Design of Gating System | Casting | Manufacturing Science

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. [...]

Pattern Allowances for Proper Casting of Metals | Industries | Metallurgy

Pattern allowances in order to produce a casting of proper size and shape depend partly on product design, mould design, shrinkage and contraction characteristics of the metal being cast, etc. Actually, it is very difficult to predict precisely any rule mathematically, and a process of trial and error is best to achieve adjustment of pattern dimensions to obtain desired results. [...]
