Slow Shot Profile in High Pressure Die Casting

In High Pressure Die Casting (HPDC) the plunger moves with a specified shot profile, forcing the molten metal from the shot sleeve into the die cavity. The shot profile consists of two phases: a slow shot followed by a fast shot. Hence, it has a significant impact on the amount of entrained air during the metal feeding into the die cavity. The amount of entrained air affects the porosity of the casting. The level of porosity has a direct impact …
