... Abstract This article provides a discussion on ten rules for the effective production of reliable castings. These rules include good-quality melt, liquid front damage, liquid front stop, bubble damage, core blows, shrinkage damage, convection damage, segregation, residual stress, and location...

... eliminated by poor front-end design. Finally, the pressurization effect resulted in very fast delivery of melt into the mold cavity, where the high velocity (once again, much higher than the critical velocity) had the potential to create significant additional damage. Also, damage generated in the mold...
