C. Draft angle on the side walls of the en-closure. First, compute the draft for the in-side surface, using the same draft data from the Standards as for the fins. C = 30 L = 1.50 (38) Therefore D = 0.041 (0.21) A = 1.56o Use 1.5° minimum, preferably 2°. Although the computed minimum draft on the outside surface is one-half as much, spec-

The North American Die Casting Association (NADCA) has standard specifications for setting high pressure die casting tolerances. There is also the international ISO standard series, which focuses on casting tolerances. This series replaces the former ISO 8062:1994. ISO 8062:1994 did not have specifications to high pressure die castings.

Draft is the angle, which must be allowed for on all vertical faces of a pattern to permit its removal from the sand mold without tearing the mold walls. The amount of draft depends upon the size of the casting, the method of production, and whether molding is performed by hand or machine. Machine molding will require a minimum amount of draft.
