Surface treatment by wet paiting
Fical, Karel ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Protection of various coating materials is today very important, both in terms of aesthetic, functional and, especially corrosion. Corrosion annually causes significant damage to metal structures and degradation of material can cause a total damage of the parts or the whole structure. When appropriate choice of coating materials can suppress the corrosion and its manifestations delay up to several years. Today, the protection of organic material coats the most common way and takes 80 to 90% of all coatings. When selecting paints and their subsequent applications we care about the material properties of the edit, its functional use, the environment in which they will be located and the properties of paint itself. To achieve satisfactory properties, it is necessary to create a technological process for the specific case.

Production of carpentry joints
Kliš, Vojtěch ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of the technology for the production of the galvanized sheet. It is a carpentry joint that serves for joining wooden structures. The work is focused on metal forming, namely cutting technology. Based on the production series of 30,000 pieces/year, the shape and dimensions of the part, the method of shearing was chosen for production. Furthermore, the necessary technological calculations were performed. The tool consists of standardized components that have been selected based on the standards. For production was chosen eccentric press S 160 E from the company Šmeral Brno a.s. The price of one component is CZK 9.

Production single parts "Case of coil winding"
Rudolf, Bronislav ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
Bachelor´s thesis is elaborated in terms of branch B-STG engineering technology. Smoothing - out suggestion manufacturing engaged plastic parts from material PA66- GF25 FR by the help of injection technology. Firstly, the basic materials for injection are described, then is described injection principle, injection mold and injection machine. The practical part deals with their own forms of construction. In the inclusion is simple economics upward revaluation expense and surplus.

The clinching technology
Urban, Martin ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
This bachelor thesis contains a description of clinching technology. Most common failures of a clinch joint, which is either a fracture at the neck of the joint or a slip of the top layer, are shown. Furthermore, this work deals with the comparison of clinching with spot welding, which lists the advantages and disadvantages of clinching technology compared to spot welding technology. A list of several clinching methods is given. Follows an overview of clinching machines and tools. And at the end are indicated some examples of the use of clinching in practice.

Production of the "Pant" component
Šidlák, Jaromír ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The thesis presents a proposal for manufacturing a basic hinge body. Together with the base, it forms an assembly that can be used, for example, in letter boxes or switchboards. The component is made of 3 mm DC01-A-m steel and has an annual production run of 10,000 pieces. The part has a galvanic zinc surface treatment. After considering possible production technologies, production in a progressive shear tool was chosen. The production process was designed to produce the hinge from steel sheets cut into strips. Based on the calculations, a suitable cutting plan was then chosen and the necessary pressing force and labour was calculated. The LEN 63 C press from the manufacturer ŠMERAL Trnava was chosen for the production. The thesis also includes designing the progressive tool, which was based on the necessary calculations. The tool itself was designed mainly from standardized parts. An economic evaluation of the design was also made. It determined the required quantity of material per production batch and the selling price of the basic hinge body, which is CZK 11.9 per piece.

Surface treatment of car body by frosted finish
Kubíček, Dominik ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
The bachelor thesis focuses on the problem of surface treatment of car body. It is dedicated to the theory of this problem, to the treatment of metal surfaces, division of different types of treatment as well as to the necessity to protect the surface from corrosion. Next part is a summary of technologic progress and application of frosted finish on the car body. In the end, we point out some mistakes caused by the violation of principles of vehicle paintwork.

Design of manufacturing technology for plastic plug
Kočí, Ivan ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
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.

Production of light holder
Němec, Miroslav ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The project elaborated design of production technology of light holder for agricultural tractors. Light holder is made of deep-drawn steel DC 01. For a production series of 30000 pieces, the production using a progressive die. The part will be manufactured in five steps. For production of the component was chosen hydraulic forming press CTH 250 of nominal force 2500kN from the company ŽĎAS. Total production costs of the component were calculated at 79 CZK.

Manufacturing of the Mobile Phone Holder
Hřebíček, Robert ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The master´s thesis is focused on the manufacture of mobile phone holder. The semi-finished productis a 1.5 mm thick steel sheetroll of S235JRG1. The annual seriesis set at 200,000 units per year. For the production of the part, the method of shearing and bending in a combined tool was chosen. Both technologies were dissected in a literary study, and a production process was developed to design a tool. A suitable production line was purchased for the entire production and the suitability of production was economicallye valuated.

Production of the component "Cable clamp"
Hráček, Josef ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The bachelor thesis deals with the suggestion of a cable clamp bracket, which is used for fastening cables. The component is made from a stainless steel sheet X5CrNi18-10 with a thickness of 2 mm and manufacturing production 200 000 pieces per year. Through comparing the manufacturing options, the production based on a progressive combination tool was chosen. By considering the viability, setting the unrolled shape, placing the part on the strip, and choosing the coil as the semi-finished product, the manufacturing process, consisting of five steps, was selected. In accordance with manufacturing methods and, technological and construction calculation the tool was constructed. Eccentric press machine S 160 E, by Šmeral Brno a.s., was selected as suitable machine. Employing economical evaluation, the market value was set at 25 Kč, with a 42% margin. The turning point was set at 38 970 pieces.
