Casting Process Advantages

Casting process enjoys certain advantages vis-a-vis other shaping processes such as forging, welding, stamping, rolling, extruding, etc. The reasons for the success of the casting process are: Owing to physical properties, some metals can only be cast since they cannot be re-modelled into bars, rods, plates or other shapes. It's a process highly adaptable to the requirements of mass production.…
