Abstract
An experimental study of the effect of mold surface
roughness on in-process in-flow linear part shrinkage in
injection molding has been carried out. The
investigation is based on an experimental two-cavity
tool, where the cavities have different surface
topographies, but are otherwise identical. The study has
been carried out for typical commercial polystyrene and
polypropylene grades.
The relationship between mold surface topography and
linear shrinkage has been investigated with an
experimental two-cavity mold producing simple
rectangular parts with the nominal dimensions 1 x 25 x
50 mm (see figure 1). The cavities have different
surface topographies on one side, but are otherwise
identical (see discussion of other contribution factors).
