Streszczenie / Summary:

The paper presents analysis of the relationship between the way of pouring AlSi7Mg alloy into
moulds and misrun formation in the castings made with lost-wax casting method, with the use of
gypsum mass. The casting moulds have been filled with liquid metal with three various methods
(using gravity force, centrifugal force, and vacuum). Estimation of the quality of the obtained
castings (i.e. the degree of mould filling) allowed to assess the effectiveness of particular methods
of filling the moulds used for production of small-module castings. In result, it was found that the
highest mould filling degree is achieved with the use of vacuum technology.
