In our daily operations we observe that many defects related to shrinkage are either caused by wrong or no feeding but also by choosing the wrong riser size… that means the risers are too small or too big!
Good feeding makes the difference between a professional made casting free of shrinkage porosities with a good metal yield or castings that are produced with a bad feeding that will lead to rework and even worse to reject!
In this tutorial we show how to work with the hot spot and modulus to choose the right riser size to prevent shrinkage defects!
Besides “old school” methods… MAGMASOFT simulation the perfect tool to predict the correct riser size!
