less skill is required as casting production can be more automated as opposed to the skills required for welding and fabriion more efficient use of material as "drops/crops" are not part of the material cost material costs are lower when using ductile iron as opposed to steel fabriions
the difference between casting & forging. casting is the process where metal is heated until molten. while in the molten or liquid state it is poured into a mold or vessel to create a desired shape. forging is the appliion of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.
