AI-Powered supplier vetting

SummaryThe supplier demonstrates professional technical and R&D capabilities, including 3D software design, ODM/OEM services, broad customization, and specialized testing and production equipment. Its business scope covers metal products, construction fittings, hardware, metal structures, and rubber products. Quality-related evidence is positive: ISO9001 certification, quality assurance, traceability, and documented corrective-action and complaint procedures. The supplier reports inventory capacity, qualified service-capable suppliers, and one-month lead times in both peak and off-season periods. However, it lacks a valid manufacturing-capacity contract with associated subcontractors, overseas warehouses, overseas showrooms, overseas agents or branches, and offline trade-show participation. Innovation evidence is mixed because no new product was reported in the past year and no SDK is available, although patents and university cooperation are stated. Financial credibility cannot be determined from the provided...

Supplier typeThe supplier identifies as a professional technical supplier and operates across R&D and manufacturing of metal products, construction fittings, hardware, metal structures, and rubber products. This supports classification as a technical manufacturer with a broad industrial product scope.

CertificationsThe company description states that the supplier is ISO9001 certified and holds more than 100 national patents. ISO9001 is explicit evidence of certification, although no additional certification details are provided.

After-Sales capabilityThe supplier has documented procedures and followed records for corrective and preventive actions and customer complaint handling. This is direct evidence of an established service-response mechanism, while no specific response times or warranty terms are stated.

R&D capabilityThe supplier provides R&D, 3D software design, ODM, and OEM services, and reports more than 100 national patents plus university cooperation on seismic isolation technology. However, it reported no new products in the past year and has no available SDK, so the evidence supports technical innovation capacity but not all forms of product or software innovation.

Production capacityProduction evidence includes broad manufacturing business scope, specialized testing and production equipment, inventory capacity, 17 qualified suppliers for service capability, and stated one-month lead times in both peak and off-season. A limitation is that no valid manufacturing-capacity contract exists with associated subcontractors, which creates a documented capacity-governance weakness but does not negate the stated in-house capability evidence.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, supported by 3D software design services and listed design and production equipment. This is clear evidence of broad customization capability.

Client casesThe supplier states that it is qualified to cooperate with China Communications Construction, CSCEC, and China Railway, and that it provides OEM services for popular brands. These statements indicate experience or qualification involving major customers, although no project details, order scope, or verifiable case outcomes are provided.

Product Q&A

Q:what is his structure

The whole bearing consists of three parts: internal laminated core, upper & lower connecting flange plates and outer protective rubber cover.

Q:what is laminated core?

Alternating layers of thin natural rubber sheets and highstrength steel plates are integrally vulcanized and bonded under high temperature ,140 to 160 centigrade and high pressure via a plate vulcanizer, with no delamination gaps. Steel plates: 2 to 5 mm thick, restricting lateral expansion of rubber and providing high vertical bearing stiffness; Natural rubber layers: single layer thickness 5 to 15 mm, offering horizontal flexible deformation and elastic selfcentering capacity.

Q:what is its application scenarios?

Civil Buildings (Main Application Scenarios) Special Projects Museums, precision instrument workshops and data centers, to protect valuable equipment from seismic impact; Seismic isolation for small municipal overpasses and low-rise bridge foundations.

Q:Disadvantage

It has extremely low inherent damping and cannot be used independently. The isolation layer must be equipped with VFD viscous dampers; the displacement of the isolation layer will be relatively large under strong earthquakes.
