<p>In an injection molding process for making thermoplastic articles, an in-runner static mixer (19, 20) is positioned near the gate (21) to a mold cavity to mix molten thermoplastic such that said thermoplastic existing the in-runner static mixer (19, 20) is more homogeneous with respect to temperature than that entering the in-runner static mixer (19, 20). Passing the more homogeneously mixed molten thermoplastic through the gate (21) to the mold cavity and allowing said cavity to fill and thermoplastic to cool, will result in an article aesthetically superior to one made by a process where no in-runner static mixing device is employed.</p> |
