Product Description
Twin Screw Extruder Convey Screw Element, Compatible with 35/53/65/75/95/135 Barrel Sizes, Low Shear Material Conveying Block
Twin Screw Extruder Convey Screw Element
Brief Overview
Convey screw element is the core feeding component for co-rotating parallel twin screw extruders, installed on feeding, conveying and transition sections of extruder barrels. Designed with deep flute and wide spiral profile, it delivers ultra-low shear during material transportation, ensuring stable high throughput and preventing thermal degradation of sensitive plastics. The standard involute spline inner bore matches all series spline shafts, compatible with 35/53/65/75/95/135 twin screw extruder models.

Material & Wear-resistant Treatment
- Standard Nitrided Grade Made of 4140 alloy steel with integral nitriding surface hardening, cost-effective for general plastic compounding and pelletizing lines.
- Heavy-duty Bimetallic Grade Adopts bimetallic alloy or tungsten carbide overlay on working surface, specially customized for high-filled materials like glass fiber, calcium carbonate, greatly extending service life by 3–8 times.
Core Advantages
- Deep flute structure creates larger conveying volume, eliminates material stagnation dead zone and boosts production capacity.
- Low-shear geometric design, perfectly suited for biodegradable plastics, PVC, color masterbatch, food-grade polymer and heat-sensitive compounds.
- 5-axis CNC precision machining with mirror polishing surface, anti-adhesion and easy to clean.
- Universal involute spline bore, interchangeable spare parts for Coperion, Nanjing Keya, KraussMaffei and all domestic extruder brands.
- Abundant stock for standard sizes; custom drawing, non-standard processing and matched screw-barrel repair service available.
Application Scenarios
Plastic compounding pelletizing, biodegradable material extrusion, PVC mixing, color masterbatch production, high-filler masterbatch, cable material, food polymer extrusion production lines.
