating layer leading to longer life. Mold cleaning is another common application in this industry for regular cleaning of mold release and opening blocked exhaust vents.


Ralsonics’ ultrasonic cleaners are well known in the industry to provide ultra-fast and thorough cleaning for engineering components ranging from screws 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 engineering industry.
