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 corner cover
Hrdina, Vojtěch ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The project elaborated design of injection mould for production of corner cover, which serves to protect a reprobox from mechanical damage. The production possibilities were considered at the beginning. The injection molding technology was chosen from available technologies. The first part of the thesis is theoretic, plastics and injection molding are investigated. The choice of suitable polymer and the entire draft of mold is in the second part of thesis. The final mold is two-cavity with cold runner system. The technical and economic assessment of the proposal is carried out in the last part of thesis.

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.

Production of components "Key pouch"
Kašpar, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The main aim of this thesis is the production of injection moulds for a given component key pouch. The first part of the work describes the basic division of plastics, plastic injection technology and principles of mould construction. The second part deals with actual mould construction processed in Solidworks. The drawing documentation is the output. In conclusi-on, an economic evaluation is completed that will provide approximate cost of production moulds.

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.

Production technology of a plastic headlight panel in a car
Vrána, Petr ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
Diploma thesis which is developed for the master’s degree program (M2I – K Mechanical engineering) presents a proposal solution for production technology plastic car headlins parts from polymer material PBT GF30. Literature review summarizes the findings of thermoplastic injection technology and the structural design possibility of injection molds. The paper examined two variants of the running system, which are suitable for production of injection molding components. Finaly, after technical - economic assessment, we came to the conclusion that the better option is to use the hot runner system. In the practical part is the specified product modeled by the help of 3D software and the injection mold was designed. The design was implemented by CATIA V5 R20. For the design and manufacture of injection mold were used normality from MEUSBURGER. For the chosen alternative technology of production were made calculations and was selected injection molding machine Electron 75 – 300 from FERROMATIC.

Design of production technology of the Cover
Jelínek, Jakub ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The thesis deals with the design of the production technology of the cap, the volume of which is 700 pieces, for use in low-voltage and high-voltage equipment, including switchboards, for the production of semi-crystalline plastic polyamide 6. The component will be injection moulded into a single layer mould, which will be composed of purchased normals from Meusburger. A KraussMaffei 110-380CX machine will be used for production, which will exert a clamping force of up to 1100kN. The economic evaluation showed that for the specified production run of 700 units, the cost of the part is 479,85 CZK, the price of one piece without the initial investment in the mould and without any depreciation is over 11 CZK.
