The precision Investment castings by lost wax process is the most flexible metal forming technique available and also the most cost effective way of designing and manufacturing components for a wide range of manufacturing industry. Other advantages are:
Near - net - shape of casting
Reduction in weight of casting and consequent saving in metal cost.
Close dimensional tolerance
Reduction in machining cost
Intricate design in as-cast condition, better surface finish, improved aesthetic appearance.
Greater design freedom
Wide choice of metal composition.
Feasibility of replacing two or more fabricated sub-assembly by a single piece casting.
