Abstract
An improved die casting process for the production of castings which include metallic inserts. The process comprises the use of inexpensie non-metallic inserts in place of the metallic insert during the initial warm-up casting shots, said substitute inserts preferably being made of cardboard. The process is particularly well suited for the casting of die cast engine blocks wherein cardboard sleeves are substituted for the cast iron cylinder sleeves during the die warm-up casting shots.
