AI-Powered supplier vetting
SummaryThe supplier operates in oil drilling, workover, cementing, completion, mining machinery, and related technical services. It has documented production equipment, quality-control procedures, product traceability, complaint-handling procedures, and customization options ranging from sample-based work to full customization. The supplier reports recent new-product development and ODM services, but is not identified as a professional technical supplier and does not provide 3D software design or SDK services. It holds ISO9001:2015, ISO45001:2018, ISO14001, and other certifications. Financial records are identified for 2020–2022, but their contents are not provided. Overseas warehouse, showroom, agent, or branch capabilities are absent. No specific customer cases are disclosed.
Supplier typeThe supplier is explicitly not classified as a professional technical supplier, while its stated business scope covers production, R&D, sales, maintenance, leasing, and technical services for oil drilling, workover, cementing, completion, and mining equipment. This indicates an equipment-focused industrial supplier with related technical-service activities rather than a dedicated professional technical-services provider.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, and other certifications. These certifications provide explicit evidence of quality, occupational health and safety, and environmental management certification.
After-Sales capabilityThe business scope includes maintenance and technical services, and the supplier has a clear, followed procedure for handling customer complaints. However, it has no overseas warehouse, showroom, overseas agent, or overseas branch, so international service coverage is limited based on the available evidence.
R&D capabilityThe supplier reports new products within the past year and provides ODM services, indicating active product-development capability. However, it does not provide 3D software design services, has no available SDK, and is explicitly not classified as a professional technical supplier, which limits the demonstrated scope of innovation support.
Production capacityThe supplier has a broad equipment base including tempering, carburizing and nitriding furnaces, lathes, milling and boring machines, CNC machining centers, and impact-testing equipment. Finished-product inspection instructions are uniformly followed, and the supplier reports 20 years of export experience with 41%–50% of sales from exports.
Customization capabilityBoth records explicitly list customization from samples, customization from designs, minor customization, and full customization. This demonstrates a broad stated customization range covering limited modifications through fully customized products.
