AI-Powered supplier vetting
SummaryThe supplier is a combined company with a broad hardware, metal structure, door and window, mold, mechanical component, plastic product, and furniture scope. It reports extensive customization, ODM and OEM capabilities, recent new-product development, and a substantial equipment base covering laser cutting, CNC bending, polishing, pipe cutting, punching, grinding, turning, hydraulic processing, and packaging. ISO9001:2015 and RoHS are reported, alongside documented service, corrective-action, and complaint-handling procedures. Inventory and overseas warehouse services are available, with stated lead times within 15 working days in both peak and off-season periods. However, there is no valid manufacturing contract with related subcontractors, no approved supplier list, no overseas showroom, no SDK, and no Fortune 500 customer collaboration. Financial information is insufficient for a reliable credibility assessment.
Supplier typeThe supplier is identified as a combined company and reports a broad business scope covering hardware products, metal structures, doors and windows, molds, mechanical components, plastics, furniture, and import/export activities. This indicates a diversified manufacturing and trading structure rather than a narrowly specialized supplier.
CertificationsThe supplier reports an ISO9001:2015 management-system certificate and RoHS product compliance certification. These explicitly support quality-management and product-compliance capabilities, although no other certifications are provided.
After-Sales capabilityThe supplier has written procedures and records for service assessment, corrective and preventive actions, and customer complaint handling. It also provides in-stock capability, overseas warehouse services, and stated lead times within 15 working days in both peak and off-season, but lacks an overseas showroom and has no valid manufacturing contract with related subcontractors.
R&D capabilityThe supplier reports new products during the past year, provides ODM services, and offers customization from samples, designs, and full or minor specifications. However, it explicitly has no available SDK, so the evidence supports product-development capability but not software-development integration.
Production capacityThe equipment list includes laser cutting, CNC bending and turning, automatic polishing, pipe cutting, punching, grinding, hydraulic processing, assembly, sealing, and manual and automatic packaging. Inventory capability, 15 qualified service suppliers, and lead times within 15 working days are also reported, while the absence of a valid manufacturing contract with related subcontractors is a documented limitation.
Customization capabilityBoth the R&D and design-capability records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier also reports ODM service availability, providing direct evidence of broad customization support.
