Description
  • The paper deals with the production of dimensionally accurate castings of aluminum alloys in moulds of gypsum moulding mixture. This manufacturing process is very important for the production of castings for radio technology. Castings have high dimensional accuracy and high - quality of surface. Production of aluminum alloy castings in moulds of gypsum mixtures belong to a group of non-traditional methods of casting and foundry practice, this method is used for the production of special castings. Moulds and cores from gypsum mixture have specific application not only in the production of aluminum alloy castings but cast alloys with low melting temperature (tin, zinc, lead). In these days this method produces dimensionally accurate parts with high surface smoothness such as those used for radio-communication systems or propeller small blowers. Under the conditions of the Czech foundry at our institution, the Department of Engineering Technology - TU of Liberec, we devote this method for many years. The main attention is paid to the methodology for the production of gypsum moulds and their heat treatment and the correct choice of the chemical composition of the aluminum alloy in order to obtain high-quality castings.
