Production of prototype mold parts using rapid prototyping methods
Kaloda, Vít ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The diploma thesis pointed out the possibility of using rapid prototyping methods in the field of plastic injection, specifically to make shaped inserts into the injection mold. The universal frame of the injection mold was used and only the shaped inserts were changed. The main part of the work was the construction of an injection mold with the subsequent practical production of shaped inserts for a specified part. In the introductory part, a theoretical search was performed, about which production methods in combination with suitable materials could be theoretically used. Furthermore, the polyjet and DLP methods were chosen, which were used to produce components (core and cavity). The result of the diploma thesis was a summary of all parameters, comparison of materials and production methods. Polypropylene and polyamide 6 materials were injected into the injection mold, from which the first prototype products were made. Instructions for the production of shaped inserts with the recommended technology and material were created for the selected type, which could be used in practice.

Design of manufacturing technology for plastic program disc
Gráf, Radomír ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis is concerned with the appropriate design of manufacturing technology for plastic program disc including the design of plastic printing technology. At the beginning of this thesis was made an analysis of requirements for manufactured device including selection of the most appropriate technology for its manufacturing – plastic injection. In the theoretical part are described all skills needed for designing and construction of the injection mould. Partial theoretical parts are concerned with the issue of plastic materials, tools and engines for injection, and of plastic printing technology. Practical part is concerned with description of design of each single system inside the injection mould including calculation. On the basis of these calculations was selected the appropriate injection engine. The end of the practical part is concerned with the selection of the appropriate engine for printing on the plastic device which is manufactured by the technology of plastic injection. For construction of the injection mould were applied normalities of the Hasco Company and the 3D CAD system Solidworks. The conclusion of this thesis achieves the technical- economical evaluation for manufacturing of designed plastic device.

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.

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 mobile phone plastic cover
Přehnal, Jan ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
This project, elaborated within the Engineer Diploma studies of the 2307 branch, presents a design of a production technology of a mobile phone plastic cover. A technology of injection of plastics on the Demag Ergotech 80 injection machine has been designed on he basis of belles-lettres of injection of plastics and calculation. A shedder has been used to eject the parts. Material ABS NOVODUR P2H – AT (manufacturer: Bayer) has been used to produce the part. The mould is designed with the axial injection technology (perpendicularly to the dividing plane), closing force is 800 kN.

Production of the top of the pressure container
Sobotka, Jiří ; Císařová, Michaela (referee) ; Žák, Ladislav (advisor)
The project developed within the bachelor's degree, proposing a technological parameters of injection molding and tool design for plastic product– segment was suggested from the material PA 6 NOVAMID B30P nature. On the basis of literary study of technological plastic mould injection issues and experiences there was suggested mould injection tool with tunnel inflow, classical extractor was suggested for pressing demoulding. The mould uses standardized components and it corresponds by dimensions with production device ARBURG 420 C 1300-350 (manufacturer ARBURG Gmbh + Co KG, company Loßburg) or ENGEL VICTORY 500/120 Tech (manufacturer Schwertberg, company Schwetberg), with closing force 120 kN or 130 kN. The mould is produced from alloyed tool steel 19 436.9 (POLDI 2002).

Suggestion for rationalization of injection mould part production
Kamenická, Eva ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with suggestion for rationalization of production of an injection mould cavity plate and of a part responsible for cooling of the final plastic product. The main objective is to reduce the production time while meeting the high requirements for dimensional and geometric accuracy and surface integrity of the manufactured parts. The thesis starts with a theoretical analysis of the production of mould parts. This is followed by an analysis of the initial state of production, which consists of the characteristics of the previously mentionned manufactured parts, the available production means and a description of the original technological process. The experimental part of the thesis explains the procedures and justifies the choices made in the creation of new programmes within the CAM software Cimatron. Several possible variations of tools and cutting parameters have been experimentally tested and their final choice is justified in the thesis. The output of the thesis is a new manufacturing process for the production of both components, which has been applied in practice and evaluated on the basis of the results of testing the quality of the components and the plastic product itself. In the conclusion of the thesis can be found an evaluation of the output of the thesis and a time comparison of the previous process with the new suggestion. All experiments and measurements, including the production of the components themselves, were carried out in the toolroom of ITW PRONOVIA, s.r.o. in Veľká Bíteš, which is also the creator of the topic of this thesis.
