The following article will guide you about how to design a gating system used in casting of metal. Design of Gating System: The design of a gating system depends on both the metal and mould compositions. For example- an elaborate gating design is needed to avoid dross (e.g., oxides) in easily oxidized metals of low melting point such as aluminium. [...]
Material Properties: Alloying, Heat Treatment, Mechanical Working and Recrystallization! Method # 1. Alloying: Alloy steels are broadly classified into two categories: (i) Low Alloy Steels (ii) High Alloy Steels In low alloy steels, the total content of the alloying elements, such as Cr, Ni, Mo, V, and Mn, is kept within 5%. Each alloying element imparts a specific property to [...]
