Extruder Screw Barrel
This extruder screw barrel is designed for plastic extrusion systems with a bore diameter range of 35mm to 200mm and lengths up to 10,000mm, as stated in the supplier's data. It is manufactured from alloy steels including 38CrMoAlA, SKD61, SKD11, and 40Cr, selected for thermal stability and wear resistance under high-pressure polymer flow. The barrel is precision-machined to ensure concentricity and thermal expansion compatibility with the screw.
The material grades listed are industry-standard for screw barrels: 38CrMoAlA is used for general-purpose applications, SKD61 for high-temperature zones, SKD11 for abrasive material handling, and 40Cr for cost-effective medium-duty use. Surface treatments such as nitriding or bimetallic lining are not specified, so the barrel likely relies on base material hardness alone. Internal surface finish is not stated but should be ≤Ra 0.4 μm for optimal flow.
These barrels are used in packaging, automotive, and consumer goods manufacturing for extruding films, profiles, and pellets. Buyers should match the barrel's length-to-diameter ratio to their screw design. Trade terms include FOB and CIF, but MOQ and lead time are not provided. Buyers must confirm thermal expansion coefficients and cooling channel configuration before installation.

Sourcing Extruder Screw Barrel from Ningbo Cowell Industry Co., Ltd. - China Import Guide
Verify the barrel's material grade, bore diameter, and length against your extruder's specifications before ordering. Request a material certificate for each alloy used (e.g., EN 10083 for 38CrMoAlA). Confirm that the internal surface finish meets Ra ≤ 0.4 μm and that cooling channels are properly aligned with your heater bands.
Lead time and Incoterms are not stated. Buyers must confirm whether the barrel is shipped FOB Ningbo or CIF destination, and whether payment is via T/T or L/C. Packaging must include internal moisture barriers and rigid steel crating to prevent damage during long sea voyages. Confirm the barrel's weight and dimensions for freight planning.
Upon receipt, perform a visual inspection for surface damage and verify dimensions with calipers. Conduct a thermal cycle test to check for warping or stress cracks. Retain a sample of the barrel's material tag for traceability. Always request a quality control certificate and NDT report before commissioning the barrel in production.
