Layout solution of a small workmanship within a given company
Bodnár, Daniel ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
Thesis is focused on machining workshop layout design for hot runner nozzle production. Production volume is 9,000 pcs/year. Theoretical part describes workflow and principles of technological design process. Based on capacity calculations, two variants of production plant layout were designed. The frist design has an area of 237 m2, the second one 211 m2. The two variants were evaluated in terms of technical and economical aspects.
Optimization of production technology for plastic cap tube
Majerčíková, Erika ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the optimization of the production technology of the cap tube made by injection molding. Series production is set at 5 000 000 units per year; the minimum time of the production is 5 years. A literary study is developed, focusing on the technology of injection molding in molds including the possibilities of the optimization of the production by changing the structure of the mold. The practical part of the thesis is devoted to the optimization of existing mold with cold runner system for the production of the cap tube, using the hot runner system supplied by Synventive. The change of the structure of the mold involves changing the three plate mold to a two plate mold. It is about changing the fixed part of the mold in which the hot runner system is placed; it is composed of standards parts of the company HASCO. Based on the technological parameters the injection machine Krauss Maffei KM 80-380 CX is chosen. There is a technical-economical evaluation of the optimization of the production by using the hot runner system at the end of the thesis.
Design of mold for plastic injection with hot inflow system
Okurka, David ; Kandus, Bohumil (referee) ; Hušek, Martin (advisor)
This thesis describes a design of an injection mould for plastic part "Sleeve", that is intended for guiding of sliding door hardware. The part is manufactured from PE-HD, production quantity is 3 000 000 pcs annually. Based on calculations and review of specialized literature the design utilizes hot runners of MH system by Ewicon. The tool is assembled from normalized components by Hasco and an injection press BOY22D was suggested for parts production. Total costs for production of 1 part are 0,26 CZK.
Design of manufacturing technology for plastic lever
Stránský, Luboš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This thesis describes the design of injection form for production of plastic lever. In the introduction,there is general literary studies of plastics and injection molding technology. Then continues studies of the injection molding machine, injection form or by selecting the gating systém. The practical part is injection mold design which includes a calculation of the injectionparameters, selection of equipment and technical and economic evaluation.
Design of manufacturing technology for plastic mount carbon
Fojtík, Jakub ; Mořkovský, Václav (referee) ; Kandus, Bohumil (advisor)
This master thesis deals with design of injection moulding technology for plastic holder of carbon brushes made of polycarbonate labelled Lexan 945A. The injection is performed into injection mould with hot runner system. Initially there is general study related to plastics and injection moulding technology. Further the study continues with injection moulds with hot runners and ends with computer analysis of injection moulding process. The designed injection mould for production of plastic holders is three-plate, double cavity mould with four hot nozzles and one parting plane, where one of the plates serves for mounting of the hot runner system inside the mould. This work contains part of the drawing documentation and item list of the injection mould. The selected injection moulding machine is Arburg Allrounder 370 U labelled 700-290 according to EUROMAP.
