Abstract
One way to produce shaped ingots with the minimum percentage of rejects is casting into sandy-resin (shell) molds (SRM). Various technologies are used to obtain SRM: the temperature impact, pressing, using various binders, etc. The factors listed lead to the improvement of some performance indicators, in particular, tensile strength and surface roughness, i.e. contribute to the quality of the ingot. This allows recommending to produce shaped ingots of white cast iron using sand and resin molds, while the quality and life time of the ingot compensates for some increase in the cost of the product.
