ABSTRACT
Casting process contains complex interactions with various parameters and operations related to molding, melting, degassing,
metal composition, hardening, cooling and machining. In Gravity die casting process the metals enters the mold under gravity.
Gravity die casting method is used for manufacturing of aluminium alloy oil tank. Aluminium alloy replaced many metal to
maintain quality of performance. Aim of the project is to reduce minimize the defect in aluminium alloy (LM6) oil tank casting
and improving the productivity of organization using statistical process control approach. Casting defects analysis is done by
Cause and Effect diagram or Ishikawa diagram and Pareto chart. Rejection of castings is due to blow holes, pin holes, porosity
and shrinkage finally casting defect is reduced by improving degasification step and by checking the temperature of molten
metal and mold and new design proposal is given.
