Production of the golf club head
Žádník, Martin ; Kaněra, Miloš (referee) ; Jelínek, Radim (advisor)
Focus of this thesis is on choosing of a suitable production process of golf club head and its subsequent production. Investment casting was chosen as a process of production. Model, which is usually wax, was made on FDM 3D printer from PLA material. The casting material was chosen Maraging 200 steel. Two different putters were created and a short survey was conducted. Based on result of the survey the third model was created.
Change in production of cast iron
Sedláková, Jitka ; Jelínek, Radim (referee) ; Šenberger, Jaroslav (advisor)
The subject of this work is to validate the possibility of managing the cast iron strength through residual Mg content and to determine methodically whether it is possible to exploit this technology in a foundry. It is another subject to determine the economics of the exchange of cupola furnace for electric induction furnace and methodically assess the possibilities of melting in the electric induction furnace.
Production of castings by the Full-Mold casting using 3D printed models
Svoboda, Jaroslav ; Jelínek, Radim (referee) ; Bořil, Petr (advisor)
The aim of the work is to produce a casting using the evaporable model method with the use of 3D printed models. First, the thesis conducts a research on the topic and then discusses the process of producing a casting using this method. The PRUSA MK3S+ 3D FDM printer was chosen for the production of the model and HIPS and PMMA filaments were selected. This is followed by the selection of a model coating suitable for this technology, moulding into non-permanent sand moulds and casting the models. Finally, the final surfaces of the cast models with and without coating are compared.
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.
