1) The main parts, such as screw, barrel, adopt superior 38CrMoAIA material, which is featured by high hardness, anticorrosive advantages

2) The special designed screw adopts big L/D Ratio to ensure the good plasticizing, stable extrusion and high output.

3) Screen Exchanger: It adopts hydraulic style fast screen exchange with double filters.
4) Hard Teeth Gearbox: The body of the gearbox is made from cast steel. The teeth deal with grinding and peeling eventually, which provides different characteristics of damping, antifriction, low-noise, long using period etc.
5) T-die: Super heat resistance steel alloy. Heating inside by bar heaters. The outlet of the mould could be adjusted with screw slightly.
