SECOND CERTIFICATE OF ADDITION BY improvements in the PI 9202341, BY: MACHINE FOR FILLING MOLD SAND WITH NON-FERROUS METALS BY LOW PRESSURE TECHNIQUE. The invention focuses on a MEDIA INCORPORATED PLATE FILLING MACHINES USED FILLING MOLD SAND outlined above. This means consists HAVE PLANNED ON PLATE FILLING A HYDRAULIC CYLINDER with its stem ending in a PISADOR, WITH WHICH, IN PHASE OF CASTING MOLTEN METAL ARE PRESSING THE TOP CAP MOLD, PRODUCING YOUR CRUSHING AGAINST METAL BOOK AVAILABLE IN distribution chamber, formed is between said cap and the central body of the mold. THUS, THE METAL RESERVE, WHOSE SOLIDIFICATION STARTS FROM OUTSIDE TO INSIDE AND THEREFORE STAYING FLUID IN THE CENTER OF THE SAME FOR THE REQUIRED TIME FOR MELROSE, is pushed into the mold, promoting TOTAL AND CORRECT FILLING THE SAME, EVITANDOCON thus the formation of blowholes, porosities and DEFECTS IN PART.
