SIC (US 1987) : Ceramic cores are sacrificial ceramic structures primarily used for forming cavities that are too small or complex to be machined within investing casting procedures. These cores are predominantly found in aerospace and industrial markets but there is a growing demand in the healthcare, sports and automotive markets.
Ceramic cores are manufactured using a porous ceramic material consisting of various compositions of Silica, Alumina and Zircon. The composition of our blends can be tailored to the customer's individual requirements.
Our compositions allow for there to be minimal interaction between the core and the metal that will be used in the casting process. The low coefficient of thermal expansion makes sure the core stays dimensionally stable when the molten metal engulfs it during the casting process. The stability of the compositions at high temperatures is very important as they allow for Morgan to manufacture our ceramic cores to the tolerances that are required by the customer. This makes our products more precise than rival casting methods such as sand casting. The materials used to make our cores are also slightly porous making it easier for them to be leeched out by chemicals, leaving behind the desired cavity.
The type of alloy being cast is also crucial - ceramic cores can be used with a wide range of alloys, including nickel and cobalt based alloys, steels, aluminium and titanium, but the match between alloy and ceramic must be appropriate. The size and complexity of the item being cast will also influence the ceramic core selection.
