Gearboxes for Rubber and Plastic Machinery

SEPS Series Twin-screw Extruder Gearboxes

Based on NGC's advanced industrial gearbox platform, the SEPS series gearbox is a core component for twin-screw extruders. It features advanced technologies such as large width-to-diameter ratio gear multi-objective modification, dual output shaft phase near-zero difference technology, high-strength transmission shaft material modification and surface strengthening. It also features optimized structural topology and thermal power output, offering high load-bearing capacity, outstanding reliability, low vibration, and low temperature rise. The product is suitable for twin-screw extruders and widely used in the plastics, pharmaceutical, food, and petrochemical industries.
