Design of plastic parts of the sports car front bumper
Najvar, Petr ; Drápela, Miloslav (referee) ; Koutný, Daniel (advisor)
This thesis deals with the plastic parts design for VW Scirocco R front bumper. Plastic parts were designed for an injection molding mass production. Besides of designing a shape of the parts based on package, assembly concept, functional and aesthetic requirements, great deal of attention is applied to proper part molding with regard to technological and economic aspects.

Design of manufacturing technology for motorcycle headlamp body
Nosek, Jan ; Urbanec, Antonín (referee) ; Kandus, Bohumil (advisor)
The thesis is a proposal technology of the main body of motorcycle polymer material from Bayer's APEC - high temperature polycarbonate 1703. Literary study summarizes findings from a thermoplastic injection molding technology and the possibilities of structural design of injection molds, plastic plating technology from a focus on the most important technology in the field of lighting technology vehicles. Given the anticipated production run of 50 thousand. pieces are assessed a total of 2 variants of the molding parts. The practical part was modeled and specified product designed mold. Construction was done by using SolidWorks 2007 software and normalities FCPK Bytów and HASCO. For the selected option is implemented technological calculations. For the proposed technology was chosen Allrounder injection molding machine 570 A the manufacturer Arburg designed and suitable technological process of production.

Production single parts from thermoplastic
Michalčák, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated in the frame of engineering studies branch N2307-00 is submitting design of a product from plastic from material PP GF30. In the frame of literal study there are summarized technical knowledge from the area of plastic processing. On its base there is selected and specified technology of plastic injection and costruction of injection mold. Thesis is further dealing with the construction of injection mold, which is solved as a 1+1 multiple with the use of side sliding flank cores. During the course of the tool construction there were used standardized elements of Hasco company. The tool will be fixed by the use of Arburg ALLROUNDER 320C injection press. In the conclusion of the thesis there are verified necessary strenght of the mold and basic production cost analyses.

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.

Application of quality control tools
Dubská, Markéta ; Hůlová, Marie (advisor) ; Kořánová, Helena (referee)
This bachelor's thesis focuses on a quality management in the enterprise JE Plast s.r.o. The aim is to suggest possible ways of improving the quality of processes and production in the company and to show the potential use of the seven quality control tools. The work is divided into two parts -- theoretical and practical. Firstly, it describes theoretical concepts of quality and approaches to its management. Further, it deals with quality control legislation and provides an overview of quality management tools. In the practical part, there is description of the company JE Plast s.r.o. After that, the tools for specific production are applied. For this purpose, the author used data obtained during the monthly monitoring of production in the company. Finally is presented the evaluation of the resulting outputs and proposal how to make manufacturing processes more efficient. Outputs will be further delivered to the company JE Plast s.r.o.
