Its primary products are screw barrels and related extrusion, injection-molding, and rubber-processing components. The supplier reports ISO 9000 and ISO 9001 management-system certifications, more than 10 production lines, 6–10 quality-control staff, and 6–10 years of total R&D-engineer experience. It exports through agents and its own import-export rights, serving multiple regions. The supplier also describes a large production area, over 400 workers, more than 300 pieces of equipment, and customized services. However, the provided information does not establish current after-sales service capability, innovation outputs, financial credibility, or documented customer cases. The SGS audit record is time-limited and shows an evaluation result of 0, but the meaning of that result is not defined in the provided data.

Supplier typeThe supplier is identified as a trading company in the company basic information, while another record classifies it as a Trading Company, Manufacturer/Factory, and Group Corporation. Its products and manufacturing-machinery trade engagement are specifically related to screw barrels and associated components. This supports classifying it as a trading and manufacturing-oriented supplier, although the records are not fully consistent regarding the principal entity type.

CertificationsThe supplier reports ISO 9000 and ISO 9001 management-system certifications. An SGS audit record is also provided, with a stated report period from August 5, 2024 to August 4, 2025; however, the audit result is recorded as 0 and its interpretation is not explained. The certifications provide explicit positive evidence, but current validity beyond the stated audit period is not established.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, a factory in Zhoushan, and primary export markets across several regions. Its company description additionally states a production area of up to 40,000 square meters, more than 400 full-time workers, and over 300 domestic and imported equipment units. These stated facilities, workforce, equipment, and production-line indicators provide explicit evidence of substantial production capability.

Customization capabilityThe product range includes multiple screw-barrel configurations, including twin-screw, extrusion, injection-molding, rubber, bimetallic, and single-screw products, as well as screw elements and feed-housing barrels. The supplier also explicitly advertises customized VIP services. This directly supports an ability to provide customized product solutions, although the scope and technical limits of customization are not specified.
