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.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.
