Design of manufacturing technology for plastic terminal device
Adamiec, Pavel ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
The master thesis deals with design to produce terminal using the plastic injection molding. In the first part are theoretical information about injection molding and injection molding with inserts. The second part is a concrete design of production terminal which contains: injection mold design, calculation of the injection parameters, machine selection, technical and economic evaluation of production. Terminal is made of polyamide 66, inserts material is brass. Parts of injection mold assembly are selected from Hasco standards. The main parts of assembly are made of 1.2312 steel. Production cycle is placed on injection machine Allrounder 375 V from Arburg.

Production of HTHT32 / 40 GI Double Elbow
Kříbala, Milan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The diploma thesis deals with the design of an injection mold for manufacturing double elbow, which finds its use in the siphon assembly. The part will be made of polypropylene with the trade name Tatren HT 25 11. The production batch size is set at 100,000 units in 3 months. Firstly, the analysis of the part is done including a detailed specification of its function and criteria that must be met by the component. Furthermore, a suitable technology for the production of the part is chosen. The theory of injection molding and mold design is made on the basis of the chosen injection technology. Subsequently, in the practical part is made a complete design of injection mold including technological calculations and simulations. An injection molding machine is chosen for the proposed injection mold. The conclusion of the thesis consists of technical - economic evaluation of the production of double elbow.

Optimization of wax pattern technology in the company Alucast
Šmatelka, Jakub ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
This diploma thesis deals with the problem of wax patterns manufacturing in investment casting technology (lost wax process). This technology is very sensitive to the exact execution in each phase of the whole process, from concept design up to the final casting expedition. During most operations, dimensional changes occur, which is affecting the accuracy of the final casting. No matter how big these changes are, but especially if they occur with the least variance. One of the first phases in this technology is making wax patterns. There are several ways of making the wax patterns and this thesis is describing two different methods used in the Alucast foundry. One is based on using “soft waxes” enabling using low pressure machines, the other one on the “hard waxes” where the injection machine with higher presses is being used (SOM). These two above mentioned technologies are compared in this work.

Plastics Processing Technology
Kubíček, František ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
This work is a literary research focused on plastics processing technologies with emphasis on injection moulding technology. From this field it is focused on materials suitable for injection moulding, moulding machines and parts of it, injection moulding process, defects emerging because of wrong optimalization of injection moulding process and special techniques of injec-tion moulding.

Design of technology for the production of silicone part
Dubovský, Jakub ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The focus of this paper deals very closely with the injection moulding technology. In the first part, a literature review dealing with elastomer and silicone materials is presented. This section is followed by the research of construction aspects and application of injection machines for the above-mentioned materials. General section is concluded with an analysis of injection moulding cycle and variable production methods and tools. In the second part, the proposal for production for silicone part and design of the tool is explained. It includes by examining the production conditions based on affiliated requirements, particularly the construction specifics of the designed tool. For this purpose, a technical drawing of the assembly is also made.

Design of manufacturing technology for plastic hung
Popelka, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The aim of my graduation theses is to work up the literature search of polymer processing. To give a short summary of their structure, characteristic and fabrication technique. Then to make a structural design of injection mold for producing the scheduled aim and motivate this design with requisite calculation for construction of the tool, a choice of injection machine and rundown of injection cycle. At the end of my work is this aim economically reviewed and compared with alternative form of structural design.

Production of bottle caps
Bělaška, Karel ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The master’s thesis deals with the design of an injection mould for manufacturing of a plastic bottle cap with a child safety lock. Firstly, the analysis of the part is done including a detailed specification of its function and criteria, which have to be fulfilled. After the technology is chosen (injection moulding), the analysis of the injection moulding technology and the problematics of design process is provided. In the following practical part of the thesis, the particular mould for the given part is fully designed using simulation and technological calculation. On the basis of the acquired parameters of the mould, the injection machine was chosen. At the concussion of the thesis, the technical and economical evaluation of the proposed manufacturing process for the cap with child safety lock is realised.
