Annotation Cílem této diplomové práce je konstrukce testovací vstřikovací formy. Tato forma by měla sloužit k lepšímu pochopení jevu separace fází, jenž ovlivňuje kvalitu produktů vyrobených technologií vstřikování prášků (PIM technologií). Separace fází zapříčiňuje vizuální vady, pórovitost, zborcení a tvorbu prasklin. Teoretická část diplomové práce obecně popisuje technologii vstřikování prášků, její výhody a nevýhody, proces výroby a jeho hlavní fáze - příprava směsi, injekční vstřikování, odstranění pojiva a slinování. Tato část je také zaměřena na teoretickou studii separace fází. Následující praktická část obsahuje návrh testovacího tělesa, konstrukci vstřikovací formy včetně modelu a výkresové dokumentace. Dále jsou uvedeny výsledky ze zkušebního vstřikování různých komerčně dostupných PIM kompoundů.
Annotation in English The aim of this master thesis is to design a testing injection mold, which would help us to understand a quality influencing factor in powder injection molding (PIM) - a phase separation. Phase separation might cause visual defects, porosity, warpage and cracks. There are two parts of this master thesis. The theoretical part describes PIM technology in general, its advantages and disadvantages, PIM process and its main stages - feedstock preparations, injection molding, debinding and sintering. This part also focuses on a theoretical study of the phase separation. The second part is practical and consists of a design proposal of the testing specimen, a description of a construction of the injection mold, its drawing documentation and any results from injection molding of various commercially available feedstock compositions.
Keywords separace fází, návrh testovací formy, injekční vstřikování kovových a keramických prášků.
Keywords in English phase separation, mold design, powder injection molding, metal and ceramic powders.

Research Plan The aim of this diploma thesis is step by step description of the major quality influencing factor for metal injection moulding (MIM) - phase separation. Phase separation might cause visual defects, porosity, warpage and cracks. The theoretical part of this diploma thesis generally describes MIM technology, its advantages and disadvantages, MIM process and its main stages - feedstock preparations, injection moulding, debinding and sintering. This part also focuses on a theoretical definition of the phase separation. Following practical part consists design proposal of testing injection mould, software simulations, optimization of injection moulding for various commercially available feedstock compositions. Keywords: phase separation, metal injection moulding, mould design, software simulations, debinding, sintering.
