20mm twin screw laboratory extruder line for plastic compounding.
Special laboratory:
CHT20-Eco using integrated mode, all systems are installed on the main base, as long as
access to power and water can be put into use.
As the segment structure design, the equipment can be configured with different L/D, barrel designs,
screen changer, pelletizing system, and electric control, to flexible meet unique requirements of different process.In order to aid to our better understanding of the different material, the screw configuration is
designed which is based on rich experience and software technology to accomplish the material
conveying, plasticizing compounding, Shearing, dispersion and pressurization. Screw elements,
accurately designed with CNC technology, are fully intermeshed, providing self-cleaning and easy
interchangeability. We are upgrading accuracy and quality of high torque gear box. The special new type barrel structure and screw elements have been manufactured with our powerful design experience.
