Using Assisted Injection Moulding (AIM) Technologies to Reducde Cost and Improve Quality
By James Jenkinson and Clare Goodall, Cinpres Gas Injection
 

A full shot moulding is filled to at least 100% of mould cavity volume with plastic during the plastic filling stage.  Gas is then injected and flows into the component to compensate for the plastic shrinkage.  The rate of flow of gas into the component is controlled by the rate of plastic volume shrinkage. The amount of gas flow into the component is limited by the shrinkage of the material...

Optimal Plastics Material Selection
By Dr. Chris O'Connor Eaton, Smithers Rapra

Despite the advances in manufacturing and design technology, it is a fact that around 70% of plastics fail before their design lifetime, resulting in litigation, expensive recalls, warranty claims, re-tooling and, in an ever competitive market – loss of brand credibility. So where is the issue?   From the 5000 plastic product failures which have been the subject of extensive study at Smithers Rapra we conclude that the problems often arise at the design stage...
