Abstract
The quality of spin cast products and mould life are critically dependent on the thermal conditions they are exposed to. An investigation was carried out on the effect of air-cooling induced by the spinning of the mould and its consequences on the thermal process. A system was developed to optimise the thermal process during casting, utilising a theoretical analysis of the air-flow characteristics in a cooling tube submerged in a silicon mould and the characteristics of convection heat transfer associated with the mould and cast part. A numerical simulation of the casting process was also used in this process. The effect of the developed system on the thermal process was determined experimentally and it was found that a system of air-cooling, automatically induced from the spinning of the mould, is feasible in optimization of the thermal process.
