    Frequently Asked Questions (FAQ)
    What is the output capacity of the CJWS75 Twin-Screw Extruder?
    The CJWS75 Twin-Screw Extruder offers an output capacity of 1–2 T/h, powered by a 450 kW AC frequency motor with a maximum screw speed of up to 900 RPM, making it highly energy-efficient and suitable for large-scale production of engineering plastics compounds.
    How does the glass fiber reinforced side feeder protect fiber length?
    The side feeder uses a low-shear feeding design that introduces glass fibers into the main material flow in a controlled, sectional manner. This approach preserves fiber length — especially long fibers of 6–25 mm — minimizes fiber breakage, prevents agglomeration, and improves dispersion uniformity within the polymer matrix.
