Comparative Study of Rapid Ice Investment Casting Vs Rapid Casting Processes of Aluminium Alloy

Rapid casting (RC) is a phrase that refers to a specific casting process technique that reduces total production lead time. The technique for achieving it is Additive Manufacturing (AM) or Rapid Prototyping (RP). AM techniques were employed for RC to create complex shapes and sand a 3D mould from a CAD model. This article aimed to examine the performance of Rapid Ice Investment Casting (RIIC) compared with other RC processes such as Direct Wax Investment Casting (Direct Wax IC) , Lost Foam Casting (LFC), Lost PLA Casting (LPC) , and Rapid Sand Casting (RSC) . This investigation examines the part which has various geometric features. Each casting route's procedure is described in detail; pattern development, slurry preparation and mould making. Comparison of RIIC with other RC processes is studied based on the cast specimen's dimensional accuracy and surface finish. According to the findings, RIIC is preferable in terms of smooth surface finish, whereas Direct Wax IC and LFC are superior in dimensional accuracy. The article also addresses, the shortcomings of RIIC are discussed in this article, as well as proposed methods to overcome them.
