High-Precision 2 to 3 Flighted Transfer Elements for CTE Extruders | Direct Factory
Wear-Resistant 2-Flighted to 3-Flighted Transition Elements for CTE Extruders
Product Overview
In high-throughput plastic compounding, transferring polymer melt between two-flighted (high conveying capacity) and three-flighted (high shear and tight dispersion) processing zones often causes severe pressure fluctuations, excessive melt temperatures, and material stagnation.
CONLIN’s Flighted Transfer Screw Elements are engineered specifically for CTE twin-screw extruders to bridge this geometry gap. By utilizing a CNC-ground transition contour that shifts gradually from a 2-lobe cross-section to a 3-lobe cross-section, these elements maintain continuous volumetric displacement while balancing shear input. Furthermore, this design prevents thermal degradation of sensitive resins, leading to stable head pressure and uniform pellet quality.

Key Advantages
-
Seamless Geometry Transition: Gradually shifts melt from 2-flight to 3-flight zones, which eliminates dead zones and stops resin degradation.
-
Effective Pressure Balancing: Reduces pressure surges between barrel sections; consequently, drive torque remains stable under high feed rates.
-
Controlled Shear Input: Lowers frictional heat accumulation, meaning thermal-sensitive polymers maintain their physical properties.
-
Direct Drop-in Replacement: Precision spline-hobbed bore guarantees exact slide-on fit onto CTE factory splined shafts without manual modification.
-
Extended Service Life: Manufactured using vacuum heat-treated alloys that resist severe abrasive wear from glass fibers and mineral fillers.
Product Applications
-
Color Masterbatch Processing: Prevents pigment buildup and enables quick color changes without cross-contamination.
-
Engineering Plastics Compounding: Ideal for compounding PA6, PA66, PBT, PET, and PC loaded with up to 50% glass fibers.
-
Flame Retardant Formulations: Smooths out melt passage for halogen-free flame retardant compounds that are sensitive to excessive shear.
-

FAQ
Q: Why use a 2-flighted to 3-flighted transfer element instead of standard conveying elements?
A: Standard conveying elements create abrupt geometrical changes when moving resin into high-shear 3-flighted zones. In contrast, transfer elements gradually transition the flight profile, which prevents pressure spikes, reduces melt temperature, and stops polymer burning.
Q: Are these transfer elements fully compatible with original CTE extruder shafts?
A: Yes. We manufacture these elements to precise CTE spline and flight tolerances. As a result, they slide directly onto original CTE shafts with accurate shaft-to-element clearances.
Q: Which material should I choose for processing glass-filled PA66?
A: For high glass-fiber loads (30% to 50%), we recommend powder metallurgy (PM) HIP sintered alloys (such as WR13 or CPM 10V). These alloys provide deep wear resistance and last significantly longer than standard M2 high-speed steel.
