Available screw diameters range from 15mm to 300mm with L/D ratios from 15:1 to 46:1, supporting applications from thin-film extrusion to heavy-duty compounding.
Base materials include 38CrMoAlA (JIS SACM645), 42CrMo (AISI 4140), 4Cr5MoSiV1 (JIS SKD-61), 9Cr18MoV, and proprietary HPT bimetallic alloys. Surface treatments include nitriding, hard-chrome plating, and bimetallic alloy welding, with nitrided layer depths of 0.5 - 0.8mm and hardness levels between 900 - 1000 HV. These specifications align with industry standards for wear resistance and corrosion protection in high-shear extrusion environments.
These components are used by manufacturers of pipes, sheets, filaments, and injection-molded parts requiring consistent melt homogeneity. Buyers typically specify screw type - barrier, separation, or gas-exhausting - based on polymer viscosity and degassing needs. The components are shipped coated with slushing oil and wrapped in film inside wooden cases to prevent corrosion during transit.

Before ordering, confirm the exact screw type - barrier, separation, or gas-exhausting - and match it to your polymer and output requirements. Request material certificates for the base alloy and surface treatment specs. Verify the L/D ratio and diameter tolerance against your extruder’s barrel bore. Do not assume compatibility with existing machinery without dimensional drawings.
Lead time is not stated and must be confirmed directly. Incoterms are not specified; negotiate FOB Ningbo or CIF destination. Payment terms are not listed - request a proforma invoice with T/T or L/C terms. Components are shipped in wooden cases with moisture barriers; confirm the packaging meets your port’s import requirements.
Upon receipt, inspect for surface scratches, corrosion, or coating damage. Use a profilometer to verify surface roughness and a hardness tester to validate nitrided layer values. Retain the original packaging for potential claims. Request a sample extrusion test if the screw is intended for critical applications, as performance varies with material and processing parameters.
