Production technology of plastic carrier information
Krejčí, Radek ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This bachelor's diploma thesis presents a proposal for the production technology of plastic carrier information, which is produced using injection molding technology. In the general literary study, plastic materials and injection molding technologies are analyzed. In the practical part of the thesis, the material of the plastic carrier information is selected. From the calculated technological parameters, the design of the injection mold is created and a suitable injection-molding machine is selected. Finally, a technical-economic evaluation is carried out, in which the cost of producing one piece of plastic carrier information is calculated.

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.

Sheets bonding and their testing
Straka, Jan ; Kandus, Bohumil (referee) ; Dvořák, Milan (advisor)
The aim of this bachelor thesis is to design selected load tests for bonded joints at specified steel sheet DC01 under laboratory conditions and to compare the strength of the degreased joints with technical alcohol and uncrushed joints. The basic methods of joining thin sheets are presented in the thesis. The following is an overview of test methods for bonded sheets according to the relevant technical standards. The results of the selected tests are the specific numerical values that have been compared with those reported by the manufacturer of the particular adhesive.

Design of manufacturing technology for headlamp body
Pytlík, Radek ; Tomaj, Martin (referee) ; Kandus, Bohumil (advisor)
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.

Concept of pilot project for plastics manufacturing
Tůma, Martin ; Orel, Daniel (referee) ; Kandus, Bohumil (advisor)
The aim of this thesis is design of technology project for plastic manufacturing. The theoretical part is focused on the characteristics of plastics and plastics production, especially for injection molding of thermoplastics. In the practical part are presented the calculations needed to choice of the injection molding machines and the capacity calculations to determine consumption of granulate and productivity of injection molding machines. Part of this thesis is a list of optimal machinery, including the required peripherals and handling devices complying with the current requirements of a modern plastic manufacturing. The result of this thesis is an economic evaluation of investment costs of machinery for small and medium-sized plastic manufacturing.

Production of adjustable in-line skates
Sulovský, Marek ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The thesis is focused on design of adjustable in-line skates. Using this design, users can set its length to their shoes. Adjustable length can cover up to three shoe length sizes. Traditional wood and steel designs are now almost fully replaced by plastic. Plastics are modern materials that have a lot of useful features. They have lower density than steel, while maintaining acceptable stiffness. Major part of the design can be manufactured using plastic injection molding and wheels are made by casting technology. Remaining parts include standardized stainless steel bolts with threaded inserts and aluminum rivets. Major features, setting this design apart include stable 3-wheel platform, fast Velcro fixing and built-in hex driver.
