Gravity die casting was one of the very earliest processes to be invented for metal and light alloy die casting. Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the. A gravity die casting essentially consists of following parameters such as process parameters:the process parameters which are critical and can affect the process considerably are pouring temperature:pouring. The mould cavity fills with no force other than gravity, filling can be controlled by tilting the die. Low pressure gravity die casting process from Aluminium casting processes are classified as ingot casting or mould casting. A metal die is manufactured, usually in 2 parts, to form a mould. Alpha metal industries provide explained gravity die casting process with advantages. Investacast offer gravity die / permanent mould casting, used for medium to large runs on parts that are heavier and thinner than other processes. Die casting process is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured surface metal parts. This process is done by pouring the molten metal into the mold of the pocket container. The casting technique is more effective using centrifugation, where process temperature, rotation rate, and centrifugation time can be varied. In this video of aluminium gravity die castings where molten aluminium/metal is poured into a cast iron gravity die tool. The 'gravity' part of the name refers to the fact that molten metal is poured from a vertical position into a metallic tool. Gravity die casting is a casting process in which the melt is poured from above into a permanent metal mold through a sprue. Gravity Die Casting Process / Die Casting Principles - Mechanical Engineering - No external force is applied.
