Product Overview
ZHITIAN twin screw extruder screw elements are engineered for high-performance mixing, dispersion, and conveying in modern extrusion lines. Each element is CNC-machined with micron-level precision, ensuring excellent fit, torque transmission, and flow balance between elements.
Designed to meet the demands of plastic compounding, engineering polymer modification, and additive masterbatch production, these screw elements combine wear resistance, corrosion protection, and dimensional stability for consistent performance even under high-shear and high-temperature conditions.
