Abstract
A machine for impregnating a die cast metal part with liquid impregnant comprises an impregnation chamber having liquid impregnant in a lower portion, an opening for ingress and egress of the parts being defined in a side wall of the chamber above the liquid impregnant, a door for sealing the opening, a part holder in the chamber and an elevator for positioning parts above the liquid impregnant during evacuation of the chamber and then immersing the parts in the liquid impregnant during subsequent pressurization of the chamber.
Claims8
A process for impregnating a die cast metal part in an impregnation chamber having liquid impregnant in a lower portion thereof, the process comprising,
- loading the part into a part holder in the chamber through an opening defined in a side wall of the chamber above the liquid impregnant, the opening being arranged at an angle of no greater than 45° with respect to the vertical, sealing the opening with a door, evacuating the chamber while the part is maintained above the liquid, lowering the part holder to immerse the part in liquid impregnant, releasing the vacuum in the chamber and then increasing the pressure in the chamber above atmospheric to impregnate the micropores of the part with sealant, returning the pressure in the chamber to about atmospheric, and then removing the parts from the chamber through the opening.
