    摘要: In an injection molding process for making thermoplastic articles an in-runner static mixer is positioned near the gate to a mold cavity to mix molten thermoplastic such that said thermoplastic exiting the in-runner static mixer is more homogeneous with respect to temperature than that entering the in-runner static mixer. Passing the more homogeneously mixed molten thermoplastic through the gate 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.
