Design of manufacturing technology for car carpet
Kavan, David ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
The main goal of this bachelor thesis is design of a manufacturing technology for car carpet made from a thermoplastic elastomer. Car carpet will be produced by injection molding with a hot runner system in a series of 42 000 units per year. At first there is an analysis of the current technologies, enclosed with a summary of reasons for the changes in manufacturing technology. Then following is a general review of the literature relating to plastic materials and injection molding technology. In the practical part a suitable material is chosen, injection molding machine is chosen according to calculated technological parameters and a conceptual design of an injection mold for car carpet is executed. The last part is a technical and economical evaluation comparing the current production technology with the newly proposed technology.

Injection moulding machine prototype
Cikryt, Adam ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This work deals with the design of a prototype injection molding machine for the company Elzaco s.r.o. The work includes theoretical analysis which breaks down injection molding machine into individual components and describes their functionality and their important parameters. Based on the analysis and determination of critical parameters of the injection molding machine, a detailed model of the injection molding machine is created. There are also requirements for electrical components such as motors, power supplies, heaters, temperature sensors, control electronics. The method of controlling such a machine is also discussed.

Production technology of plastic unit base
Vyškovský, Stanislav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Thermoplastic injection technology is widely used in all sectors of consumer electronics and automotive industry. The biggest advantage of this manufacturing technology is a high degree of automatization and good reproducibility of the manufacturing process. Another advantage is the possibility of recycling of the gating scrap and defective products. The main task of this work is to calculate the necessary parameters for the injection process, which takes place at the designed injection form. Next part is technical design which includes choice of standard parts of injection mold and idividual semi-finished parts for mold. Thesis continues with selecting the type of injection press based on calculated parameters of the injection process. Thesis is finished by technical-economic evaluation.

Optimum layout of pressing line for the production of reflectors at Automotive Lighting
Šťastný, Michal ; Hrbáček, Jan (referee) ; Kubík, Roman (advisor)
This thesis deals with optimization of a press line part for the manufacture of reflectors present at the Automotive Lighting Company, Jihlava. The first part focuses on describing the current workplace layout of the press line. The workplaces are located inconveniently and thus require a larger number of operators and a considerable amount of manual work. The second part of the thesis proposes layout solutions for the injection presses and for other machine parts. At the same time, a smoother transition design is proposed for the press line and for the manufacturing section that follows. Based on an evaluation of selected criteria, the optimum version is chosen, thereby adding to the efficiency of the molding process by reducing the number of operators required, by lowering the proportion of manual work relative to other activities, and by limiting the risk of poor quality. The conclusion of the thesis sums up the necessary investment costs and offers an economic assessment of introducing the selected press line arrangement to operation.

Production technology of the connector body from recykled material
Brhel, Michal ; Sedlařík, Vladimír (referee) ; Kandus, Bohumil (advisor)
Study developed during the Master's degree studies of Mechanical Engineering deals with the use of recycled plastic in the injection molding and its influence on the mechanical properties of the mold. Examined product is used in the automotive industry as a connector body. The housing is manufactured from a plastic material, polyamide. The annual production volume of 3 000 000 pieces. According to tests specified in standard USCAR2 regrind influence on mechanical properties and dimensions was evaluated. After the technical evaluation of the project, research was also judged from economic point of view. In this task, savings with the different content of the recycled material during production was calculated. The final chapters justify change of properties and they are proposing the use of recycled materials in practice.

Design of injection mould for plastic component of spinning machine
Černohous, Josef ; Prokeš, František (referee) ; Koutný, Daniel (advisor)
Bachelor’s labour is concerned about present knowledge with injection moulding in first chapter, focused on machines forms, kinds of moulding materials. It also deals with technology of holding form temperature. In second chapter it engages with analysis and problem definition. Third part limits objectives of fourth part, form construction. There are single parts of moulding form closely described. Last chapter estimates construction based on it’s realization.

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.
