Gravity die casting technique proves to be advantageous for medium as well as for small volume production purpose. Gravity cast metal parts possesses exceptional mechanical attributes that make these ideal for heat treatment process. Low investment and low production cost of gravity die casting result in low cost of produced components. This metal casting process involves pouring of melted meal from ladle into die ( permanent/semi-permanent) without any stirring or turbulence to minimize porosity of produced cast metal. Manufactured cast aluminum parts are used to design cylinder head of engine, piston and knuckles to name a few.
