AI-Powered supplier vetting
SummaryThe supplier is a professional spring and mould-accessory manufacturer with 14 years of development and stated production and testing equipment. It offers extensive customization and 3D software design services. However, its quality and service systems have documentation gaps: finished-product inspections and corrective-action procedures lack written records, and material traceability is absent. No supplier-management certification or environmental impact assessment report is stated. The supplier has no in-stock capability, overseas warehouse, overseas branch or agent, or overseas showroom. Financial information is represented only by years, without usable performance details. International market coverage is claimed, but no customer cases are specifically identified.
Supplier typeThe supplier identifies itself as a manufacturer of die, compression, extension, torsion, disc, gas, and leaf springs, as well as mould accessories. Its stated 14-year development history and factory production/test lines support classification as a specialized manufacturing supplier.
CertificationsSupplier-management-system certification is explicitly listed as NIL. The supplier states that it has quality assurance, but it lacks an environmental impact assessment report and does not provide evidence of formal certification.
After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records. It also lacks inventory, overseas warehouses, overseas branches or agents, and overseas showrooms, limiting documented and local after-sales support.
R&D capabilityThe supplier is identified as a professional technical supplier and provides 3D software design services with flexible customization. However, it has no available SDK, so the evidence supports design capability but not broader software-integration innovation.
Production capacityThe factory reports a complete production and testing line, including heat treatment, automatic spring coilers, CNC end-face grinders, shot blasting, wire cutting, welding, polishing, and other equipment. It also reports two quality inspectors, but has no inventory capability and no valid manufacturing-capacity contract with related subcontractors; the stated weekly capacity is incomplete, preventing assessment of output volume.
Customization capabilityThe supplier explicitly offers customization from samples, designs, minor customization, full customization, and flexible customization, supported by 3D software design services. The same customization scope is reported for both R&D/design and production-related capability.
