Abstract

This work is devoted to the determination of the optimal technology for manufacturing castings from the АК7ч. alloy (Al–Si systems) by the method of investment casting. Data on the capabilities of the investment casting method are given. The data on the basic requirements for the ceramic shell, as well as the method of its production and application, are presented. An experiment was conducted to determine the required number of layers of ceramic coating for aluminum castings of various configurations. On the basis of the analysis of the results of the work, the optimal number of applied layers was chosen for the production of model blocks and the method of shell molding.
