Brief info on the course

Plastics behave very differently in the injection molding process. This has a particular effect on shrinkage during cooling. The molded part becomes smaller. Its geometry and dimensions change. Warpage occurs.

Especially newcomers to plastics technology often find it difficult to assess where the reasons for undesired warpage lie and why these reasons vary so much.

This e-learning course conveys in an illustrative form:

  • how shrinkage and warpage occur
  • which influencing factors are relevant and
  • which approach to problem solving is target-oriented.

Course description and workflow

The elearning course is divided into 10 chapters and a final test. You can interrupt, restart or repeat all 10 chapters at any point. You decide when you want to work on the course - as it fits into your daily schedule.

You can start the final test only once and receive a certificate only once. So you should be undisturbed during the final test.

Duration of work:

  • Your completion time is completely individual - you have 90 days.
  • A module that is easy for you, you might be able to complete in 30 minutes.
  • For a difficult chapter you might need more than 60 minutes - divided into several attempts.
  • Plan on at least 45 minutes for the final test

Actual completion time varies greatly by individual.

Duration of use:

After activating the booking code, the course is available for 90 days on the learning platform for processing. After successful course completion (including certificate), the online course is open for viewing until the 90 days expire.


After successful completion of the course and the final test, you will receive your certificate
