AI-Powered supplier vetting
SummaryThe supplier manufactures centrifugal cast tubes and titanium products and reports more than 10 years of experience. It has integrated smelting, rolling, forging, cold drawing, and finish-machining production lines, 50 quality-control staff, and annual output in the stated US$10 million–US$50 million range. It reports ISO 9000/9001/14000/14001 and BSCI certifications. The supplier provides broad customization and ODM services, has introduced new products in the past year, and offers OEM services to known brands. Export sales account for 90%, with seven years of export experience and self-operated import/export rights. Complaint handling and corrective-action procedures are documented and followed. However, quality test equipment is reported as zero, traceability and quality-assurance status are unknown, and there is no overseas warehouse, showroom, agent, branch, or offline trade-show participation. Financial information is represented only by years, so financial strength cannot be verified.
Supplier typeThe supplier is a manufacturing company focused on centrifugal cast tubes and titanium products, with more than 10 years of experience and production capabilities covering smelting, hot and cold rolling, forging, cold drawing, and finish machining. Its 90% export-sales share, seven years of export experience, and self-operated import/export rights indicate an export-oriented industrial manufacturer.
CertificationsThe supplier reports BSCI, ISO 9000, ISO 9001, ISO 14000, and ISO 14001 certifications. These stated management-system and social-compliance certifications provide explicit evidence of certification coverage.
After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, and reports lead times within 15 workdays in both peak and off-season periods. However, it has no overseas agents or branches, overseas warehouse, showroom, or offline trade-show participation, limiting evidence of localized overseas support.
R&D capabilityThe supplier reports new products within the past year, ODM availability, broad R&D customization services, and R&D engineers with 6–10 years of total experience. It does not have an available SDK, but the supplied evidence supports product-development and design capability.
Production capacityThe supplier reports an integrated multi-process production system, 50 quality-control staff, inventory capability, 30 qualified service suppliers, and lead times within 15 workdays in both seasons. However, it reports zero quality-control test equipment, while quality assurance and traceability status are unknown; production scale is therefore supported, but testing controls are a material concern.

Client casesThe supplier reports providing OEM services to known brands, which is direct evidence of brand-customer experience. No specific customer names, project details, product volumes, or independently verifiable case information are provided.
