I would now like to return to sand castings, in contrast to pressure die castings, can make sound and leak tight. The pattern is the starting point for making mold and Figure simple pattern will be the lower half of the engine sump casting racing.
Figure the lower half-mold which some cores will be part of the waterways and the oil passages in the sump now also. It should be noted that one of the cores painted with white ceramic wash. This is the heart of the oil lobby and the customer was insistent that no grains of sand remain in 3201 Talat 8 inside of solutions that are difficult to clean. Can the upper half of the mold together also appear ready to close over. Other cylinder heads are discernible in the distance.
