Abstract

The paper presents the influence of ceramic molds manufacturing parameters on the quality of small-scale castings produced by the lost wax method. Seven ceramic coatings were applied to the prepared model kits. Three kinds of binders (LUDOX aqueous, hydrolysed ethyl silicate, Remasol water binder) and two types of molding sands (quartz and molochite) were used as ceramic material. Three types of ceramic molds were made: LUDOX ceramic/hydrolysed ethyl silicate and quartz, LUDOX ceramic/hydrolysed ethyl silicate and molochite, Remasol ceramic and quartz. After applying all of the coats, the ceramic form was dried under constant humidity and temperature conditions. Finished ceramic molds were casted with high alloy steels. Roughness tests of wax models, the first ceramic coat, initial shot blasting, sanding, and final shot blasting were performed. The results are presented in form of graphs, tables and pictures.
