![]() ![]() It is found that defects such as micro and shrinkage porosities, and improper solidification, are directly related to gating and risers system. Only the shape and dimensional variances of sprue/risers are taken into considerations for defects analysis. ![]() Intended for simulation simplification in this study, grain size of mold green sand, casting material quality, casting process parameters are deliberated identical for all design schemes. ![]() This study, highlighting is given on using casting simulation software which helps foundry industries to design and analysis the size and shape of the riser. Computer-aided casting simulation plays an important role in the paradigm of new product development by way of modeling entire casting processes and reveals a dynamic behavior of casting scheme in working conditions. In current casting industries, product development paradigm is shifting from traditional trial-and-error in the workshop to computer-aided casting design and simulation package by a computer(s). For a large industrial application, it needs an alternate approach that is fast, reliable and user-friendly. Filling and solidification of molten metals are very complex and difficult to simulate correctly by conservative methods.
