Optimization of riser neck for aluminium casting by using simulation tool
Abstract
The Gating and riser system design play very important role for improving casting yield. These defects can be reduced by making suitable changes in feeding constraints, such as feeder location, size, shape etc. and also by making some changes in feeder neck dimension. By choosing the correct set of parameters we may lead to the desired quality and yield, but difficult to achieve it. This is the reason that a need has arisen for computer aided casting simulation tool coupled with solidification simulation to reduce the number of shop floor trials and obtain enhanced yield and high quality, in minimal possible time. In this paper an auto industry part model is considered to study the solidification behaviour of aluminium alloy A356 along with detection of hot spots in castings with the help of AutoCAST XI simulation software and the effect of neck height on casting yield is also being studied.
