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.

This graduation theses analyse a concept of plastic plug production using the technology of injecting plastic into the form. There is performed a design of the technologic process with necessary calculations included here. Besides that the analysis is also focused on construction of the injection form. For the solution the 3D CAD system by SolidWorks and Hasco, Meusburger, Synventive normals were used. The graduation theses is finally valorized by technological-economic summary.

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.

The target of this dissertation is based on the specified shape of plastic part to develop search technology of plastic injection molds, to the technological design process and construction of injection molds, including the necessary calculations. The project includes a search and a practical sections. Based on information from a search section a suitable material was chosen, which became the basis for practical section. The practical section with basic technology calculation is complemented by filling simulation analysis and stress analysis of critical elements. A part of this dissertation is the set of the drawings.

The theory of plastic injection molding technology together with procedure of designing injection molds is elaborated in this master thesis. Also, the technology of production is designed, derived from assigned component „cover“ analysis affirmed by necessary calculations. On the bases of these calculations, injection machine fitting requirements is chosen. Then injection mold is designed for the assigned component. Simulation of injection is performed for this mold using Autodesk Inventor 2011 and its module Moldflow and then results are thoroughly analyzed. Economical evaluation for this component is then executed towards the end of the thesis.

This thesis contains of theoretical part which deals with injection molding, properties of some polymer materials are included also. Design of plastic injection mold for cover of electronic device is presented in practical part. Manufacturing parameters and injection machine selection are specified with mold structure consideration. Production costs and the final price of the plastic part are calculated in economical evaluation.

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.

The aim of this diploma work was a proposal to make the process of machining of injection mould more efficient. The work described the initial state of machining of a moulding injection part from the technological point of splinter machining, including the description of each production areas, the tool used in the process and the machines. The main part of the diploma work was focused on consideration of a possible way leading to the increase in the efficiency of the production process of machining of an injection mould part that included the transfer of the initial way of machining of a moulding injection part to CNC lathe Gildemeister CTX beta 500. Furthermore the work described the tool that had been used including the description of proposed control programs for machining of an injection mould part. The essential part of the work was a techno-economical assessment of the proposed variant of solution, which included analysis of the production costs and the time indexes that were achieved during the production.

The project developed within the Master's degree is proposing a technology of manufacturing a headlight housing from the high temperature polycarbonate Apec 1695 with wall thickness of 1.8 mm. The batch size is set at 100,000 units / year. Based on literature studies of injection moulding and also on the calculation method, the injection moulding tool with the heated injector has been proposed. The injection moulding machine Allrounder 630 S 2500-800 from Arburg is used for the production of the plastic headlight housing.

The thesis deals with risks of defect occurrences in a wood construction. Wood constructions and their parts are exposed to a number of negative factors influencing their lifetime. The aim of the thesis is to give an outline of risks of defect occurrences in a wood construction attacked by pests and propose measures for their elimination.. These steps are closely described in the individual parts and processes. Part of the thesis is the FMEA analysis, resulting in appropriate chemical protection, a factor considered before incorporation into the construction. The analysis and its outcomes are important for improvement of the wood construction lifetime.
