Production of the “ Hauling lug pawl“ component
Jansa, Slavomír ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
This magister thesis focuses on possibilities of replacement of milled Hauling lug pawl by cheaper component made by MIM technology with additional chemical-thermal treatment. Two thirds of costs should be saved if application is fruitful. Despite huge mix of combinations of steel ASTM-A29-AISI 8620, ASTM-A29-AISI 4140 and chemical-thermal treatment, no combination was successful. Several series of samples have been created but not even the use of HIP and ARCOR technology helped to pass circuit breaker storage life tests. Successful application of MIM technology would require additional design changes or choice of different suitable part.

Manufacturing possibilities of slider
Chládek, Martin ; Havliš, Stanislav (referee) ; Podaný, Kamil (advisor)
Project drawn up as a part of bachelor studies of mechanical engineering branch brings suggestion of technologies that are usable for manufacturing of slider, which is a part of turn restrictor mechanism produced by the company TOKOZ, and presents assessment of its suitability. Considered technologies are casting, metal injection molding (MIM), combinations of non-conventional methods of material separation and bending, conventional cutting and bending, cutting and roll forming and precision cutting and bending. Upon a comparison of attributes of these technologies especially in term of precision requests, one piece manufacturing expenses and manufacturing time demands was chosen as the most suitable option with regard to productivity combination of conventional cutting and bending and with regard to manufacturing precision combination of precision cutting and bending.
