4. Injection

4.1 Process overview

In the injection process, the molten polymer is injected under pressure into a mold, regulated at a temperature well below the polymer's injection temperature (Figure 17 ) [AM3695] . During this filling phase, the flow of liquid polymer causes the orientation and deformation of macromolecules. On contact with the mold wall, a layer of polymer solidifies very rapidly, and there is a significant...

Software tools

The simulations mentioned concern mainly laboratory work, often using "in-house" software. However, some work has used commercial software or has been funded by code developers, even if these developments have not yet been integrated into commercial versions. What's more, even if commercial software is not specifically dedicated to the development of structures, it can render estimable services by determining the mechanical...
