Purpose & Overview
This seminar is structured to provide designers with a fundamental understanding of the principles involved in analyzing polymer flow as related to die design. Design procedures for several types of dies and end products are explained and illustrated. Each participant receives demonstration software illustrating computer-aided analysis techniques.
Participants are urged to bring notebook computers to the seminar in order to participate in hands-on design problems.

Who should attend?
Although the seminar is presented on an engineering level, experienced die designers will also gain insights into solving complex flow problems.
