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.

Design of 3 axis manipulator
Štol, Michal ; Sýkora, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with design of 3 axis manipulator which manipulate wit ball bearing and moulding of pulley. Moulding of pulley is product of injection press. Part of this work is also technical-economics valuation of manipulating possibilities with ball bearing and pulley and is determinate the most useful option. Next is work out a conception of conveyor for ball bearings and pulleys.

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.

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
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.

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.
