    Frequently Asked Questions (FAQ)

    Q What is the maximum output capacity of the CJWS75 Twin-Screw Extruder?
    The CJWS75 Twin-Screw Extruder delivers an output capacity of 1–2 tons per hour, powered by a 450 kW AC frequency motor with a maximum screw speed of 900 RPM, making it suitable for high-volume engineering plastics compounding production.
    Q How does the glass fiber side feeder preserve fiber length during processing?
    The side feeder employs a low-shear feeding design that introduces glass fibers (6–25 mm long fibers) into the main material flow in a controlled, sectional manner. This minimizes mechanical damage to the fibers, preserves their length, prevents agglomeration, and ensures uniform dispersion throughout the matrix.
    Q What materials are the barrel and screw elements made of, and why does it matter?
    The barrel is fitted with integral tungsten carbide alloy liners for exceptional wear resistance, while the screw elements are manufactured from powder metallurgy (PM) materials. This combination ensures long service life, reduced maintenance costs, and stable performance even when processing highly abrasive or corrosive engineering plastics.
    Q Which industries are best suited for engineering plastics produced by this compounding line?
    This compounding line is widely used across automotive, electrical & electronics, mechanical engineering, aerospace, medical devices, energy & environmental protection, and emerging sectors such as 3D printing and 5G communications.
