Content of teaching

Structure and properties of plastics materials,

Processing of plastics,

Behavior of plastics under environmental impacts,

Classic strength dimensioning,

Geometric dimensioning,

Plastic appropriate design,

Failure examples,

Joining of plastic parts,

Supporting simulation tools,

The workload for the lecture Design with Plastics is 120 h per semester and consists of the presence during the lecture (21 h) as well as preparation and rework time at home (99 h).


Students will be able to

  • distinguish polymer compounds from other construction materials regarding chemical differences, thermal behavior and solid conditions.
  • discuss main plastics processes regarding advantages and disadvantages of materials selection and part geometry design and to make appropriate selections.
  • analyze complex application requirements concerning material impacts on strength and to use the classic dimensioning method specific to the application to evaluate the lifetime part strength limit.
  • evaluate part tolerances and geometry by appropriate methods considering molding shrinkage, production tolerances, post shrinkage, heat expansion, swelling, elastic and creep deformation.
  • design plastic specific joining geometries like snap fits, screw bosses, weld seams and film hinges.
  • detect classic molding failures and understand potential causes as well as to reduce the probability of molding failures by defining an optimized design.
  • understand benefits and limits of selected simulation tools in the plastic technology discipline (strength, deformation, filling, warpage).
  • assess polymer classes and plastic part designs with respect to suitable recycling concepts and ecological consequences.
