learning objectives:

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.
