    Environmentally friendly foundry molding sands as a part of Green Deal policy
    (2025) Major-Gabryś, Katarzyna
    Wydział Odlewnictwa
    This conference abstract shows the results achieved within NetCastPL4.0 project. The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. The work presented during XXXI. medzinárodnej vedeckej konferencie slovenských, českých a poľských zlievačov SPOLUPRACA 2025 in Rajecke Teplice (Slovak Republik) aimed analyzing modern solutions for molding sands, both with organic and inorganic binders. In molding sands with organic binders, the innovative approach of replacing part of the binder with biodegradable additives reduces the harmfulness of molding sand at the stage of casting production a solution, molding sands with organic binders based on modified with furfuryl alcohol resins cured by hardeners with reduced sulfur content, molding technologies with alkyd resins hardened by catalyst based on isocyanates and alkaline phenolic resin hardened by esters. Molding sands with environmentally friendly inorganic binders based on sodium silicates and aluminosilicates were also analyzed.

    This conference abstract shows the results achieved within NetCastPL4.0 project. The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. The work presented during XXXI. medzinárodnej vedeckej konferencie slovenských, českých a poľských zlievačov SPOLUPRACA 2025 in Rajecke Teplice (Slovak Republik) determined the influence of molding sands’ with different inorganic binders composition on their chosen properties. The molding sands with 3 commercial inorganic binders used in traditional mold and core production technologies were tested as well as the molding sands dedicated to 3D printing with new binders based on them. Four types of hardener were used for chemical curing.
