Production single parts from thermoplastic
Michalčák, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated in the frame of engineering studies branch N2307-00 is submitting design of a product from plastic from material PP GF30. In the frame of literal study there are summarized technical knowledge from the area of plastic processing. On its base there is selected and specified technology of plastic injection and costruction of injection mold. Thesis is further dealing with the construction of injection mold, which is solved as a 1+1 multiple with the use of side sliding flank cores. During the course of the tool construction there were used standardized elements of Hasco company. The tool will be fixed by the use of Arburg ALLROUNDER 320C injection press. In the conclusion of the thesis there are verified necessary strenght of the mold and basic production cost analyses.

Design of manufacturing technology for motorcycle headlamp body
Nosek, Jan ; Urbanec, Antonín (referee) ; Kandus, Bohumil (advisor)
The thesis is a proposal technology of the main body of motorcycle polymer material from Bayer's APEC - high temperature polycarbonate 1703. Literary study summarizes findings from a thermoplastic injection molding technology and the possibilities of structural design of injection molds, plastic plating technology from a focus on the most important technology in the field of lighting technology vehicles. Given the anticipated production run of 50 thousand. pieces are assessed a total of 2 variants of the molding parts. The practical part was modeled and specified product designed mold. Construction was done by using SolidWorks 2007 software and normalities FCPK Bytów and HASCO. For the selected option is implemented technological calculations. For the proposed technology was chosen Allrounder injection molding machine 570 A the manufacturer Arburg designed and suitable technological process of production.

Quality control of injection molded plastics using X-ray computer tomography
Figar, Erik ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
This Master‘s thesis deals with an aplication of computed tomography as the technology for quality control check of the plastic parts made by the injection molding process. The analyses were performed on two different types of plastic parts. These parts were delivered by two companies and they included the drawing documentation and CAD models. These plastic parts were analyzed according to their qualitative requirements. The analyses included evaluation of the geometric tolerances and porosity analysis with numerical and graphical evaluation. The new module for tool correction ,which is part of VGStudio Max, was tested on parts that were not in accordance with the required tolerances. Afterwards the new corrected geometries were exported. At the end of this Master’s thesis the porosity comparison was assessed between two different voxel resolution CT data. This comparison shows the complexity of this phenomenon and the importance of voxel resolution settings.

Optimization of Material Plastification Process
Šeniglová, Hana ; Krpoun, Karel (referee) ; Pantělejev, Libor (advisor)
This bachelor´s thesis deal with the optimization of the process of material plastification. The purpose of the thesis is to devise feasible parameters of a injection molding machine. The goal was achieved by the „Design of Experiments“ method. The necessary measurements were taken on the sample, a filter fuel tank, which was provided by the company Robert Bosch České Budějovice. Each measurements are described in the bachelor´s thesis. The results are summarized and evaluated in the Minitab software used for optimal parameters settings of the production process.

Production of the mold plunger
Rosa, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
The meaning of the diploma thesis is to create a new mold plunger for injection mold using a suitable method according to the original mold plunger. The final mold part should meet the required surface parameters. The work is focused on the analysis of the original mold plunger and the experimental verification of suitable methods of production of the equivalent mold plunger.

Manufacture of connector cover
Lukeštík, Tomáš ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The work presents a proposal for the production of the connector cover by injection molding from amorphous ABS polymer. Based on a literature study of injection technology and calculations, a two-part injection mold with four cavities, equipped with side sliding trolleys, was designed. The mold is composed of standardized components, some of which are modified. An Intec D100 / 380-B injection molding machine was chosen. The work is accompanied by drawing documentation of the assembly of the mold, molding plates and the designed side sliding trolleys.
