1 semester

The material-specific application of polymers as well as the development and design of plastic products requires a profound knowledge of the processing properties of these materials. This task is fulfilled with practical experiments on commercially available processing machines. Graduates of this module have the competence to set and optimize the process parameters of the most important processes in plastics processing in theory and practice on the basis of specified tasks and to manufacture plastic products with the required quality.

Lecture section: Plastics processing methods (blow molding, foaming, pressing thermoset processing, joining methods: Plastic welding and bonding).

Practical part: -Profile extrusion on a single-screw extruder -Film production using the extrusion blow moulding process -Thermoforming of sheets using the stretch forming and vacuum forming process -Compounding and degassing on a co-rotating twin-screw extruder -Measuring the mould locking force from the tie bar expansion of a manual injection moulding machine -Setting up, determining and optimizing the quality-relevant process parameters during injection moulding: Filling studies / sealing time determination -Injection molding of standard specimens (tie-bar-less) -Gas-assisted injection molding for the production of components with large-volume cross-sections. - Comparison of the processing of virgin and recycled material - Digitalization: process data and sensors.

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Field work / Experimental work

Experimental work (group work): approx. 8 experiments of 10 pages each

Basic knowledge of mathematics, physics, chemistry and plastics technology

After successfully completing this module, students will have a broad knowledge of the scope and key topics of plastics technology and processing. In addition to the content of the plastics technology module, this module will broaden knowledge in the field of plastics processing in the lecture section. Students will also be able to start up and optimize processes and manufacture the corresponding plastic products using industrial machinery, thereby acquiring a broad basic knowledge.

Students are able to understand the most important plastics processing methods from their own experience. They will be able to start up and operate the processes on industrial machines. They know about the product-relevant process parameters and their influence on the properties of plastic products as well as the difficulties that can arise when implementing these processes. They will have the competence to evaluate machine data and graphics, supplementary sensor data and to optimize these by means of the process parameters with regard to the required product properties.

Students learn to understand industrial processes in plastics processing through defined tasks. The resulting deepening of skills creates a qualification for solving advanced tasks that is both professionally and scientifically oriented.

Graduates of this module have the competence to work on complex industrial manufacturing processes in plastics technology in a team, to solve problems that arise, to optimize the processes and to summarize the test results in a joint scientifically structured test report.
