  cold shuts
In the absence of gross defects such as cold shuts, the fatigue properties of castings are largely determined by the sizes of microstructural defects, particularly pores and oxide films.
      
In addition, if the path is too long or complex, cold shuts may occur as the metal freezes before filling the cavity completely.
      
On the other hand, too slow a gate velocity means that the alloy will cool before the mold is entirely filled, causing cold shuts.
