Course detail
Machinery of Foundry Plants
FSI-PZS Acad. year: 2021/2022 Winter semester
The course makes students familiar with the basic technological equipment and machines used in foundries. A rational production of castings that would be environment friendly and would save power via automation and management of sources represents a closed circulation of materials with minimum waste material.

Learning outcomes of the course unit
Students will be cognizant of the basic manufacturing systems in foundries, the machines used, the functions and parameters of individual pieces of equipment,their
automation and deployment. All this knowledge will be extended to cover the basic
handling of materials.
Prerequisites
Knowledge of foundry technologies and metallurgy.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course-unit credit conditional on participation in seminars and proving appropriate knowledge.
Exam tests students´ knowledge of basic production nodes in a foundry plant.
Language of instruction
Czech
Aims
