AI-Powered supplier vetting

SummaryJinjiang Sidebo Technology Industrial Co., Ltd. is identified as both a trading company and manufacturer/factory in China, with nearly 40 years of experience in stamping, welding, bending, plastic injection, and aluminum die casting. Its stated product range focuses on automotive engine and transmission components, supported by three production lines, 11–20 quality-control staff, and documented production quantities for several products. The company carries out TS 16949 quality controls across raw materials, production, and after-sales processes. It offers sample-, design-, flexible-, and minor-customization, but does not provide 3D software design, ODM, SDK, or overseas service infrastructure. No new products were reported in the past year. Formal service assessment, corrective-action, approved-supplier, and complaint-handling procedures are absent. Financial capacity data is listed for multiple years, but the slices provide no assessable financial results. Customer cases and named brand OEM evidence are...

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, is a limited company, and operates in Fujian, China. Its product scope is concentrated on oil pans, timing covers, oil pickups, dipsticks, and related automotive components.

CertificationsThe company states that TS 16949 is fully implemented across raw-material inspection, production processes, and after-sales activities. A CTI audit is also recorded for the period from 2026-04-10 to 2027-04-09, but the audit type and evaluation result of 0 are not explained sufficiently to establish an additional certification advantage.

After-Sales capabilityTS 16949 is stated to cover after-sales processes, but the supplier has no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. This is explicit evidence of a deficiency in documented after-sales management.

R&D capabilityThe supplier is identified as a professional technical supplier and has 6–10 years of total R&D-engineer experience, but it reported no new products in the past year and does not provide ODM, SDK, or 3D software design services. The evidence therefore shows some technical capability but a clear limitation in recent and software-related innovation services.

Production capacityThe supplier reports nearly 40 years focused on stamping, welding, bending, plastic injection, and aluminum die casting, operates three production lines, and has 11–20 quality-control staff. It also provides product-specific output quantities for engine oil pans, dipsticks, timing covers, transmission oil pans, and oil pickups, supporting an established automotive-component production capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, flexible customization, and minor customization. However, it does not provide 3D software design services, so customization is supported without evidence of advanced 3D design assistance.
