Effect of inoculation and cooling rate on the DAS for aluminium foundry alloys
Dočekal, Václav ; Blažík, Petr (referee) ; Kaňa, Václav (advisor)
This bachelor thesis deals influence of inoculation and rate of cooling on DAS value. The aim of this thesis is primarily the effect of inoculation and formation of dendrites in aluminium alloy. The second part of thesis describe experiment. In this experimental part, is research effect inoculation of combination Ti and B. The influence of the cooling rate on the DAS value, which has been achieved by various casting processes, has also been researched. These effects, was researched on aluminium alloy-AlSi10Mg(a). The DAS has been found to affect the rate of cooling. Inoculation does not affect this value.

Construction of foundry core boxes and their use for the production of silicone parts
Skalický, Jan ; Kaněra, Miloš (referee) ; Jelínek, Radim (advisor)
The thesis deals with the design of a mold for use in casting of plastics and rubbers. The product is two different gaskets used in the testing of tubes for automotive industry. The part has a cylindrical shape with a diameter of 19 mm and a length of 25 mm, where two holes with a diameter of 4 mm are additionally drilled in one of them. Depending on the service life, the batch size is approximately 200 pieces per year. The material was not specified, so after research two options were chosen. The first was RTV-2 condensation silicone rubber LUKOPREN N 1522 from Lučební závody a.s. Kolín and the second one was RTV-2 additive silicone rubber ELASTOSIL M 4642 A/B from Wacker-Chemie, s.r.o. The second material came out better from preliminary testing. By gradually improving the design of a simple single-piece steel mold, a final version was created which is double in size and consists of three parts. It is made by 3D printing using FDM method from PLA material. It was found that in order to achieve a defect-free casting, the mix must be vacuumed before casting.
