Abstract
The article considers the strength issues of foundry cores manufactured by the Cold‑box‑amine process. It is shown that the properties of the core mix can be controlled by adjusting the formulation. Examples of the influence of binders’ consumption on the properties of the mixes are given: a decrease in resin and polyisocyanate leads to a decrease in strength and a decrease in life. In addition, the minimum consumption of binders varies from manufacturer to manufacturer. Recipes of mixes with special additives are given, which allow, by reducing the strength of the mix, to ensure the completeness of the polymerization reaction.
