Foam Injection Molding for Thin-Walled Packaging

Viscosity Reduction for Molded Parts with Large Flow Path/Wall Thickness Ratios

Foam Injection Molding for Thin-Walled Packaging

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.
