A method for casting cast parts in which a casting mould is provided. The casting mould is enclosed in a housing, forming a filling space between an inner surface section of the housing and an associated outer surface section of the casting mould. The filling space is then filled with a free-flowing filling material and molten metal is poured in the casting mould. As a consequence a binder of the mould material begins to vaporise and combust disintegrating the casting mould. During the filling of the filling space, the filling material has a minimum temperature, starting out from which the temperature of the filling material rises, to beyond a boundary temperature at which the vaporising binder ignites and combusts.

Method for casting cast parts

A method to produce cast pieces with optimum mechanical properties having through-openings with minimal outlay in terms of equipment. A casting mold in which at least one casting core is used. A through-channel leading through the through-opening of the cast piece is formed by burning the binder in the molding material out of the casting core representing the through-opening by means of the heat input into the casting mold when pouring the molten metal into the casting mold, or by mechanically destroying, at least in part, the respective casting core representing the through-opening and the regions of the casting mold arranged in the extension of the casting core.
