Casting is the most economical route to transfer raw materials into readily usable components. However, one of the major drawbacks for conventional or even more advanced casting techniques, e.g., High pressure die casting is the formation of defects such as Porosity . therefore it is necessary to develop new casting techniques to compensate these shortcomings . One of such casting techniques available is “Squeeze Casting” process , which has a greater potential to create less defective cast components . INTRODUCTION Squeeze casting is a relatively new casting technology when compared with traditional sand casting, which dates back to between 2000 and 3500 BC. Squeeze casting has number of advantages ,including the elimination of gas and shrinkage porosities, the reduction or elimination of metal wastage due to the absence of feeders or risers, and the possibility of the manipulation of processes to achieve the required optimum parameters. Squeeze casting can be applied to high integrity parts like suspension arms, brake calipers, aluminium wheels, steering knuckles, vanes, ring groove reinforced pistons, connecting rods, rotary compressor vanes and shock absorber cylinders, to name a few. Squeeze casting is a die casting method based on slower, continuous die filling and high metal pressures. Laminar die filling and squeezing, which is the application of pressure during solidification, ensures that the component is free from blowholes and porosity. This method produces heat-treatable components that can also be used in
