Vapor Degreasing for Precision Parts Cleaning
What is Vapor Degreasing?
Vapor degreasing is a surface finishing process that uses vaporized solvents to remove oil and other solvent-soluble contaminants. A number of solvents can be used in vapor degreasing, depending on the material(s) from which the workpiece is made and the nature of the contaminants present. Arrow Cryogenics expertise in vapor degreasing and cleaning enables us to determine the ideal cleaning process for each customers unique application.
How Does Vapor Degreasing Work?
A vapor degreaser is a machine with an enclosed chamber surrounding a heating element and a reservoir containing the necessary solvents. The workpiece is placed into the chamber, and the heating element is used to bring the solvent to a boil. As the solvent boils and evaporates, the resulting vapors rise into the open space within the chamber.
The workpiece, being cooler than the solvent vapors, causes the vapors to condense on its surface. As the vapors condense back into liquid form, they penetrate the contaminants and contain them within their now-liquid structure. The solvent is left to drip off the part, taking the impurities with it.
This precision part cleaning process lends itself to a wide variety of applications, as workpieces of any shape can be cleaned through this process.
Vapor degreasing is ideal for:
- Thoroughly removing oil, grease, and other solvent-soluble contaminants
- Penetrating blind holes, cracks, recesses, etc. for perfect precision parts cleaning
- Preparing part surfaces for finishing processes such as painting and welding
- Cleaning electronics parts and components that may be damaged by cleaning with water
- Cleaning inserts prior to being molded into material
