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.

Manufacture of AC / DC adapter housing
Vašíček, Lukáš ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The bachelor's thesis proposes an injection mold for the production of a plastic adapter. Based on the evaluation of the technological possibilities of the production of a plastic product, the technology of plastic injection was chosen. The first part of the work is devoted to a theoretical explanation of plastic materials, injection molds and machines. The practical part presents and develops a complete design of the injection mold, including the selection of a suitable material. The mold is designed four times with a cold inlet insert. At the end of the work is a technical - economic evaluation of production.

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 technology of plastic porter for ammunition
Hejl, Dušan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Dissertation deals with solution of production of set component „plastic porter for ammunition“. Component is made from high-density polyethylene with business marking LITEN ML 77, suggested series of 3 000 000 pieces. On the basis of literary study of plastics injection problems and necessary calculations, there was proposed injection form. This form is solved by means of normalised components from company Meusburger. There was chosen injection machine from company Arburg Allrounger 370 S 700 – 170.

Technology of injection molding of thermoplastic test specimens
Khamzin, Yersin ; Petruš, Josef (referee) ; Kučera, František (advisor)
The diploma thesis focuses on the optimization of technological parameters of plastic injection molding and the study of the influence of technological parameters on the quality of molded test specimens’ type 1A. The quality of molded parts for 3 types of polypropylene (PP) with different melt flow rate (Mosten GB 002, Mosten GB 218, Mosten MA 230) and 1 type of polystyrene (PS) (Krasten PS GP 154) was evaluated in terms of dimensional stability and weight. The contribution of software for modeling the plastic injection molding process was evaluated in this work. SOLIDWORKS Plastics software was used to optimize technological parameters. The construction of the bodies, mold and cooling system was constructed, and test bodies were produced on the basis of parameters obtained from the simulation of the injection molding process. Their quality parameters were compared with a 3D model and for each of the studied materials the optimal technological parameters were selected in terms of quality and the degree of influence of individual injection parameters on the quality of moldings was evaluated. The accordance of the results of the theoretical simulation with the real experiment was proved and a computational module independent of the optimized quality parameters, generally suitable for optimizing the quality parameters of the injected parts, was developed.

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.
