Recent understanding on the effect of filling conditions on casting surface and performance of aluminum castings has resulted in design of new gating systems that eliminate damaged metal, greatly increasing casting quality and yield. It has been proposed by recent researchers that nearly all surface and internal defects in steel castings result from air entrainment during turbulent filling conditions causing unnecessary weld repair, low mechanical properties, and customer rejections. less
