Course detail

Machinery of Foundry Plants

FSI-PZSAcad. year: 2020/2021

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.
