The specific torque density reaches 15 Nm/cm³, with a maximum screw speed of 900 rpm. The compact structure enables low noise levels (≤80 dB(A)), and the transmission efficiency is ≥95%. The barrel features a nickel-based powder alloy sintered liner, which is wear- and corrosion-resistant and patent-pending. The new spiral cooling channel enhances cooling efficiency and minimizes deformation. For temperature control, it is equipped with an imported CO-AX coaxial valve, while heating is provided by an imported heating rod, ensuring high efficiency and long service life. The screw elements are made of hot isostatic pressed (HIP) material, offering 2-3 times the wear and corrosion resistance compared to domestic materials. The screw shaft is constructed from high-strength, high-toughness imported alloy steel, delivering excellent mechanical properties.With an optimized overall design, the system enhances transmission efficiency and operational stability.
