Feed Screws are precision-engineered components designed for consistent and efficient material feeding in twin-screw and single-screw extrusion systems. They ensure stable additive introduction, controlled flow, and enhanced process uniformity—playing a critical role in optimizing extrusion performance and product quality.
Feed screws uniformly introduce additives, enhancing mixing efficiency and quality. Widely applicable in plastic modification, rubber formulation, food processing, and chemical customization, meeting high uniformity and accuracy requirements. Optimize your production and enhance product quality.
Outer Diameter: φ15 mm ~ φ150 mm
Material: High-Torque Alloy Steel
Application: Twin-screw side feeders and extrusion systems
Standard: Compatible with major international extruder brands
Feature: High anti-wear performance and stable operation under continuous load
The side feeding screw is the core of the side feeder system, responsible for conveying and dosing secondary materials such as fillers, pigments, or modifiers into the main extrusion process.
Key Structural Features:
Screw Element Selection: Large-pitch conveying elements extend from the feed inlet to the adjacent closed barrel section, ensuring smooth transfer without material blockage.
Helix Direction: Right-hand threads maintain stable axial flow; optional left-hand sections help generate local back pressure when needed.
Precision Feeding: Designed to synchronize with the main screw for consistent material dosing and improved dispersion.
Feed screws are used in various extrusion and compounding processes, including:
Plastics Modification: Feeding masterbatches, flame retardants, or toughening agents for custom material properties.
Rubber Compounding: Adding fillers and functional additives to improve strength and abrasion resistance.
Food Processing: Controlled addition of ingredients such as antioxidants or anti-fog agents for improved texture and shelf life.
Chemical & Medical Materials: Precise dosing of active agents or functional powders to achieve consistent performance.
Stable feeding and high-accuracy additive control
Wear-resistant alloy steel construction for long service life
Optimized screw geometry for smooth conveying and efficient mixing
Compatible with major extruder brands worldwide
