Improving the Quality of Production of Sand Core on Core Shooting Machines

Abstract

The article is devoted to the study of the method of modeling the core shooting process of manufacturing core from cold hardening mixtures (CHM) in the software package Flow-3D, as well as consideration of recommendations on the parameters of the core shooting process, to ensure quality castings of cast iron and steel. This technology of production of cores belongs to technologies which are widely used in foundry production.

Construction of experimental inter-operational conveying device

“…Among the mechanical operations of processing a leather product, the following are distinguished: fleshing, planing, squeezing, setting, softening, and grinding, which determine the quality of leather. The mechanical treatment of the surface of a semi-finished leather product in light industry enterprises is conducted as the main operation of the technological process, performed in order to change the geometric dimensions of the semi-finished leather product [3][4][5][6]. In [7], the rheological parameter of the inert resistance of the skin is studied.…”
