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.

Design of manufacturing technology for plastic cogwheel
Vyhnanovský, Jaroslav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This project has been developed within the master study of Engineering Technology and Industrial Management a design of manufacturing technology for plastic cogwheel is introduced. The cogwheel will be produced by plastic injection moulding. POM material with a trade name Delrin 100 NC010 from DuPont Company will be used. An injection mould is a tool for producing a plastic cogwheel using injection moulding technology. Production will take place on the machine Allrounder 420 C Golden Edition 1000-290 from Arburg German Company headquartered in Loßburg, where the seat of parent company is situated.

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.

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.

Passive sensors for detecting instantaneous stress and strain values
Jašek, Petr ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
Technical measurements are an indispensable source of information in the technical fields. Due to the computer processing it is necessary an electrical signal as the output of the sensor. The field of measuring techniques of non-electrical quantities comprises a wide range of various sensors. Passive sensors represent an important group, into which resistive, inductive, capacitive, magnetic and ionization sensors are arranged. Basic findings of measurement are presented, and particular kinds of sensors, their functional principles, application examples and evaluation of their properties are described in the thesis.

Different methods of connecting electrical parts in car locks
Kollár, Pavel ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
This Diploma thesis is aimed at various ways of connecting electrical parts in car locks. This part of the thesis includes technologies of electric cables, printed circuit boards, lead frames, 3D-MID technology and technology of electroconductive plastics materials. Listed technologies are compared. The aim of the practical thesis portion is the application of electroconductive plastic materials on the given part. For this purpose necessary changes were designed in the provided small series injection mold. The thesis also includes drawing documentation of the designed construction changes in the injection mold, as well as economic appraisal of the prototype manufacturing fees.

Production technology of plastic unit base
Vyškovský, Stanislav ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
Thermoplastic injection technology is widely used in all sectors of consumer electronics and automotive industry. The biggest advantage of this manufacturing technology is a high degree of automatization and good reproducibility of the manufacturing process. Another advantage is the possibility of recycling of the gating scrap and defective products. The main task of this work is to calculate the necessary parameters for the injection process, which takes place at the designed injection form. Next part is technical design which includes choice of standard parts of injection mold and idividual semi-finished parts for mold. Thesis continues with selecting the type of injection press based on calculated parameters of the injection process. Thesis is finished by technical-economic evaluation.
