Validation of numerical simulation of wax filling into mother die followed by its optimization
Bochníček, Štěpán ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
The main topic of the diploma thesis is simulation of the process when wax is filling the cavity of the "mother" metal die.This knowledge is the neccessary presumption for correct design of the gating system and setting correct injection parameters (temperature, pressure, wax flow) when making wax patterns.
Investment casting waxes and measurements of their properties with regard to simulation software
Bochníček, Štěpán ; Mikulka, Vít (referee) ; Kosour, Vojtěch (advisor)
Today, the use of simulations is increasing in order to reduce cost and complexity of production and also to prevent product defects. For this purpose, we use simulation programs, such as ProCAST. This program is designed for simulation of casting parts. In my bachelor thesis I focused on the methods of casting lost wax, where the model is made of wax mixture. In each simulation we have to obtain and specify the properties of the material to casting. I described these properties and methods of measurement in this bachelor thesis.
