Course detail

Precision Casting Technology

FSI-PSLAcad. year: 2025/2026

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.
