Foundry Technology II (FSI-PSL)

Academic year 2022/2023
Supervisor: prof. Ing. Milan Horáček, CSc.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The main goal of the course is to provide students with knowledge of broad
possibilities of casting manufacture with respect to the
chosen mould and core technology,and pouring system.
Learning outcomes and competences:
Knowledge of non-conventional foundry technologies i.e.investment
casting and lost foam technologies.
Prerequisites:
Basic knowledge of conventional methods of casting manufacture
and foundry alloys and their properties.
Course contents:
Basic survey of mould and core technologies, different possibilities of pouring liquid metal into a mould cavity.
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, vaccuum moulding etc.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Attendance in lectures is recommended, attendance in exercises is obligatory.
Credit for exercises: semestr project - obligatory
Examination : written and oral exam.
Controlled participation in lessons:
Attendance at lessons is obligatory. Absence may be compensated for by the agreement with the lecturer.
Type of course unit:
    Lecture  13 × 3 hrs. optionally                  
    Laboratory exercise  13 × 2 hrs. compulsory                  
Course curriculum:
    Lecture 1.Ceramic moulds using solid pattern-squeeze method
