The conical twin screw barrel from Ningbo Cowell Industry Co., Ltd. is engineered for high-precision polymer processing, featuring screw diameters from 35mm to 200mm and lengths under 10000mm, matched by barrels of the same diameter range. It is machined from grades such as 38CrMoAlA, SKD61, SKD11, 40Cr, 42CrMo and other high-alloy steels, with surface treatments including nitriding, alloy coating spraying, heat-treatment and quenching to extend wear life in abrasive or high-temperature applications.
Material selection is tailored to the polymer: 38CrMoAlA and 42CrMo are typical choices for general-purpose resins, while SKD61 and SKD11 alloys are standard for processing engineering plastics like PA, EVA, EAA and PC where higher hardness and heat resistance are required. The conical design allows for consistent compression and melting of the polymer, reducing shear and improving output stability compared to parallel twin-screw configurations.
These barrels are used in extrusion lines for compounding, recycling and direct extrusion of thermoplastics, particularly where precise temperature control and uniform melt delivery are critical. Buyers in the plastic processing industry specify these components for applications such as profile extrusion, sheet production and masterbatch manufacturing. Sourcing terms, including MOQ, lead time and Incoterms, should be confirmed directly with Ningbo Cowell Industry Co., Ltd. to align with production schedules.

Sourcing Conical Twin Screw Barrel from Ningbo Cowell Industry Co., Ltd. - China Import Guide
Before ordering, verify the exact material grade and surface treatment specifications to ensure compatibility with your polymer and processing conditions. Request third-party inspection reports or mill certificates for critical components, as these confirm the mechanical properties and heat-treatment standards applied to the barrel and screw.
Confirm logistics details such as packaging, Incoterms (e.g., FOB Ningbo) and lead time, which can vary based on the supplier’s production schedule. For conical twin screw barrels, lead times may extend to 60-90 days for custom diameters or material grades, so plan accordingly to avoid production delays.
Quality checks should include dimensional inspection of the screw and barrel diameters, hardness testing of the treated surfaces and visual examination for defects such as cracks or improper coating. Request a pre-shipment inspection report and ensure the supplier provides a conformity certificate that includes the L/D ratio, material grade and surface roughness values.
