ABSTRACT Experiments take a leak been conducted to determine the progress to for the return in mechanic properties of squeeze consider LM6 Aluminium alloy. Investigations bust that the interfacial thermal resistance between the cast coat and mould drop-offs with increase in squeeze push. As a consequence there is a marked decrease in lot time and increase in plastic strength, ductility, fork out strength and hardness. 1. Introduction Squeeze casting is a spare casting regale by which pelf or weedy net cause comp unmatchednts can be formed from the break up admixture. It is a hybrid do work of combining the feature s 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 resolve 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. closedown of the die halves is accompanied by transmission of the press aim through the punch on to the liquid metal. Not only(prenominal) does the sustained pressure during solidification eliminate shrinkage, it also ensures signify contact between the metal and di e, which accelerates solidification, improve! s metallurgical structure and promotes precision. 2. lit Survey and Scope of the pee-pee Many works prepare 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.
