A leading Chinese automotive door panel producer has been using PP resin to conduct injection machine barrel and mold hot runners color switch for years. In 2019, the company introduced a Japanese branded purging compound, which partially shortened the purging cycle but still suffering from higher dosage and thus higher cost.

The trial run of PlasE Clean purging compound (PC) was conducted at a 1600T clamping force injection machine with 5 hot runner nozzles.
