CAE in Polymer Processing

Elongational Flows in Polymer Processing

Mechanical CAE in Automotive Design

The urgent issues for automobile companies today are how to reduce the time and cost required for developing a new car. CAE ( Computer Aided Engineering ) has been regarded as an efficient way to solve these issues, and as a numerical experiment to replace prototypes and experiments. CAE was first introduced to reproduce phenomena that are elusive in regular experiments. Now it is even capable ...

Understanding Polymer Processing

Computer Modelling of Polymer Processing

The gas assisted injection moulding (GAIM) process has benefits realised through material saving, improved product performance and lower capital cost of machinery. This important process is similar to conventional injection moulding in so far as polymer melt enters a cavity under pressure. However, before the melt completely fills the cavity, nitrogen gas is introduced into the melt at high pre...

Advances in Polymer Processing Additives (PPA)

In previous work, flow visualization was used to understand how polymer processing additives (PPA) eliminate sharkskin in linear low-density polyethylene (LLDPE). The PPA migrates to and coats the die wall, induces slippage, and eliminates sharkskin. In this work, the interface between the PPA and LLDPE was further characterized using reflection light microscopy, scanning electron microscopy, e...
