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 makes your commercial vehicle door lock different from ordinary locks?

Our door lock is forged from heavy-duty thickened alloy steel with an integrated molding process, featuring enhanced anti-pry and anti-drilling structures. It boasts higher load-bearing and tamper-resistant capacity, not easy to deform or break under long-term heavy use and forced entry attempts.

Q:Is your door lock suitable for harsh outdoor and logistics working environments?

Absolutely. We adopt high-standard hot-dip galvanizing and anti-corrosion coating treatment, which is waterproof, rust-proof, and salt-spray resistant. It adapts to rain, snow, high humidity, and coastal conditions, ensuring a long service life even in extreme climates.

Q:Will your vehicle door lock jam or make abnormal noise during operation?

We integrate a precision lubrication guide structure and wear-resistant bushing design. The lock operates smoothly with no jamming or abnormal noise, reducing daily friction and extending the maintenance cycle for reliable long-term use.

Q:Can your heavy-duty lock support customized sizes and styles?

Yes. We support OEM & ODM customization, including different hole spacing, locking methods, surface treatments, and handle styles. It can perfectly match various box trucks, semi-trailers, refrigerated vans, and cargo containers.

Q:How about the installation compatibility of your commercial vehicle door lock?

Our lock is designed according to international general mounting standards, with a simple and fast installation process. It is interchangeable with most mainstream commercial vehicle door accessories, saving your time for replacement and assembly.
