Improving casting performance through customized insulating shapes and advanced simulation techniques

Abstract

Over the years foundries have been looking for ways to improve their process. IBERIA ASHLAND and INASMET TECNALIA, together with BETSAIDE S.A.L. have implemented an innovative solution for methoding castings to ensure the integrity of the finished parts by using their latest development of customized insulating shapes combined with advanced simulation techniques. This study will show how improvements can be achieved in the mechanical characteristics of a casting by eliminating graphite deformation and shrinkage defects through the use of customized sleeves and insulating cores made of advanced moulding materials. Additionally, by utilizing the latest in simulation techniques, various compositions of the insulating materials can be "tested" effectively, allowing us to compare the final casting, without the need and related cost to produce multiple iterations of the part.
