Reciprocating extruder
Main features of the TDW extruders
Thanks to complicated motions inside the extrusion systems, including the rotating mottion and reciprocating motion, TDW extruders show some unique features. The uniform shearing effect between the pins and filghts is generated in the gap between the screw filghts and barrel pins. Consequently, the materials experience the process of relaxing-shearing-relaxing circulation, that contributes to the best dispersion mixing and avoid the overheat of compounds. Meantime, the fight sections divide the flow with numerous times to get very good distributive mixing.
Modular design of screw elements and barrels could be convenient to adapt many different purposes. Even shorter L/D with 4 flights will greatly increase the mixing strength and also the pumping capacity.
Sucessful applications
Unique working principles of TDW extruders and resuliting mixing effects feature the sucessful applications to some special materials and special process technoligies.
