Impact properties and microhardness of double-gated glass-reinforced polypropylene injection moldings

Injection moldings with weld lines were produced in glass reinforced polypropylene grades differing in filler content using a two‐gated hot runner injection mold. The skin‐core microstructure developed during injection molding was qualitatively analyzed by means of optical and scanning electronic mi...
