Foam Injection Molding for Thin-Walled Packaging
Viscosity Reduction for Molded Parts with Large Flow Path/Wall Thickness Ratios
As physical foam injection molding reduces the melt viscosity, it can be used for the production of thin-walled components. The material savings are not achieved by foaming the polymer, but rather by realizing lower wall thicknesses. The influence of the gas loading process on viscosity reduction and component quality is investigated using selected polypropylene types and an exemplary container geometry.

International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
