TDM Series Co-rotating Parallel Triple-screw Dynamic Compounding Extruder is a high performance patented polymer Continuous compounding equipment co-developed by Dekuma Welltec Machinery Co. Ltd and the National Engineering Research Center of Novel Equipment for Polymer Processing of South China University of Technology. With lower L/D radio of screw ,the machine achieves the mixing and blending effect which only can be achieved on the condition of large L/D radio twin screw extruder. With their unique features such as high filling, high dispersing, high output, and low energy consumption, this series of machines are widely applied to many polymer processing fields such as alloying, filling modification, mixing and dispersion of additives，reinforcement with fiber , reactive extrusion, polymerization and degassing of volatile components. TDM series co-rotating parallel triple-screw dynamic compounding extruder have gradually been accepted by twin screw users and will surely be one of the preferred equipments in the advanced plastics compounding filed.
