Learning Outcomes
Competences
1. Practical Process Control and Optimization (k4): Students are able to set up an injection moulding process from scratch and optimize part quality based on process data.

2. Evaluation and Adjustment of Process Parameters (k4): Students can analyse the impact of injection moulding process parameters on part properties and make targeted adjustments to optimize quality and efficiency.

3. Process Engineering and Material Processing (k5): Students are able to apply various polymer processing techniques such as pipe extrusion, slit rheology, and compounding, and evaluate their impact on material properties.

Skills Knowledge

2. Adjust injection moulding parameters to improve product quality, such as modifying cooling times or injection velocity. (k4)

3. Analyse the impact of parameters such as injection pressure, clamping force, and temperature on part properties. (k4)

4. Perform extrusion processes to produce plastic pipes and analyse the effect of extrusion parameters on product quality. (k3)

5. Measure and interpret the flow properties of polymer melts using slit rheology techniques. (k4)

6. Mix thermoplastics with additives and fillers under controlled conditions to create specific plastic blends. (k3)

7. Identify and correct process defects such as air bubbles, incomplete filling, shrinkage, or warpage. (k4)

8. Measure and analyse parts for dimensional accuracy, surface quality, and mechanical properties. (k3)

9. Create a Protocol: Document the process setup, parameters, and results for later evaluation. (k2)
