Casting enables pieces to be combined into a single part, eliminating,assembly and inventory. Compared to machined parts, costs are much less. Virtually any metal that can be melted is cast.
The size can be from a few grams (for example a watch case) to several tones (marine diesel engine) the shape from simple (manhole cover) to complex (6-cylinder engine block). Order size from one-off (paper mill crusher) to massive production (automobile pistons).
Castings are used virtually every where. The transport sector and heavy equipment is the predominant consumer (for farming, construction and mining) taking up over 50% of castings produced.
A sector wise casting consumption is given below which highlights the importance of casting in any industrial set up.
