Thermal phenomena and rheology in the injection molding process. CAE modeling of the process. Examples. Innovative processes (co-molding, overmoulding, surface treatments.). Didactic methods
- Lectures in the classroom in person.
The topics of the course are presented through a power point presentation. The theoretical parts of the course are always followed by applications to specific case studies. Learning assessment procedures
- The exam aims to verify the level of achievement of the training objectives of the course.
In particular, the exam consists in the drafting of a project whose operational and drafting details will be illustrated during the course itself. Reference texts
