Abstract
ABSTRACT In the casting method, it is crucial to properly make the moulding design to produce sound parts. Volumetric change, especially during the solidification of spheroidal graphite cast irons, may show different behaviour compared to steel and aluminium castings. In this study, castings were carried out with single and double feeders with varying casting parameters of green sand and resin mould sand containing different cross-sectional thicknesses. Depending on the chemical composition, mould rigidity and inoculation efficiency, and the importance of the feeder path was evaluated by experimental and modelling techniques. Consequently, it was observed that the risk of shrinkage in resin moulds is less than in green sand castings in the same moulding design. In addition, it has been found that the number of feeders and neck connection is an important parameter in pore formation.
期刊介绍：
The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
