Plastic materials and their treatment
Kopečný, Aleš ; Zemčík, Oskar (referee) ; Osička, Karel (advisor)
This research the basic empirical knowledge about the processing of plastic materials. The following are analyzes of the nature of plastic materials and analysis of the use of these materials in the engineering industry. This paper deals with the technological methods of processing plastics. Specifically, it is done as a summary of information about the technologies needed for the production of molds for plastics.

Weight control of soft cheese formed on a manual production line
Páral, Marek ; Zemanová, Jana (referee) ; Tomečková, Šárka (advisor)
The thesis deals with the control of the weight of soft cheeses during molding on a manual line. The theoretical part describes the classification of cheeses into groups, the basic characteristics of soft cheeses and their representatives. Furthemore, the whole technology of soft cheese production is processed and the effects on curd formation and factors influencing the weight of cheeses during molding are explained. The theoretical part ends with the basics of statistics for data processing. Basic measuring techniques (dry matter measurement, pH measurement, measurement of temperature and weight) were selected to determine the technological parameters (pH of whey, pH, dry matter and temperature of cheese grain, weight of cheese etc.) to describe the quality of grain in the experimental part of the thesis. The Design of Experiments method was used to find the optimal setting of the molding machine. Three partial experiments were designed and done. Results were verified in real production. The pH of whey was chosen to describe the grain quality. Two factors have been discovered that have a significant effect on the weigh of cheeses during molding, namely the position of the operator during molding and the amount of whey flowing into the forms with the cheese grain. The proposed molding modifications were successfully tested in production and no statistical difference was found between the weight of cheeses formed with the new setting of molding machine.

Architectural study of the sacral object Brno - Líšeň / second stage
Lyzhanov, Iurii ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor)
The main task of diploma is creating a sacral object and community centre of Salesians in Brno-Líšeň. A construction of the Salesian complex started in 1998. As a result, the whole complex of institution got to the district of Brno-Lisen with the help of the endowment fund for youth. The Congregation focuses on the methods of educating the youth of Don Bosco, the father and teacher of the youth, the first head of the Salesian. The creation of a church is a very desirable step for the Salesian Center, because Masses are currently being celebrated in the existing building in the gym, where not everything is needed to carry out of the event. The church should be developed in the vicinity of Salesian centre and has to be available for a wide range of societies. The architectural project includes the designing of church, parish building and enviroment. The form and view of the complex suit to this environmental area and react on its entire structure. The object consists of two forms, which are connected by the horizontal communication. In the middle of the Salesian complex, there is a semi-open area. The first object is a church with a capacity of approximately 200 hundred visitors, the second object is a parish building, which perform the functions of administration with multifunction space for the exhibitions, aparmtments and offices for its employees.

Design forming tool for production of cylindrical case
Fiedor, Pavel ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The project was made as a part of a bachelor’s degree study program B-STG and it proposes the concept of a molding instrument for the making of a headless bushing. The making of the given part consists of 3 operations, including widening by means of a hard instrument and flanging. The instrument is fastened into a hydraulic press CUPJ 60/10. The cutting method is used in order to prepare the semi-product. The aim of the bachelor’s thesis is to propose a technological procedure of making and processing of design documentation of an instrument for making a headless bushing.

Analysis and production of a part from an injection mold
Dudek, Ladislav ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The aim of the thesis was to make a 3D model of the injection mold for injection moulding machine, to determine the production process and to evaluate the technical and economic aspects. The first part describes the input parameters, which need to be clarified and determined before the construction of the tool. In the second part the individual parts of the injection mold and their solutions are analyzed. The third part of the thesis deals with the creation of a 3D model of mold. The program in which the model was created and the main features of the program.The fourth part describes the production process with a description of each operation.What part of the mold is the given operation introduced, what to do with the operation and why this operation has been selected. In the fifth part, two of the production operations, namely roughing and EDM, are analyzed. The sixth part describes the technical aspects that are necessary for the construction of the tool and the evaluated economic aspect. The last part summarizes the main data from the whole work.

Production single parts "Setting Base"
Dluhoš, Jan ; Henzl, David (referee) ; Žák, Ladislav (advisor)
The bachelor`s thesis, which was written on the grounds of the bachelor`s study programme B3S-P Mechanical Engineering, the field B-STG Technology in Engineering, deals with the production of moldings for transport of copy devices abroad. Molding is used for setting of the device in wooden box and it is placed on silentblocks to avoid damage of the copy device. The bachelor`s thesis contains a study of the particular issue, a proposal for the cutting machine and bending machine together with an economic evaluation.

Machines for forming technologies
Kvapil, Jan ; Henzl, David (referee) ; Podaný, Kamil (advisor)
The Bachelor thesis, which is developed in an undergraduate degree in B 2339, provides a brief overview of the various types of machines used in metal forming. The work is characterized by earlier today and used machines. The basic types of machines include: mechanical presses, hydraulic presses, hammers and rotary molding machine. All machines are described operating principles and their practical application.
