Runner Design Guidlines Issue 5
In the past runner systems were designed using empirical knowledge and developed using trial and error methods which involved excessive time and often multiple die trials. Today, computer programmes exist which eliminate these problems and are able to give good results immediately but, many of the most basic design issues are often neglected during the design stage particularly if the die is designed by the tool maker without consultation to the die casting technicians.
These brief notes are intended as guidelines for use during training and as an aide memoir for die design technicians and designers.
