The paper evaluates technological, economic and construction aspects of the component production and the design of the tool serving for large-scale production of the S355MC steel rack component. Use of a progressive tool combining cutting and bending operations in four steps has been decided as the most appropriate according to literature study. Based on the need of production of two plane-symmetrical pieces at a time, the tool will produce both pieces simultaneously, which is economically advantageous. The tool is designed for use on the Arisa 630t mechanical press. Material will be winded off the roll, flattened and pushed into the tool by a precision feeder. The total cost of production of the component was set at 18.80 CZK.

The aim of this thesis was to design core and cavity part of the injection moulding tool with regard to the possibilities of SKD Bojkovice company. The structure of the thesis was divided into two main parts - the theoretical part, where the necessary theory for the elaboration of the second part, the practical one was briefly introduced. In the practical part own plastic component was designed, constructed an injection mold with emphasis on the core and cavity parts of the injection moulding tool and produced the necessary production documentation. Subsequently, the process of manufacturing these parts of the mold was described, and a brief technical-economic evaluation of the manufacturing process took place at the very end.

The master thesis deals with the design of geometry of plates of the injection molding unit using the FEM tool Topological Optimization. The reason for this is to reduce the weight of these components, which is beneficial in the transport and assembly of the injection molding machine. However, the final models of geometry of plates must meet certain requirements in terms of the limit state of deformation, the limit state to the critical value of the equivalent stress. This condition involves both limit state of elasticity and limit state of fatigue. Computational modeling and also Topological Optimization are performed in ANSYS Workbench.

The diploma thesis presents a production technology design of an automotive industry component – a resonator holder. The initial production run of the part is 500 000 pcs. Injection production has been selected based on variant analysis of available technologies. Technological calculations have been performed. The selected material PP 56M10 will be used for operation in granules. A quadruple shaped cavity injection mold with a tunnel gate has been designed. Based on estimated technological properties an Arburg Allrounder 470 A machine has been selected. The break-even point (BEP) shows economic return at the production of 185 595 pcs.

Diploma thesis is focused on influences on the creation and size of interpenetration layers during lacquering of polycarbonate mouldings. In the diploma thesis there is a complete description of the production of the external lens for the automobile headlight. The experimental part consists of five experiments. The subject of the experiment is to find the most optimal process settings or other solutions that would lead to positive results of chemical tests. During the tests the individual phases of the production process are examined. After each experiment follows execution and evaluation of chemical tests in the reliability laboratory.

This diploma thesis is about designing vacuum pressing device for plastics as an important method of manufacturing semi-finished plastic products. In introduction part of this thesis there is described a process of this method, the application field among the another plastics processing technologies, basic information about using semi-finished products and moulding forms. There are three versions of solution. After the estimation of this versions there is a decision about a final form vacuum pressing device. One’s own design work contains a project of a device like this with the help of Autodesk Inventor CAD system. In the end of the work, there is financial balance-sheet too.

The master´s thesis is focused on technology of injection plastics. The specified part is guard cover of mobile phone. The first part of thesis is focused on description of technology with priority on construction of form. The second part of thesis includes calculations of parameters, which are needed for production, along with techno-economic evaluation of selected construction design.

This graduation theses analyse a concept of plastic plug production using the technology of injecting plastic into the form. There is performed a design of the technologic process with necessary calculations included here. Besides that the analysis is also focused on construction of the injection form. For the solution the 3D CAD system by SolidWorks and Hasco, Meusburger, Synventive normals were used. The graduation theses is finally valorized by technological-economic summary.

The thesis focuses on the corrosion research of AlCu4Mg1 aluminium alloys of square shape and sheet metal coated in 99.5% aluminium. The theoretical part deals with the characteristics of aluminium, the classification and naming of aluminium alloys and the impact of admixtures on aluminium alloys. In the following chapter a general introduction to metal corrosion, its differentiation according to the type of corrosion attack, mechanisms of corrosion, the impact of corrosive environment, according to the choice of anti-corrosion protection, etc. is given. The main part is devoted to the corrosion of aluminium with a special importance of the impact of admixtures on aluminium alloys, the types of corrosion attack, the impact of corrosive environment as well as of the anti-corrosion protection of aluminium alloys. The corrosion tests in controlled atmosphere are considered in the next chapter, while the last one deals with the evaluation methodology of the process of corrosion. At the beginning of the experimental part all the used samples and materials are introduced. The thesis continues then with an overview and a description of the methods used for experiments. The measurement procedure and the results of the experiments are presented in the following chapter that focuses on the metallographic analysis of the aluminium alloy samples before the experiment and after the corrosion attack. The main part of the chapter deals with the dependence of corrosion speed of the individual aluminium alloy samples on time after being exposed in the climate chamber and the salt fog chamber

The aim of this diploma thesis is to ascertain the process of injecting the wax through an injection moulding machine under certain input conditions and with the help of the simulation program Cadmould 3D-F®, to perfect the injection and the following solidification of the wax. Only thanks to a perfect injection and the following solidification of the wax, a precise wax pattern can be made. In order to compare the process of injecting the wax mixture, we are helped by the Cadmould 3D-F® simulation program and the records of the injection taken by a video camera. In this thesis a simulation program used when simulating the injection of plastics was applied, as a means of comparison. In this case the similarity between the rheological characteristics of both wax and plastic was exploited.
