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.
