| Summary |
|---|
| The subject is aimed at technologies of castings manufacture with the aid of modern and untraditional methods. It deals with classification of individual methods according to the casting process and the used mould type. It is an intention to acquaint students with all technologies of castings manufacture, i.e. even with that ones that are not met in the Czech Republic territory. The student will be also acquainted with technologies of casting manufacture that are used in a limited range only or for special purposes only. |
