The light metal casting industry is taking a significant step towards a greener future with the development of inorganic binder systems for core production. This approach stems from the need to reduce harmful emissions in the workplace and to create more environmentally friendly industrial processes.

Traditionally, core production has been based on organic binders, which release toxic fumes and gases into the atmosphere during the metal melting process. These volatile compounds not only pose a health risk to operators, but also contribute to air pollution. In response to these issues, inorganic binders emerge as a safer and more sustainable solution. Composed of 98-99% non-organic substances, these new binders do not produce harmful fumes, drastically reducing the environmental impact of the production process.

However, one of the obstacles to the widespread adoption of inorganic binders has historically been their sensitivity to moisture, which can compromise their stability and the quality of the finished product. To overcome this limitation, the study focuses on a two-component inorganic binder system. This innovation aims to reduce moisture absorption, improving core strength in unfavourable environmental conditions without compromising the quality of the final casting.

We will talk about this at the 37th FOUNDRY TECHNICAL CONGRESS, TUESDAY 19 NOVEMBER at 16.20 with Cristina Castiglioni and Mario Cucco
