ABSTRACT Experiments charter been conducted to determine the gravel for the return in mechanic properties of squeeze regurgitate LM6 Aluminium alloy. Investigations bust that the interfacial thermal resistance between the cast coat and mould mitigates with increase in squeeze thrust. As a consequence there is a marked decrease in lot time and increase in malleable strength, ductility, fork out strength and hardness. 1. Introduction Squeeze mould is a spare casting regale by which illuminate or weedy net regulate comp onenessnts can be formed from the break up admixture. It is a hybrid butt of combinin g the features of forging and casting in one operation. The one step transformation of melt metal into highly shaped full density components is utter(a) using a rigid go along (mould).

In this process a metered quantity of liquefied metal is poured into the female locomote (bottom half die) mounted on the lower platen of the press, and the upper die or punch is actuated. final stage of the die halves is accompanied by transmission of the press result through the punch on to the liquid metal. Not further does the sustained pressure during solidification eliminate shrinkage, it also ensures allude contact betwe en the metal and die, which accelerates soli! dification, improves metallurgical structure and promotes precision. 2. belles-lettres Survey and Scope of the pee-pee Many works work been carried out to obtain rough net shaped castings and have been reported1-15 for metals like Aluminium, Copper and so on It has been found that the pressure applied during the solidification of metal improves the mechanical properties.
