Production technology of plastic parts for automotive industry
Šobáň, Jakub ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
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.

Design of manufacturing technology for plastic cogwheel
Vyhnanovský, Jaroslav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This project has been developed within the master study of Engineering Technology and Industrial Management a design of manufacturing technology for plastic cogwheel is introduced. The cogwheel will be produced by plastic injection moulding. POM material with a trade name Delrin 100 NC010 from DuPont Company will be used. An injection mould is a tool for producing a plastic cogwheel using injection moulding technology. Production will take place on the machine Allrounder 420 C Golden Edition 1000-290 from Arburg German Company headquartered in Loßburg, where the seat of parent company is situated.

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.

Production technology of plastic body aperture
Dluhoš, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the production of a plastic body of the aperture by the method of injection moulding. The work includes a design of the injection mould for the given component. First, an appropriate material for the moulded piece was chosen and then the necessary calculations for the injection mould were made. A quadruplex injection mould with a heated inlet nozzle and pullout cores was designed based on these calculations. Modular components were chosen when designing the injection mould. The next part of the thesis contains the selection of the injection moulding machine for the given mould. The conclusion contains a technical-economical evaluation including the cost estimating for the injection mould and cost estimating for one moulded piece.

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.

Comparison of production possibilities gears plastic and metal
Květoun, Jan ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
This project is focused on comparison technologies of making cogwheels from plastic and metal. Inside are described principles, descriptions of technologies and appropriate usage or advantages and disadvantages. Mentioned technologies of making metal gears are primarily machining for example milling, slotting or grinding. Making of plastic gears is primarily focused on injection moulding. Practical part of this thesis is focused on exchange metal cogwheel with plastic cogwheel with helping calculations and information from resources. Exchanged cogwheel is from motorcycle ČZ 175/453.

Application of Modern Technologies to Concept of Production of Car Part Prototype
Bachorík, Patrik ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The objective of my bachelor thesis is the design and manufacture of a prototype component for automobile industry. Specific designs and parameters of the prototype component were constructed in 3D parametric software Autodesk Inventor. Additive method Fused Deposition Modeling – a 3D printer uPrint was used for the production of the prototype component. A part of my work was the manufacturing of a silicone form with the use of a vacuum – moulding system. The purpose of this form was casting the required number of prototype components made of commercially available materials. Also, metrologic measuring of the pieces was carried out using 3D measuring machine with the aim of evaluation of manufacturing tolerance limits compared to the engineering drawing. The work was finished with technical and economic evaluation of the manufacture process of the prototype component with the subsequent analysis and overall assessment of the most convenient economic variant.

Scrap Analysis in Manufacturing Process
Buriánková, Alena ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
The master’s thesis is focused on the reduction of rejection rate in production of plastic bowls with the use of statistic methods. The theoretical part of this thesis describes among others Statistical Process Control, Process capability and types regulatory diagrams. The basis for the practical part is data collection over a certain period of production, from which the percentage of the rejection rate is evaluated. Experiments and corrective actions are designed to improve the process and thereby reduce scrap.

Injection moulding
Heralt, Aleš ; Balej, Zdeněk (referee) ; Žák, Ladislav (advisor)
This Bachelor´s thesis is focused on construction forms for injection of thermoplastic matters. The technology for plastic products production is technology that participate more and more in production of all sorts of products - from technical components over kitchenware after as much as toys. Main part of this thesis is focused on description of the injection valve, ejector, annealing and ventilation system forms for injection with the main structural principles.
