Learning outcomes
|
The course provides knowledge in the field of metal forming and plastics. It provides a comprehensive view of process technologies and qualitative indicators. Students will learn to make responsible decisions about processes, organization and change in production in that field. The aim of the course is to gain knowledge of the theory and technology of hot forming and cold, familiar with the manufacturing processes of forming, acquiring knowledge of the various methods of metal forming, plastics molding capabilities and self-choice method of economic and production aspects.
