Polymer Technologies (LKT)


The Plastics Engineering Laboratory focuses on developing products and methods which are holistic and plastic compatible by interlinking teaching, applied research and knowledge transfer into industry. This practice-oriented approach creates the sustainable basis for economic innovative strength.

As students develop their interdisciplinary subject-specific and methodological skills, the focus is on:

Plastics expertise:

Materials and compounding

  • Thermoplastics
  • Thermosetting plastics
  • Elastomers



  • Design of injection moulding dies
  • Digitised correction and approval process


Production methods

  • Injection moulding
  • Extrusion
  • Extrusion blow moulding
  • Thermoforming
  • Pressing
  • Welding


Sectors and products

  • Mechanical engineering
  • Automotive


Methodological skills:
Agile culture

  • Scrum
  • Design Thinking
  • Kanban



  • Products and tools e. g. structured light
  • Point cloud technology
  • Reverse engineering
  • CAD / CAE



  • Life Cycle Assessment LCA


Our work is currently focusing on:

  • “Thermally conductive plastics for use in aggressive media” ZIM research project
  • Compounding for electrically conductive/magnetisable thermoplastic compounds
  • Optimised approval process for moulded parts and tools by means of Point Cloud technology
  • Plastic-compatible design and dimensioning of products
  • Dynamic strength and fatigue strength of fibre-reinforced thermoplastics
  • Sustainability in the university’s Life Cycle Analysis Competence Centre
  • Agile project management by means of scrum and design thinking
  • Variothermal tempering of injection moulding dies (thermoplastics and thermosetting plastics)
  • Design and calculation of machine settings for the injection moulding process
  • Processing of cross-linking materials in the injection moulding process


Further fields of activity are:

  • Process optimisation, automation and process control of the processing methods: injection moulding, extrusion, extrusion blow moulding, thermoforming and pressing of thermosetting plastics
  • Simulation of injection moulding and extrusion processes
  • Damage analyses
  • Identification and testing of plastics
  • Welding of plastics
