In one aspect, the disclosed examples relate to a curable casting compound for producing plastics moulded parts. For example, the curable casting compound may include a binder component on the basis of a polymerisable monomer and a proportion of approximately 40% to approximately 85% by weight of one or more inorganic fillers. In one example, the casting compound includes an aluminosilicate as one of the inorganic fillers. Other examples are provided.
