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 tool box lock different from ordinary cabinet locks?

Our heavy-duty tool box lock features solid steel construction and a reinforced anti-pry structure for enhanced security and durability. With precision-engineered locking components and a wear-resistant surface finish, it offers far higher tamper resistance and longer service life than ordinary locks, maintaining stable performance even under frequent daily use.

Q:Is your tool box lock suitable for outdoor and harsh working environments?

Yes. It is coated with a heavy-duty protective finish that provides excellent waterproof, rustproof, and corrosion-resistant properties. It effectively withstands moisture, dust, mud, salt spray, and extreme temperatures, remaining reliable and durable for toolboxes installed on trucks, trailers, and outdoor work equipment.

Q:Will your tool box lock get stuck, rattle or produce abnormal noise during use?

No. The lock is designed with a smooth, precision-matched locking mechanism that ensures quiet and stable operation. It minimizes shaking and friction, eliminates rattling caused by vehicle vibration, and prevents jamming even during long-distance transportation and frequent opening and closing.

Q:Can your heavy-duty tool box lock be customized in size and style?

Yes, we provide complete OEM & ODM customization services. We can customize dimensions, lock body shape, mounting hole distance, surface treatment, lock cylinder type, and key system according to your requirements.

Q:How about the installation compatibility of your tool box lock?

Our tool box lock adopts a universal flush-mount design with standard pre-drilled mounting holes for simple and fast installation. It is highly compatible with most metal toolboxes, vehicle storage compartments, and truck side boxes, supporting direct replacement without complicated modification or extra processing.
