Sichuan Hexin Machinery Manufacturing Co., Ltd. is a specialized manufacturer of extruder spare parts based in the Dujiangyan Economic Development Zone, Sichuan, China.
We focus on the precision components at the heart of twin-screw, triple-screw and multi-screw extruders: screw elements, kneading blocks, core shafts, wear-resistant liners and barrels.
