Precision think walls casting production by cast iron CHY22SH.
It is considered the technological aspects for making of precision thin walled castings from high%Aluminum Ductile cast Iron with 22 %Al, which have a reduced casting properties -high tendency to saturation with gas, oxidization and forming the scabs, and also shrinkage and gasshrinkage defects. The problem of receiving the quality castings at such conditions successfully decided by integrate of the tradition method of precision casting with innovation technical resources - by methods of computer designing and modeling, and also by the method of speed prototyping. The such of complex approach are cause at short time to develop of the making technology parameters and to appraise the quality characteristics of castings form cast Iron D22Al on the defectiveness, mechanical properties and structure.
