14. MAGNA M a g n a D i g i t e c h I n d i a P r i v a t e L i m i t e d Varies steps  First we have made a 3D model of fully machined fabricated one and from there we have started identifying small components.  Due to section thickness variation we have spitted the parts into two.  To compare the casting behavior first we have analyzed the fabricated part and then our casting part. From the results we fine tuned our casting to meet the requirement. STEEL FABRICATTION TO STEEL CASTING CONVERSION
