Article discusses the possibilities of elimination veining. Survey, it was found that 77 % of those surveyed foundries have problems with veining, 71 % foundries solves this problem ( or try to tackle ) anti veining ingredients in nuclear and molding compounds, but only 29 % considered their " antiveining " method for successful and favourable. Characteristic defect castings of ferrous alloys, which often accompanies the use of amine - Cold box cores are veining. Method of cold-box-amine is widespread and frequently used technology for the production of cores.
