AI-Powered supplier vetting

SummaryThe supplier is a China-based manufacturer of metal chains, metal products, molds, automotive parts, and related products, with nearly 20 years of stated experience and 12 years of export activity. It reports TS 16949 certification, one production line, five R&D engineers, recent new-product launches, OEM service for well-known brands, and ODM capability. Customization is broad, covering designs, samples, full customization, flexible customization, and minor customization. Quality and service procedures are documented and followed, including finished-product inspection, corrective and preventive actions, complaint handling, and supplier assessment. The supplier has manufacturing-capacity contracts with associated subcontractors and in-stock capability, but no overseas warehouses, showrooms, agents, or branches. Evidence of customer cases is limited: it reports no Fortune 500 cooperation but does report OEM work for well-known brands and a repeat-buyer preference range.

Supplier typeThe supplier is identified as Huangyan Xinqian Yingjia Metal Product Factory, a manufacturer based in Huangyan District, Taizhou, Zhejiang, China. Its stated business scope covers metal chains and other metal products, metal materials, molds, automotive parts and accessories, and related sales activities, indicating a manufacturing-oriented supplier rather than a pure trading company.

CertificationsThe supplier reports holding TS 16949 certification and also lists another management-system certification category as "Others." This provides explicit evidence of at least one relevant certified management system, although the details and scope of the additional certification are not provided.

After-Sales capabilityThe supplier reports documented and followed procedures for corrective and preventive actions and customer complaint handling, along with quality assurance in its quality-control processes. However, it has no overseas warehouse, showroom, agent, or branch, so local overseas support infrastructure is not evidenced.

R&D capabilityThe supplier reports five R&D engineers, new products launched during the last year, product-information output from R&D, and ODM service availability. These are explicit indicators of active product development, although no SDK is available and no quantitative product-development performance beyond the stated information is provided.

Production capacityThe supplier operates one production line, has manufacturing-capacity contracts with each associated subcontractor, and reports in-stock capability. It also states an average peak-season lead time of one month and an off-season lead time within 15 workdays, supported by written supplier-service assessment procedures and 20 qualified suppliers. These data support operational capability, while the single-line count limits evidence of production scale.

Customization capabilityThe supplier explicitly provides customization from designs, customization from samples, full customization, flexible customization, and minor customization. The same range is linked to its R&D capability, and ODM service is available, demonstrating broad product-development and customization support.

Product Q&A

Q:What is the exact size of the mounting holes and the hole center distance?

Please refer to the detailed technical drawing in our product images. It clearly marks the hole diameter, the distance between the two mounting centers, and the overall wheel dimensions. We strongly recommend measuring your existing bracket or track before ordering to ensure a perfect match for replacement.

Q:Is this sliding roller suitable for heavy-duty cargo tracks and side curtains?

Yes, absolutely. This pulley assembly is specifically engineered for commercial vehicles and industrial tracks. The solid steel wheel and reinforced mounting bracket are designed to withstand continuous heavy loads, making it an ideal choice for truck cargo box doors, trailer curtain systems, and heavy sliding panels.

Q:Does the roller wheel have built-in ball bearings for smooth operation?

Yes. The precision-machined metal wheel is equipped with high-quality internal bearings. This design ensures very smooth, quiet, and low-friction sliding movement along the guide rail, preventing jamming and reducing wear even under heavy daily usage.

Q:What material is used for this pulley, and is it resistant to rust?

It is manufactured from high-strength steel with a professional anti-corrosion galvanized finish. This protective coating provides excellent defense against moisture, rain, and road salt, ensuring reliable, rust-free performance even in harsh outdoor logistics environments.

Q:Do you offer custom sizes or OEM manufacturing for this sliding roller?

Yes, we do. As a professional hardware manufacturer, we warmly welcome OEM and ODM orders. We can adjust the bracket length, hole spacing, wheel diameter, and surface finish according to your specific technical drawings or sample requirements. Please contact our sales team for a customized quotation.
