Vacuum impregnation equipment includes dry and wet vacuums used to prepare the impregnation resin. The absence of liquid within the dry vacuum method ensures no interference with degassing the pores. Within the wet vacuum method, penetration of the impregnation resin into the part takes place at atmospheric pressure, enabling rapid processing. Once prepared, the impregnation resin fills porosities, shrinkage cavities, capillary pores and cracks to ensure resistance to external influences.
