    2019-4-3 · The use of sand as a mold medium allows a high degree of freedom for design of high-volume parts. Since the tools only have contact with molding sand, wear is almost nonexistent. Therefore, the life of tools is a multiple of the life of ingot molds and die casting tools (approx. one million shots). This means that even for high volume partsChapter 11: Fundamentals of Casting,2011-7-25 · Risers and Riser Design Riser must be separated from the casting upon completion so the connection area must be as small as possible Figure 11-13 Schematic of a sand casting mold, showing a) an open-type top riser and b) a blind-type side riser.
