This technology is particularly suitable for the manufacture of castings with intricate shapes and thin walls. Currently, the ablation casting process is not used in the Polish industry. This article presents the results of strength tests carried out on moulding sands based on hydrated sodium silicate hardened in the Floster S technology, intended for ablation casting of the AlSi7Mg (AK7) aluminium alloy. When testing the bending and tensile strengths of sands, parameters such as binder and hardener content were taken into account. The sand mixtures were tested after 24h hardening at room temperature. The next stage of the study describes the course of the ablation casting process, starting with the manufacture of foundry mould from the selected moulding mixture and ending in tests carried out on the ready casting to check the surface quality, structure and mechanical properties. The results were compared with the parallel results obtained on a casting gravity poured into the sand mould and solidifying in a traditional way at ambient temperature.}, type={Article}, title={The Use of Floster S Technology in Modified Ablation Casting of Aluminum Alloys}, URL={http://sd.czasopisma.pan.pl/Content/113149/PDF/AFE%204_2019_13.pdf}, doi={10.24425/afe.2019.129634}, keywords={Moulding sands, Ablation casting, Water glass, Floster S, Mechanical properties of casting, Surface quality}, }
