In forming technology, where large quantities of components – often collected in mesh boxes – need to be cleaned, vapor degreasers or hydrocarbon flood-washing systems offer a particularly efficient solution. These systems are specifically designed for batch cleaning of large and heavily soiled metal parts, as typically generated after punching, bending, or drawing processes.
The cleaning takes place in a closed system operated with hydrocarbon solvents. These solvents are highly effective against oils, greases, and drawing agents while remaining gentle on materials. After a pre-spray, which directs the majority of oils directly into the evaporator, a single flood-wash process is carried out. In the subsequent vapor degreasing process, solvent vapors rise from a heated bath and condense on the cooler component surfaces. The condensation dissolves the residues, which are carried away with the solvent. The solvent then fully evaporates, leaving the components dry and residue-free when removed from the system.
This method is particularly advantageous when cleaning entire mesh boxes, as it can handle large volumes in a short time and integrates well into automated production processes. Modern systems feature solvent recovery, explosion protection, and process monitoring to ensure both safety and environmental compliance. Continuous-flow systems allow very short cycle times while maintaining a separation between the dirty and clean areas of the system.
