Production of the mold plunger
Rosa, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
The meaning of the diploma thesis is to create a new mold plunger for injection mold using a suitable method according to the original mold plunger. The final mold part should meet the required surface parameters. The work is focused on the analysis of the original mold plunger and the experimental verification of suitable methods of production of the equivalent mold plunger.

Pall Ring Manufacturing
Wajda, Jakub ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated design of injection mould with a cold runner system for a creation of component type Pall ring made of polypropylene. Pursuant to of the literary pursuit a problem, the injection technology has been selected as the most suitable method of manufacturing. The proportions of the component along with the placement of the parting line determined the creation process of shaped cavity. The quantity of a manufacturing batch specified two-cavity as the most advantageous variant. The calculation of vent channel’s measurements, the choice of befitting injection machine and a basic simulations had been conducted. The economic part of the thesis has confirmed the suitability of usage cold runner system instead of hot runner system.

Comparison of Two Technology with Al-pressure-cast
Daniel, Jakub ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The project elaborated design of two manufacturing technologies for component called counterpart of ball from alluminum alloy. Based on the literature study and consultation with the company CNC program was made for machining technology. For pressure casting the part was modified according to the technological requirements. Comparing these technologies showed preferable method of manufacturing for mass production.

Making sand moulds and cores for casting
Katrňák, Jiří ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
Bachelor thesis describes various methods for the production of sand molds and cores in foundry and basic concepts associated with this issue. Due to the large number of production methods are described only basic and most widespread methods. The work includes the design and manufacture of cast-iron grate for the stove, made into a mixture of bentonite and self-hardening mixture AlpHasetTM.
