Our advantages
Performance level:same as German Flanders, Austria EssenBas, W&P, Berstorff and Leistritz,JSW,Toshiba；
High torque: up to 15Nm/cm3
High precision:bearings on output shaft 2 without load, the accuracy keep the same for a long time;
Long service life:up to 72000 hours (10 years);
High speed: max. 1750rpm/m;
High quality:small screw clearance reduce material reflux ,residence time in barrels and excessive shear;
High efficiency: with our gearbox, the output is 1-2 times larger than the same size low torque extruder ;
High allocation: brand of bearings are Sweden SKF and Germany INA; oil seals are imported from Germany.
