Vapor Degreasing for Precision Parts Cleaning

Vapor Degreasing for Metal Parts

Vapor degreasing is a process that is often used to remove oil and other solvent-soluble contaminants from a metal part. Vapor degreasing utilizes vaporized solvents to deep clean the entire surface structure of the part. The vapor degreasing formula consists of hot vapors of a chlorinated or fluorinated solvent to remove soils & particularly oils. The soils removed from the workpieces usually boil at much higher temperatures than the solvent, which results in the formation of essentially pure solvent vapors.

The Vapor Degreasing Process

The vapor degreasing process works by boiling a solvent to create a vapor which condenses on part surfaces into a liquid, dissolving soils which then drip away through the force of gravity. Solvent stability is usually controlled by the addition of stabilizers when the solvent is manufactured. Most common chlorinated solvents all require stabilizers to perform successfully within the vapor degreasing process.

Vapor degreasing machines are used for this process. They operate via an enclosed chamber that surrounds a heating element and a reservoir containing the necessary solvents. The process begins when a metal part is placed inside 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.

Vapor Degreasing Applications

The vapor degreasing parts cleaning process can be used for any type of workpiece and is utilized for a wide range of applications, including:

  • Thoroughly removing oil, 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
