The present study is concerned with the investigation of surface roughness of EN-19 steel castings. The castings were produced by investment casting process with a wall thickness of 4 mm. Experiments were conducted as per Taguchi’s L9 orthogonal array. Castings were made under the constraint of different process parameters like mold pre-heating temperature, pouring temperature, number of coats and type of sand with different grain fineness numbers to investigate their effects on the surface roughness of the final castings. The results revealed that the more number of coats significantly reduces the hardness of final castings. The surface roughness of EN19 steel increases with mold pre-heating temperature, pouring temperature whereas, better surface finish was obtained when zircon sand is used.
