Design and realization of extrusion head and connecting members for extrusion of circular plastic profiles
Novák, Jakub ; Veselý, Oldřich (referee) ; Koutný, Daniel (advisor)
In this work is developed a proposal for extrusion head for extruding plastic wires of small diameter. There is a new conceptual design of cooling, which allows shape extruded products already in the extrusion head and thereby eliminates the need for large cooling tanks. To determine the optimal design is used software named Virtual Extrusion Laboratory, which is used in practice for the simulation of the extrusion process. Then it is experimentally determined behavior of plastic material, when the temperature of the melt in the extrusion head is reduced.

Influence of tempering to dimension of two-component polycarbonate molding
Svobodová, Hana ; Dočekalová, Julie (referee) ; Sedlák, Josef (advisor)
This bachelor thesis is focused on changing the dimensions of two-component polycarbonate holding during the tempering process. In the thesis there is a complete description of the production of the external lens for the automobile headlight. The experimental part is focused only on the part of the process, the tempering. The subject of the experiment is to determine the effect of the temperature in the tempering furnace and the effect of the used slats on the dimensions of the polycarbonate molding. 3D measurements are used to evaluace dimensionality. The influence of the slats is examined with free types of slats.
