: Sand casting is an oldest method to accomplish obligatory shape, Every Foundry industry Requires least amount denunciation of module, Rejection Is Caused by Undesired indecision Found in Component's. Quality of casting is depends upon flow of molten metal through gating system. Unacceptable gating design is mainly in charge for the unrest and also in charge for shrinkage porosity. In other words, molten metal should enter into the mold cavity within solidification time of melt, so proper design of gating system is essential. Proper gating system design reduces the turbulence in the pour of molten metal, it also minimize air setup, sand inclusion, oxide film and dross. This paper describes the design of a gating system and feeder to produce Aluminium alloy casting of spherical component having diameter 180mm, and height 60mm the gating system with ratio of 1:4:4 (non- pressurized) and silica sand moulding method. It is crucial to recognize design of gating system and feeder for producing defect free casting. Objective of this research is to improve the quality of 7075 aluminium alloy casting by dipping defects producedin silicas and moulding process through proper gating system design and feeder design.
