Learning outcomes of the course unit
– Ability to choose polymeric materials for components.<br />
– Ability to choose the technology of plastic part production.<br />
– Ability to respect technological limitations in the design of plastic parts.<br />
– Ability to produce a plastic prototype by molding or casting plastics.
Prerequisites

Planned learning activities and teaching methods
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
– passing a theory test (max. 50 points),<br />
- active participation in exercises (max. 20),<br />
- submission of a technical report (max. 30 points).<br />
Aims
Graduates will be able to choose a suitable polymeric material and respect technological limitations in the design of plastic parts.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is recommended; attendance at laboratory practicals is obligatory and checked by the lecturer. Compensation of missed lessons depends on the instructions of course supervisor.
