Estimation of solidification time and shrinkage porosity using design and process parameter of investment casting process

Abstract

Today, investment Casting is a highly specialized method of producing near net shape. Its
advantages are smooth and pleasing finish, reduced machining allowances, close tolerances, flexibility of
alloy selection etc. The steps of investment casting are wax injection, assembly; shell building, dewaxing, pouring, knock-out, cut-off and finishing. Investment casting is known for its precision casting.
In investment casting process various design and process parameters are responsible for the quality of end
product. Practically identify the effect of those parameter is vary laborious, costly and time consuming
and to overcome these problems various simulation software like ANSYS, Pro-cast, Autocast etc can be
used.
