New process for capillary component geometries - MAFAC Vacuum Activated Purification (VAP)

"With MAFAC Vacuum Activated Purification (VAP), we have taken a further technological step towards being able to reach deep, capillary structures. It ensures improved media exchange in these critical cleaning geometries and thus improved dirt removal," explains Stefan Schaal, Technical Managing Director at MAFAC. For this purpose, the MAFAC VAP works with specifically introduced, controlled alternating pressures, which enhance the cleaning effect of the spray or spray-flood cleaning. The cleaning chamber is first evacuated with the items to be cleaned and then flooded to a predefined level. The cleaning medium penetrates into the blind holes and capillaries, where it dissolves the dirt particles present. In the next step, a controlled pressure change is generated in the cleaning chamber. The regularly changing pressure conditions cause an exchange of media as well as cavity effects, through which the dirt is cleaned effectively and gently.

Process for high-quality cleaning requirements

In combination with the patented MAFAC process technology of counter- or co-rotation of the basket holder and spray system, the new process achieves significantly improved particulate cleanliness for components with a capillary and complex structure. The process is very flexibly programmable and can be individually adapted to the respective requirements. MAFAC Vacuum Activated Purification is suitable for almost all applications, but particularly for medical technology, pharmaceuticals, optics, electrical engineering and the laser industry. Cleaning tasks on workpieces from 3D printing can also be fulfilled.
