The course assumes no prior knowledge about plastic part design. Many existing plastic products and new products converted from metals are redesigned in order to simplify production and reduce costs. Designers have to be aware of the unique nature of plastics and how to effectively design with these materials if useful products are to be made. Existing plastic part designers will need to update their knowledge base to effectively design parts from new high performance polymers for medical, automotive and aerospace applications in particular.
Tuesday mornings – 3 x 1 hour sessions: 9.00am, 10:30am & 12noon.
All sessions will be recorded so if you miss a session you can catch up by viewing the recorded session.
Upon completion of the course a candidate will be able to:
- Construct a basic polymer product design specification
- Design a basic polymer product from first principles
