The final distribution of the particles in the Liquid state processes include stir casting, compo casting solid depends on material properties and process parameters and squeeze casting spray casting and in situ (reactive) such as the wetting condition of the particles with the melt, processing, ultrasonic assisted casting [4]. Since the machining cost is then a large fraction of the overall cost, this is an area for potential cost reduction in fabricating weapon components. The process variables . In squeeze casting process, the molten metal is poured into the preheated die. Depending on the function of the casting it could be complete after ejection and trimming. As the metal starts solidifying, the upper half closes the die and applies pressure during the solidification process. Introduction Nowadays there is a great demand of lightweight parts with high . The applied pressure helps proper filling of the molten metal even at the narrow remote corner areas. Squeeze casting is a method in which molten alloy is solidified under pressure in closed dies. Pressure is implemented immediately after the liquid alloy starts to solidify and is kept on until the entire casting has solidified. High-pressure die casting is a single-step process in which the molten alloy is forced, under pressure, into a mold cavity. As the metal starts solidifying, the upper half closes the die and applies pressure during the solidification process. Lost Foam Casting No great fluidity requirements are demanded of the liquid since the displacements are small. - Low-speed filling: there is no air entrainment during mold filling, and there is no air hole defect inside the casting. Squeeze casting is a casting method that combines die casting and forging. Squeeze casting, also called liquid forging, is a hybrid metal forming process that combines permanent mold casting with die forging in a single step where a specific amount of molten metal alloy is poured into a preheated and lubricated die and subsequently forged and solidified under pressure. shao long et al. Squeeze Casting or Squeeze Forming liquid metal is introduced into an open die, even during a closed die forging process.
