Optimized ceramic shell for manufacturing of aluminium castings by using lost wax technology
Mazůrek, Tomáš ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
This diploma thesis deals with the possibilities of optimization of ceramic shell molds in the method of investment casting. In the first part is mentioned a complete technological process of the method with focusing on production and quality control of the ceramic shell and components, from which it is produced. The experimental part is divided into two parts, in the first are results of laboratory tests, which were tested both the current ceramic shell and shells which have been considered as a possible replacement. In the second section were verified conclusions of the experimental findings and recommendations of the laboratory results in pilot plant conditions.

Present state of investment casting technology
Mazůrek, Tomáš ; Zemčík, Ladislav (referee) ; Horáček, Milan (advisor)
The bachelor’s thesis elaborated within the scope of full-time study of specialization B-STI Mechanical Engineering is dealing with procedures and methods of production castings using the lost wax casting technology. This literature review deals with the entire production process from casting molds for the production models to the ultimate control of manufactured parts and is structured exactly as the technological process in the manufacture of components. For each of the technological process are given commonly used procedures and new technologies that are developed and are now examined. The second part is specific examples of the use of technology investment pattern at present. The aim of this work is to create a bibliographic search, describing the evolution of technology, investment pattern and its possible use today.

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.

Casted Formula Student Upright
Doležal, Tomáš ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
Bachelor thesis deals with a design of casted upright for Formula Student vehicle Dragon X. Casting method used for the purpose of this thesis was selected by review of relevant scientific literature. The upright was then structurally designed and strength calculations were made. Main criterion of the design is minimum compliance with meeting the required weight. Final design is compared with the design of the previous generation of vehicle.
