Precision Casting Technology (FSI-PSL)

Academic year 2025/2026
Supervisor: prof. Ing. Milan Horáček, CSc.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: Czech
Course type: departmental course
Aims of the course unit:
 
Learning outcomes and competences:
 
Prerequisites:
 
Course contents:

Basic survey of foundry technologies, resulting in "Net_Sape" final castings.
The course provides students with basic knowledge of the individual phases of the casting processes and also gives a chance of comparing different manufacturing methods used.
This course is focused primarily to the less "conventional" technologies such as investment casting, lost foam process,  etc.
