Design of manufacturing technology for plastic car emblem
Bombera, Mojmír ; Krška, Petr (referee) ; Kandus, Bohumil (advisor)
The project elaborated in scope of engineering studies branch 2307. The project is submitting design of production technology of car emblem. Different manufacturing technologies have been compared based on study of technical literature. Most suitable technologies have been chosen such as pressure die casting, especially aluminum alloys and plastic injection molding. Plastic part is metal plated afterwards in order to get desired metal look. Part of this project is injection molding tool design inclusive technical, technological and economic analysis.

Analysis of errors in the manufacturing process and their elimination
Kolář, Ladislav ; Fiala, Alois (referee) ; Koška, Petr (advisor)
My thesis presents the process of electromagnet production, including how the process is organised. My goal is to improve these techniques by refining them. To obtain the required data, the company's records were extracted and measurements were taken directly from the manufacturing process. Through examination of the data, any processes which created financial or temporal deficits were identified. Conclusions were then offered to solve these problem areas. These mainly involve alterations to the machinery settings, the delivery of materials and the management of production.

Design of manufacturing technology for plastic lever
Stránský, Luboš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis describes the design of injection form for production of plastic lever. In the introduction,there is general literary studies of plastics and injection molding technology. Then continues studies of the injection molding machine, injection form or by selecting the gating systém. The practical part is injection mold design which includes a calculation of the injectionparameters, selection of equipment and technical and economic evaluation.

Production technology of plastic threaded adapters
Turek, Tomáš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The Master thesis deals with the possible production of the plastic unit with thread. As the most suitable material was chosen the polyformaldehyde (POM), its production label is Delrin 500P NC010 by Du Pont. The thesis consists of a part with the information about the technology of injection molding of plastics and a part where processing parameters for the production of the plastic unit are designed. Part of the solution was to create an assembly design of injection mold. Since the plastic unit with thread is very specificly shaped the form is handled as a slide mold. The mold is pieced together from normalized parts by the Hasco and DME company. The serie of 100 000 pieces would be delivered in 5 months. Because of the cost savings a solution of the cold-runner system was suggested. A suitable injection molding machine was chosen from the calculated values from Arburgfroms – Type 370s Allrounder 500-170.At the end of the thesis costs were evalueted for acquire per one piece of adapter.

Different methods of connecting electrical parts in car locks
Kollár, Pavel ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
This Diploma thesis is aimed at various ways of connecting electrical parts in car locks. This part of the thesis includes technologies of electric cables, printed circuit boards, lead frames, 3D-MID technology and technology of electroconductive plastics materials. Listed technologies are compared. The aim of the practical thesis portion is the application of electroconductive plastic materials on the given part. For this purpose necessary changes were designed in the provided small series injection mold. The thesis also includes drawing documentation of the designed construction changes in the injection mold, as well as economic appraisal of the prototype manufacturing fees.

Design of plastic parts of the sports car front bumper
Najvar, Petr ; Drápela, Miloslav (referee) ; Koutný, Daniel (advisor)
This thesis deals with the plastic parts design for VW Scirocco R front bumper. Plastic parts were designed for an injection molding mass production. Besides of designing a shape of the parts based on package, assembly concept, functional and aesthetic requirements, great deal of attention is applied to proper part molding with regard to technological and economic aspects.

Production technology of the plastic top cover
Majerčíková, Erika ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the production technology of the plastic top cover by injection molding. Series production is set at 500 000 units, for which the required period of delivery is 9 months. A literary study is developed, focusing on the technology of injection molding in molds in the first part of the thesis. The second part is practical, which includes a design technology for the manufacturing of the plastic top cover, namely: the choice of material, determination of process parameters, the choice of the injection molding machine, and the injection mold design. The chosen material is a polyamide 6 with 30 % share of the glass. According to technological parameters of injection, the injection molding machine, Engel ES 200/65, was chosen. The injection mold is composed of standards parts of the company Meusburger and HASCO.
