This paper presents results, that were obtained after tooling white cast
iron in industrial conditions, using the method of casting modifled with
composite additions. The additions contained components which were more
favourable, and also make prime graphitization difficult. It has reached
shortening phase of cast iron graphitization, increase of R, and A5 tooled
materials, as also reasonable lowering of fitted materials hardness. The
obtained results were verified using a large slenderness ratio, which in
connection with the change of liquid delivery method, it liquified on all
lenghts of the microshrinkage and gave off prime carbon
