● specially designed chromium plated screw& barrel is suitable for pvc, upvc. cpvc. powder pvc. with which can stabilize pvc material temperature, stable injection molding and create high plasticizing rate.
● high-torsion/low- rotation hydraulic motor increases effi cient plasticized capacity, reduces cooling time and lowers material consumption.
● specially designed widened safety door especially for the pvc moulds with big oil cylinder, easy for mold installation and more safety for the operator.
● two groups of core-pulling, two in and two out of each group.
● equipped with fans and wind cover, ensure minimum material temperature deviation.
● multiple groups of core-pulling and stainless steel screw are for option.
