It is a conical screw barrel designed for plastic processing machines, manufactured by Zhoushan Dinghai Jinmao Plastifying Machinery Manufacturing Factory in China. It is forged from alloy steel grades 38CrMoAIA (JIS SACM 645) and 9Cr18MoV, and receives a nitrided surface with hardness between HV900 and HV1000. The barrel geometry follows a conical profile to promote efficient melt flow and mixing. The component is supplied as a finished part ready for installation.
The selected steels offer high tensile strength and corrosion resistance suitable for temperatures up to 500 °C common in extrusion and injection molding. Nitriding creates a wear‑resistant layer that extends service life compared with untreated barrels. In the plastics industry, conical barrels of similar composition are standard for high‑capacity lines. Typical barrels of this class have a length of 1200 mm, an outer diameter of 250 mm, and a pressure rating of 2 MPa, though exact dimensions should be confirmed with the supplier.
This barrel is used in extrusion and injection molding machines that process engineering polymers such as polycarbonate or nylon. Plant engineers and equipment integrators source it to improve throughput and product consistency. Suppliers usually offer FOB or CIF terms, and MOQ is negotiated per order; interested buyers should request detailed packaging and shipping options from the factory.

Before placing an order, verify the exact alloy grades, nitrided hardness, and dimensional drawings. Request a material test report and, if available, a certificate of compliance with relevant industry standards. Confirm that the barrel’s pressure rating and operating temperature match your machine’s requirements to avoid mismatches during installation.
Logistics should be aligned with agreed Incoterms such as FOB or CIF; discuss container size, loading method and any special handling needs. Lead time is not disclosed in the listing, so ask the supplier for a production schedule and expected dispatch date. Payment terms are typically negotiated per transaction - common options include TT or L/C, but confirm the preferred method before signing a contract.
Arrange a pre‑shipment inspection that includes hardness measurement, dimensional verification and visual checks for surface defects. If your company requires third‑party certification, request an independent inspection report. Ensure that packing lists, commercial invoices and any required export documentation are prepared in accordance with Chinese export regulations and the import requirements of your destination country.
