Experimental Study of Casting using Loose Piece Pattern (Dovetail)

Abstract

One of the earliest metal-shaping techniques used by humans is casting. Typically, it entails pouring molten metal into a chamber of a refractory mould that has the desired shape before letting it cool and solidify. When the desired metal product has formed, the refractory mould is broken or disassembled to release it. When it is impossible to remove the pattern from the mould due to the part's shape, a loose piece pattern is employed. Casting faults should be decreased in order to improve the quality and productivity of any company. It is a procedure that results in some defects that give the intended product a chippier quality.
