Process Variables Cavity Fill ( HPDC )

The HPDC machine with a horizontal shot end has a significant disadvantage over other die casting processes. The metal is introduced using a horizontal sleeve. This process provides opportunity for temperature loss, metal contamination, air entrapment, frictional losses due to the sleeve and tip, and a 90 degree turn in the metal path. The shot end process can help to minimize the temperature loss and air entrapment through control of several process parameters before the metal reaches the cavity. These process parameters are:
