Beschreibung
Zusammenfassung:	The invention relates to the metallurgy and concerns obtaining the castings subjected to cracking at hardening. A method provides for filling of fusion into the copper cast mould preheated to such a temperature that during cooling the values of thermal compression of mould and castings coincide. Fulfillment of conditions ensures the close contact of mould and castings which gives the possibility to use the mould as a holder.
