Dropping Production in the Company
Eibelová, Lucie ; Šiška, Přemysl (referee) ; Juřica, Pavel (advisor)
The bachelor thesis focuses on the reduction of administrative and error rate in manual removal of the production in the foundry. The analysis maps the current state of the processes in the operation and shows how it works. This thesis presents a proposal to solve the problem by introducing the MES system, which is installed in the foundry.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.

Casting technology in automotive industry
Andrle, Jiří ; Valášek, Petr (advisor) ; Hrabě, Petr (referee)
The goal of this work is to analyse materials and technologies used in casting process in the automotive industry. The work is divided into three main parts. The first part describes materials udes for castings. There are described ferrous materials - cast iron and tempered iron, and lightweight alloys that are increasingly used - aluminium, magnesium and titanium alloys. The next section describes casting technologies used in the manufacturing process of the car, including the innovative methods that are being implemented to automobile manufacturing process. The last part is dedicated to the development and innovation of casting technology. In particular, the simulation of casting process using computer programs that are capable of realistically simulating the course of casting. These methods are described in terms of their practical use in the manufacture of high quality castings further used in the automotive industry.

Pendulum jaw crusher 1 600 x 1 250
Ješuta, Jiří ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis deals with the design of the construction of a pendulum of a single toggle jaw crusher. The first part of this thesis treats the mechanical raw minerals disintegration. In the second part the characteristics of a single toggle jaw crusher and double toggle jaw crusher are compared. The third part addresses the calculation and the construction of the main components of the jaw crusher. Next part of the thesis consists of the calculation of the crushing force, the pendulum design, and the method of manufacturing a pendulum. The strength analysis of the designed pendulum using the finite element method (FEM) in program NX-Ideas is made in the last part of this thesis.

Application of Modern Technologies for Production of Front Part Fastening System Mountaineering Crampons
Samohýl, Lukáš ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The aim this bachelor thesis is a production of prototype front part fastening system mountaineering crampons. In this work will be carried out the design and construction of a new prototype parts using the parametric application SolidWorks. For prototype production front part crampons will be used additive method Fused Deposition Modeling - uPrint 3D printer. Part of the work will be production of silicone moulds front part crampons using vacuum casting system. Silicone mould will be used for casting of a certain number parts from commercially available materials. The work will be finished with technical and economic evaluation of production front part crampons with recommendations and the best economic analysis of alternatives.

Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.

Pendulum jaw crusher
Pitner, Jakub ; Jurásek, Jiří (referee) ; Malášek, Jiří (advisor)
This master thesis deals with structural design of pendulum for single toggle jaw crusher DC 110x70 and consists of several main parts. The first part focuses on the processing of mineral materials, especially on the process of mechanical uncoupling. The second part compares main characteristics of single toggle and double toggle jaw crushers. The third part deals with the structural nodes for the crusher DC 110x70. Another part is consisted of two variants for the pendulum construction with a comparison of the advantages and disadvantages. For the selected variant is carried out the stress control using Finite element method (FEM) in the program I-DEAS. The last part focuses on the positioning an exit slit for designed pendulum.

Verification of the original technologies used for art castings
Hřebíček, Lukáš ; Mrázek, Martin (referee) ; Horáček, Milan (advisor)
This diploma thesis is describing making of the same art casting by using different foundry technologies/ moulds (ceramic shell mould, several types of plaster moulds including anhydride gypsum and also natural sand mould). In this thesis there is also description of casting the famous piece of bull from “Byci skala” (Bull Rock). The bull was cast into traditional clay mould which is believed to be the original technology. Also the original shape of the bull casting was reconstructed, i.e. a copy of the original bull casting made. As the main achievement of this work is an overview and comparison of several technologies suitable for making art castings.
