摘要： The invention relates to a method for the production of molds for casting purposes, and parts of the same made of a granular, fireproof material and a binding agent, particularly shell molds, sand cores, and parts thereof. For this purpose two devices are utilized having parts, onto which a composition is applied before the use thereof, said composition comprising at least one silicon-organic component. The invention further relates to the use of such a composition for the production of molds for casting purposes, and to a corresponding device. The latter is characterized in that it comprises at least one part that is equipped with a silicon-organic layer or coating.

摘要： The invention relates to a method for producing shaped bodies, particularly cores, molds and feeders for use in foundry practice, comprising the following the steps: a) producing a composition containing: i) at least one phenol resin in solid form; ii) at least one polyisocyanate, and; iii) at least one refractory material, whereby the composition is produced at a temperature that is lower than the melting temperature of the at least one phenol resin; b) shaping the composition to form a shaped body; c) increasing the temperature of the composition above the melting point of the at least one phenol resin in order to harden the mixture. The invention also relates to shaped bodies, particularly cores, molds and feeders for use in foundry practice, which can be obtained by said method, and to a composition such as one used in this method.
