AI-Powered supplier vetting

SummaryJinan Xinyu Cemented Carbide Co., Ltd. is identified as a Chinese manufacturer and factory established in 2009, with 68 employees, three production lines, and a 5,000 m² manufacturing plant. Its stated product range covers cemented carbide products for mining, drilling, geological prospecting, coal mining, construction engineering, and diamond production. The supplier reports export activity since 2013 and holds self-operated import and export rights, with exports representing 41%–50% of total sales. Production information includes carbide buttons, rods, shield cutters, stripes and blanks, and nozzles. The company states that it can process parts according to customer drawings and samples and uses specialized carbide manufacturing and inspection equipment. No certification records, after-sales service details, financial-credit evidence, or formal innovation metrics are provided. Two 2025 trade records associate the supplier with one Mexican buyer for drilling-related inserts, but the evidence is limited.

Supplier typeThe supplier is explicitly identified as a manufacturer, factory, and limited company located in Jinan, Shandong, China. Its stated business integrates R&D, manufacturing, and trade of cemented carbide products, indicating a direct production-oriented supplier rather than only a trading intermediary.

R&D capabilityThe company describes itself as integrating R&D with manufacturing and trade, and reports advanced cemented carbide production technology, manufacturing equipment, and detecting instruments. These statements support the existence of technical and development capabilities, but no quantified R&D investment, patents, new-product record, or formal innovation outcomes are provided.

Production capacityThe supplier reports 68 employees, three production lines, a 5,000 m² plant, 6–10 quality-control staff, and defined annual outputs for carbide buttons, nozzles, rods, shield cutters, stripes, and blanks. Its specialized equipment and broad carbide product range provide explicit evidence of established production capability.

Customization capabilityThe supplier explicitly states that it can produce and process parts according to customer drawings and samples. This directly supports customized manufacturing capability for customer-specific carbide parts.

Client casesTwo trade records from 2025 identify MCH MINING XPERIENCE S A DE C V in Mexico as an associated buyer for drilling-related inserts. These records provide a concrete customer reference, but they show only one named buyer and one transaction for each listed product, so the demonstrated customer base is limited.
