It involves solvents in vapor form to cleanse the workpiece in preparation for further finishing operations.
The acting principle behind the vapor degreaser process is that the solvents will dissolve the contaminants on the workpiece and remove them by dripping off the part.
This contains the vaporized solvent in a closed space where the workpiece is placed.
With the impurities contained in the liquid beads, the solvent runs off the part.
Some systems are designed to capture and reclaim this solvent, making the process much more economical.
