Investigation of storage conditions influence on adhesion of rubber bushings
Kvapil, Štěpán ; Muroň, Aleš (referee) ; Kandus, Bohumil (advisor)
The theoretical part of the thesis is focused on research on vulcanization and post-vulcanization, i.e. the production of rubber and the connection of rubber with metal using the latest technologies. This part serves as the theoretical basis for the development of the training base and the experimental part, which are part of the practical part. The training materials are serving for faster and more effective training of new staff and as a comprehensive set of information to the MAT center. The methodology of the manual is described in the main thesis and identical examples from this document are inserted in this thesis too. The experimental part focuses on the adhesion of rubber to the metal surface with subsequent evaluation. The whole problem from the preparation, post-vulcanization, tearing, through measurement to determination of the maximal storage life of sprayed rubber bearings is described.

Active sensors for detecting instantaneous stress and strain values
Vychopeň, Petr ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
Sensors used in engineering are divided into different kind of groups. One of them are an active sensors, which include inductive, photoelectric, thermoelectric, pyroelectric and piezoelectric. Based on literary study there are introduced, on the first place, the basic concepts related to the general characteristics of sensors, their inclusion in the measuring process and then describes the basic division, each operating principles, dependence and characteristics, specific examples of the applications in technological process and finally their advantages and disadvantages.

Optimization of technological parameters of injection plastic parts
Hamáček, Richard ; Hlaváček, Martin (referee) ; Kandus, Bohumil (advisor)
This project is dealt with optimalization of moulding procedure of plastic housing of headlamp for project DCW 204 Mopf halogen. The aim is reach a shorter injection moulding cycle time with keeping of claim quality of plastic part. Optimalization will be done based on modification of moulding pressing time. We observe warpage in axis X in the most problematical points of housing by using of contactless measuring optical technologie ATOS III Triple Scan. Simulation analysis for injection moulding was used for prediction of housing warpage up to unforming in every chosen moulding pressing time. According to reaching data in this way comparison of predicted warpage was able to done up to unforming time and real warpage of housing after unforming. According to reaching data in a different period of time warpage of housing during time flowing was observed.

Production technology flexible plastic clip
Mikulenka, Martin ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Currently, the plastics industry has a wide range of applications due to the possibility of a fully automated process or through increased production efficiencies. The reason for this choice of the thesis was to understand the whole issue of plastic injection molding process. The specified component is used to atach the sail, which serves to protect workers in the welding sector. A specified number of the series is 350 000. The work includes a theoretical problem of injection molding process, selection of technology, material selection and design of mold. An integral part of every design mold is a simulation of injection, which is also included. In conclusion of thesis is the calculation of the various stages of production and operation of the injection mold.

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.

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.
