Course objectives

The aim of Polymer Processing is to familiarise students with the machines and technologies used in industrial technologies, the moulding tools required for production and to acquire a basic knowledge of the different types of plastics, taking into account the characteristics of plastic product design, taking into account the economics of production.

Course content

Lectures

Production of polymers Thermomechanical curves, viscosity Preparatory operations Extrusion Injection moulding Special injection moulding technologies Thermoforming Bonding technologies for plastics Thermoset plastics 3D printing

Labs

Lab demonstrations. Identification of plastics by combustion. MFI measurement. Preparation operations - internal mixers, dryers, temperers. Extrusion - granulation, film blowing, tube making. Injection moulding tools, machinery, technology. Vacuum forming. Welding. Pressing of thermosetting materials. 3D printing.

Acquired competences

Knowledge

The student understands the fundamental principles of polymer structure, properties, and processability, as well as the operation and key parameters of major processing technologies. They have insight into the relationships between material structure, processing technology, and properties, along with the basics of rheological behavior.

Skills

The student is able to compare different plastic processing methods, interpret mechanical and technological parameters, and evaluate their effects on the final product’s properties. They can assess the structure and quality of processed products at an engineering level and determine optimal processing conditions.

Attitude

The student strives for an engineering-precise understanding of processing operations and approaches material selection responsibly and thoughtfully. They are open to learning about and applying new and innovative polymer processing technologies.

Autonomy and responsibilities

The student is capable of independently interpreting and selecting appropriate processing methods and responsibly setting technological parameters. They take responsibility for monitoring processes and product quality, as well as for the professional soundness of their engineering decisions.

Requirements, evaluation and grading

Mid-term study requirements

To be admitted to the exam, students have to give a short presentation on the exercise, the details of which will be explained in the first presentation. At the end of the semester, students will write 1 final examination paper, the place and time of which will be announced by the lecturer in the first week of the semester. A successful final examination paper will be accepted as an examination mark. Students must attend at least 67% of the lectures.

Exam requirements

The exam is oral, based on a pre-assigned list of questions.

Generative AI usage

Use of GAI tools is permitted in a limited manner (e.g., for literature search support or specific tools). In this case, the course instructor is responsible for defining where and how GAI tools may be used in assignments. The course description must specify in detail how GAI tools may be used during the course.

Study aids, laboratory background

Class materials are given by the lecturer.
