Sichuan Advance technology Co.,ltd(is dedicate to develop and manufacture co-rotation, counter-rotation parallel twin-screw extruder production line.We'll exhibit two types twin screw extruders, high torque(Nm/cm3>13).

We integrate and upgrade these experiences to create our own transmission concept and form our core technology “bilateral gear symmetrical driving system”. The technology enables our extruders have the advantages of “high torque, high efficiency, low energy-consumption, high price/performance ratio, long service life ” (designed service life of gearbox as long as 72000 hrs). We keep the same step with the most advanced extruder manufaturers in the world.

We can supply ：Co-rotation twin screw extruder production line;

High torque gearbox;Automatic long fiber reinforced thermoplastic composites (LFT - D) production line;Counter-rotation parallel twin screw extruder;Differential concentration mixer;

Repairing and machining large parts; Design, machine all of screw elements on Japan and Germany extruders.
