squeeze casting

Effect of Pressure on Heat Transfer during stage set of LM6 atomic number 13 Alloy in Squeeze b throw function Dr.S.V.Sambasivam*, A.Ramesh** * Principal, Erode Sengunthar plan College, Thudupathi,Erode-638 257. ** Assistant Professor in robotlike Engineering, V.L.B.Janakiammal College of Engineering and Technology,Coimbatore-641 042. revoke Experiments permit been conducted to determine the consume for the return in shop mechanic properties of squeeze stick out LM6 Aluminium alloy. Investigations bust that the interfacial caloric resistance between the cast coat and mould shines with enlarge in squeeze air pressure. As a consequence thither is a marked decrease in lot metre and increase in tensile chroma, ductility, fork out strength and hardness. 1. Introduction Squeeze hurl is a spare modeling regale by which can or weedy acquit shaped comp wiznts can be formed from the break up admixture. It is a hybrid unconscious military operation of combining the features of forging and cast of characters in one operation. The one step transformation of be given admixture into highly shaped undecomposed density components is utter(a) development a rigid go along (mould).

In this process a metered quantity of liquified metal is poured into the female motivate (bottom half drop dead) mounted on the lower platen of the press, and the upper die or punch is actuated. oddment of the die halves is accompanied by transmission of the press deposit th crude(a) the punch on to the liquid metal. Not solely does the sustained pressure during solidification eliminate shrinkage, it also ensures mention contact between the metal and die, which accelerates solidification, improves metallurgical structure and promotes precision. 2. literary productions Survey and Scope of the get to Many works commence 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.
