AI-Powered supplier vetting

SummaryChangsha Sollroc Engineering Equipments Co., Ltd. is identified as both a trading company and manufacturer/factory in China, supplying mechanical, specialized equipment and concrete additives. It reports production capacities for DTH and RC products, flexible customization, broad export-market coverage, and participation in the BAUMA trade show. However, the available information shows no inventory, overseas warehouse, showroom, agent or branch capability, and no overseas service countries. Service-capability assessment, approved-supplier management, corrective actions and complaint handling lack written procedures or records. R&D resources are limited to one engineer, with no new products launched in the past year, no ODM, branded OEM or SDK capability, and no quality-control test equipment reported. Raw-material traceability, quality assurance, environmental assessment and fire-drill status are unknown. Financial records are indicated for recent years, but the slices do not provide sufficient...

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, with a limited-company structure in China. Its stated business scope covers sales of general and specialized mechanical equipment, concrete additives, electromechanical products, non-ferrous metals, and instruments and meters.

After-Sales capabilityThe supplier reports one-month average lead times in both peak and off-season and accepts multiple quotation and payment terms, but it has no inventory, overseas warehouse, showroom, agent or branch capability and reports zero overseas service countries. Service-capability procedures, approved-supplier records, corrective-action records, and customer-complaint procedures are absent, indicating insufficient evidence of a controlled after-sales system.

R&D capabilityThe supplier has one R&D engineer whose stated responsibility is Technical Service, but launched no new products in the past year and does not provide ODM, branded OEM or SDK services. The evidence indicates limited documented innovation capability.

Production capacityReported annual capacities are 20,000 DTH hammers, 100,000 DTH bits, 10,000 RC hammers and 200,000 RC bits, with 11–20 quality-control staff and export coverage across multiple regions. However, the supplier reports zero quality-control test equipment, so production volume is evidenced but quality-control infrastructure is a clear weakness.

Customization capabilityThe supplier explicitly states that it provides flexible customization design services. This is direct evidence of customization capability, although no scope, process or example is provided.
