Opis:
The paper presents an analysis incremental methods of creating wax founding models. There are two methods of Rapid Prototyping of wax models in an incremental process which are more and more often used in industrial practice and in scientific research. Applying Rapid Prototyping methods in the process of making casts allows for acceleration of work on preparing prototypes. It is especially important in case of element having complicated shapes. The time of making a wax model depending on the size and the applied RP method may vary from several to a few dozen hours.
Artykuł przedstawia analizę przyrostowych metod wytwarzania woskowych modeli odlewniczych. W praktyce przemysłowej i badaniach naukowych stosuje się coraz częściej metody szybkiego prototypowania modeli woskowych w procesie przyrostowym. Zastosowanie metod RP w procesie wytwarzania odlewów pozwala na przyspieszenie prac nad przygotowaniem prototypów. Jest to szczególnie ważne w przypadku elementów o skomplikowanych kształtach. Czas wykonania modelu woskowego w zależności od gabarytów i zastosowanej metody Rapid Prototyping może wynieść od kilku do kilkudziesięciu godzin.

Opis:
With increasing technology development, an increasing emphasis is placed on the precision of products, but cannot be guaranteed without a stable production process. To ensure the stability of the production process, it is necessary to monitor it in detail, find its critical locations and eliminate or at least control it. With such a precise manufacturing method as investment casting, such a process is a must. This paper therefore deals with monitoring the production process of wax models of large turbine blades using infrared thermography. The aim was to evaluate the critical locations of this production and to propose recommendations for their elimination or, at the very least, significant mitigation of their impact on the final quality of the large turbine blade casting.

Opis:
The authors have made an attempt to enrich the knowledge about the influence of wax pattern washing process and its influence on the quality of the shell prime coat. Two types of wax were investigated: A7Fr/60 and KC2690. A7Fr60 is used for pattern fabrication, while KC2690 is typical sprue wax. The goal of work was to establish wax solubility accuracy in Trisol 60 Plus and Houghto Clean 530 versus time and influence of dipping time to wax samples surface quality. Additionally, after exposition of wax samples, their surface morphology was characterized with the use of laser profilometry and surface roughness measurement. The quality of formed prime coat was established by X-ray tomography. The measurement of wetting angle of the wax by binder was conducted. The results have shown that the main factor which influences the quality of the prime coat is surface wettability rather than wax surface roughness.

Opis:
Until 1794, silverware and gold statue of Madonna and Child funded as a votive offering for blessings received by Jan Warzyniec Wodzicki, the Deputy Cup-bearer of Warsaw, was kept in Saint Mary’s Basilica in Kraków. Wodzicki donated several items to his parish church: in 1690 he made a gift of six altar candlesticks, in 1692 a gold statue of a Madonna and Child on a gilt silver pedestal and a pair of kneeling angels on pedestals identical to the pedestal of the Madonna statue, and on 12 July 1694 a five-piece silver antependium. In the Archive of the Wodzicki Family from Kościelniki, kept in the Ossolineum Library in Wrocław, the author of this article has found two cost estimates for making the above mentioned silverware, except for the antependium, issued in Warsaw on 9 May 1694 by Rad & Hößlin, a trading house from Augsburg. Christopher von Rad I and Bartholomäus Hößlin (Hösslin), jewellers and goldsmiths from Augsburg, established their company in 1690. The documents found by the author are the first ones to confirm that the above mentioned jewellers from Augsburg operated in Poland. The first cost estimate (Annex I) tells us that Wodzicki gave 1,100 ducats (1,114 Augsburg ducats) for the figure of Madonna and Child. The labour cost of both figures, a case and a travelling bag was 559 imperial thalers and 11 kreutzers (the cost of a wax model and forming the body out of gold sheet cost 35 imperial thalers, whereas the repoussage of the body cost 498 imperial thalers and 11 kreutzers). In accordance with the second specification (Annex II), the goldsmith was paid 1,847 imperial thalers and 30 kreutzers for the candlesticks. The labour cost of making two statues of angels on pedestals was 536 imperial thalers and 22½kreutzers, whereas making the pedestal for the statue of the Madonna and Child cost 182 imperial thalers and 78 kreutzers. The cost estimate of the silver antependium for the main altar has not survived. The inventory of Saint Mary’s Basilica in Kraków shows that the five-piece antependium weighed 206 grzywnas (ancient Polish measure of weight) and cost 14,856 tymf (Polish silver coins). The works were most probably the result of one workshop, and were perhaps by Abraham II Drentwett (1647–1729), a goldsmith, wax sculptor and draughtsman from Augsburg. During the Kościuszko Uprising in 1794, the above mentioned silverware, except for the statues of angels, were taken from the treasury of the basilica by the Order Committee established by Tadeusz Kościuszko and melted down to support the uprising. In 1807, the two statues of angels funded by Wodzicki were sold to goldsmiths from Kraków.
