AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier specializing in cooling-tower products, including reinforced-concrete, all-steel, air-conditioning, energy-saving, and water-saving cooling towers. It offers 3D design, OEM, ODM, and multiple customization options, and reports new-product development during the past year. Quality processes include documented inspection instructions, quality assurance, material traceability, and recorded corrective and preventive actions. Manufacturing contracts with associated subcontractors and in-stock capability are reported. The supplier lacks SDK availability, overseas warehouses, overseas showrooms, overseas agents or branches, and offline trade-show participation. Exporting began two years ago, with 41%–50% of sales from exports. Certification information includes ISO 9001:2015, ISO 45001:2018, and ISO 14001, while financial data is insufficient for a credibility judgment.
Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and describes products centered on multiple types of cooling towers. Its stated cooperation with universities and research institutions further supports a technology-oriented manufacturing profile.
CertificationsThe supplier reports ISO 9001:2015, ISO 45001:2018, and ISO 14001 certifications, along with an additional unspecified certification category. These stated certifications support its quality, occupational-safety, and environmental management credentials.
After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints. It also reports quality assurance and traceable identification of raw materials, providing explicit evidence of structured post-delivery issue handling.
R&D capabilityThe supplier provides 3D software design, reports new products during the past year, offers ODM services, and describes a strong R&D team with university and research-institution cooperation. However, it explicitly lacks an available SDK, which limits the scope of its disclosed technical-development capability.
Production capacityThe supplier reports valid manufacturing contracts with each associated subcontractor, in-stock capability, written and uniformly followed finished-product inspection instructions, and one-month average lead times in both peak and off-season periods. These statements provide positive evidence of organized production and fulfillment capability, although overseas warehouse and overseas service infrastructure are absent.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, together with 3D design, ODM, and OEM services. This indicates broad product-development and customization coverage.
Client casesThe supplier states that it provides OEM services for well-known brands and that 41%–50% of total sales come from exports, with exporting beginning two years ago. These claims indicate some brand and international-business experience, but no specific customer names, project details, or verifiable case descriptions are provided.
