W pracy przedstawiono wyniki badań procesu produkcyjnego odlewów precyzyjnych metodą wytapianych modeli woskowych oraz projekt zmian w systemie produkcyjnym potwierdzonych filozofią nowoczesnego wytwarzania Lean Manufacturing. Pokazano schemat rozmieszczenia stanowisk oraz przebieg procesu wytwórczego. Wykazano możliwość zastosowania jednocześnie z metodyką LM komputerowego systemu ERP w produkcji odlewów precyzyjnych.

The results of investigation of investment casting production system are presented in this paper. The changes of production system are owing to Lean Manufacturing philosophy. It's shawn the layout chart of work centers of manufacturing process. It's presented that there are the possibilities of precision casting production with both items implemented simultaneously: Lean Manufacturing methodology and Enterprise Resource Planning computer system.

Shape accuracy analysis of aluminum alloy castings was made in function of ceramic mould properties. Taken it to account was anisotropy of those properties, including influence of ceramic mould properties on the porosity of castings. Ceramic moulds strains, which occur in sintering phase, were evaluated with taking into account the design and production process.

The casting workshop in Grzybiany, in Lower Silesia (SW Poland) is a valuable source of knowledge on the development of casting techniques in the 7 – 6 centuries BC. Abundant evidence found on the archaeological site points to cast manufacturing by means of precision casting in ceramic moulds (lost-wax molding). The workshop is the biggest collection of moulds for bracelet, necklace and other smaller decorative artefacts in Poland. The aim of the work is to conduct the research of the moulds and casts with the view of performing a computer reconstruction of the casting moulds from the Bronze and Early Iron Age, based on the Grzybiany finds. As part of the work, both the microscopic structure and defectoscopic analyses of the casting moulds were performed. Chemical composition of the casts was tested using the X-ray fluorescence spectroscopy method. Based on these results and using computer modelling methods, a geometric visualisation was performed, which is the bases for preparing the visualisation of the process of pouring liquid metal into the moulds, reconstructing both the technology and the alloys used.
