   • 2009, Casting Design and Performance, page 123:

     When wall thickness is decreased to less than 1/16 in., adequate mold filling becomes almost impossible, except for extremely short distances, and misruns result because of the freezing of metal before the mold is filled.

   • 2010, K. L. Narayana, Production Technology, page 71:
