Extruder Screw Barrel
The Extruder Screw Barrel from Zhoushan Qunying Plastic Machinery Manufactory is a precision component designed for single-screw extrusion systems used in thermoplastic processing. It is compatible with standard extruder models from 30mm to 120mm barrel diameter, with L/D ratios typically ranging from 20:1 to 30:1. The barrel inner surface is hardened to HRC 58-62, and the screw flight clearance is maintained within 0.05mm to 0.15mm to ensure uniform melt flow and minimal material degradation.
The barrel is manufactured from 38CrMoAlA alloy steel, a standard grade in extrusion equipment for its nitriding response and wear resistance. The screw component, when paired, uses the same alloy with a nitrogen-hardened surface layer. These materials are typical in industrial-grade extruders handling polyolefins, PVC, and ABS. The component does not include coatings such as bimetallic or stellite, and no surface treatment beyond standard nitriding is confirmed by the supplier.
This screw barrel is used primarily in pelletizing, film extrusion, and pipe production lines across Southeast Asia and Eastern Europe. Buyers include medium-scale plastic processors and OEM equipment assemblers. Trade terms include FOB Zhoushan Port, with packaging in wooden crates and standard lead times of 30 to 45 days after deposit. MOQ is one unit, and payment is typically 30% advance with balance against shipping documents.
| Barrel Material | 38CrMoAlA alloy steel |
| Surface Hardness | HRC 58-62 (nitrided) |
| Barrel Diameter Range | 30mm to 120mm |
| L/D Ratio | 20:1 to 30:1 (typical for general-purpose extrusion) |
| Screw Flight Clearance | 0.05mm to 0.15mm |
| Barrel Length Tolerance | ±0.5mm (standard for industrial extrusion barrels) |
| Internal Surface Finish | Ra ≤ 0.4μm (typical for polymer processing) |
| Cooling Channels | Integrated water jackets, standard spacing of 15mm |
| Flange Type | ISO 11577-1 compliant (typical for European and Asian extruder systems) |
| Packaging | Wooden crate with rust inhibitor and foam padding |

Sourcing Extruder Screw Barrel from Zhoushan Qunying Plastic Machinery Manufactory - China Import Guide
Before ordering, verify the exact barrel diameter, L/D ratio, and flange type match your extruder model. Confirm the material grade is 38CrMoAlA and request a heat treatment certificate showing nitriding depth and hardness profile. Do not rely on marketing terms like 'quality' - demand documented metallurgical data. Ensure the supplier provides a packing list and inspection report before shipment.
Confirm Incoterms are FOB Zhoushan Port, and clarify who arranges export documentation and marine insurance. Lead time is typically 30 to 45 days, but confirm production scheduling in writing. Payment terms are usually 30% advance, 70% against copy of bill of lading. Request a tracking number and container sealing protocol if shipping full container load.
Inspect the barrel upon arrival for surface scratches, corrosion, or deformation. Verify internal roughness with a profilometer and check clearance using feeler gauges. Request a copy of the production test log for pressure and leak tests. Ensure the crate contains a serial number tag matching the invoice. Retain all packaging until 30 days after installation to support warranty claims, if any.
