AI-Powered supplier vetting

SummaryThe supplier is a 26-employee manufacturing factory in Zhangjiagang, Suzhou, producing PDC and tricone bits. It provides OEM services for well-known brands, ODM services, and broad customization based on samples or designs. R&D uses AutoCAD, Pro/E, and SolidWorks, and the supplier reports new products within the past year; however, it lacks available SDKs and auditable R&D design documentation. Quality-related procedures and records are reported for corrective actions, complaint handling, supplier-service assessment, and finished-product inspection, with one quality inspector identified. Service strengths include stocked products, participation in the OCT offline trade show, and stated peak- and off-season lead times within 15 working days. Limitations include no valid manufacturing contract with related subcontractors, no overseas warehouse, showroom, agent, or branch, and zero stated countries served overseas. Financial information is insufficient for a credibility judgment.

Supplier typeThe supplier is explicitly identified as a factory and limited company in the manufacturing industry, located in Zhangjiagang, Suzhou, with 26 employees and no stated parent or affiliated company. This supports classification as a standalone small manufacturing supplier.

After-Sales capabilityThe supplier reports clear procedures and followed records for corrective and preventive actions and customer complaints, plus written procedures and records for service-capability assessment. It also has in-stock capacity and has participated in an offline trade show, but lacks overseas warehouses, showrooms, agents, and branches, with zero countries stated for overseas services.

R&D capabilityThe supplier reports new products within the past year, offers ODM services, and uses AutoCAD, Pro/E, and SolidWorks; its R&D role includes new-product development, drawing design, and production technology support. However, no SDK is available and no auditable R&D design input, output, review, verification, or validation documents are available.

Production capacityThe supplier is a manufacturing factory with lathing, CNC, and automatic-lathing facilities, one quality inspector, standardized finished-product inspection instructions, stocked-service capacity, and stated lead times within 15 working days in both peak and off seasons. A material weakness is the absence of a valid contract between the factory and related subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also reports ODM capability. These repeated service descriptions provide direct evidence of broad customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and has participated in the OCT offline trade show. No specific customer names, project details, order history, or independently verifiable case information is provided.

Product Q&A

Q:How do I choose the right PDC bit for my formation?

It depends on the formation type. For soft to medium formations, use bits with larger cutters and an aggressive blade design for faster drilling. For hard and abrasive formations, choose bits with smaller cutters and higher impact resistance. Sending us your offset well data is the best way to get a precise recommendation.

Q:What causes a PDC bit to wear out quickly?

The main causes are excessive vibration (bit whirl or stick-slip), poor hole cleaning, or running outside the recommended WOB and RPM ranges. Keeping parameters within the advised window, maintaining good hydraulics, and monitoring downhole dynamics will significantly extend bit life.

Q:How long will a PDC bit last?

There's no set distance. it can range from a few hundred to several thousand meters, depending on the formation and operating conditions. A good rule of thumb: pull the bit when ROP drops significantly and can't be recovered by adjusting parameters. Pushing a dull bit too far risks leaving junk in the hole.
