AI-Powered supplier vetting

SummaryThe supplier demonstrates flexible customization, ODM and OEM capability, recent new-product activity, ISO 9001 certification, in-stock capacity, and more than 15 years of heat-treatment experience. It has export capability, eight years of exporting experience, and access to overseas agents or branches, but no overseas warehouse or showroom and no participation in offline trade shows. Operational controls show weaknesses: there is no valid manufacturing-capacity contract with its related subcontractor, no written supplier-service assessment or approved-supplier list, no written corrective-action or complaint-handling procedures, and no raw-material traceability. Quality inspection is performed by one inspector, with finished products checked by packing staff. Innovation evidence is limited by zero stated patents, no SDK, no private molds, and no 3D software design service. Financial records are identified for 2021–2023, but their results are not provided.

Supplier typeThe supplier is a manufacturing-oriented provider with CNC lathe and CNC processing facilities, in-stock capability, self-operated import/export rights, and stated experience in heat treatment. It also offers services through overseas agents or branches, but the stated number of countries with overseas services is zero and no overseas warehouse or showroom is available.

CertificationsThe supplier reports an ISO 9001 supplier management-system certification. This is explicit evidence of a recognized quality-management certification, although no other certifications are identified.

After-Sales capabilityThe supplier accepts several service payment methods and states peak-season lead time of one month and off-season lead time within 15 workdays. However, it has no written corrective and preventive action procedures or records and no written customer-complaint handling procedures or records, limiting evidence of structured after-sales management.

R&D capabilityThe supplier reports a new product within the past year, flexible design customization, ODM service, and use of AutoCAD and SolidWorks. Innovation infrastructure appears limited by no available SDK, zero stated R&D patents, no private-mold capability, and no 3D software design service.

Customization capabilityThe supplier explicitly provides flexible customization, can analyze and design products according to customer usage, and can process supplied drawings. It also reports ODM and OEM capability, providing strong direct evidence of customization support.

Product Q&A

Q:Which reverse circulation hammer matches QIDELI RE004 & RE542 drill bits?

They are fully compatible with QIDELI NRC series reverse circulation DTH hammers, perfectly matched for deep geological core sampling drilling.

Q:What diameter sizes do RE004 and RE542 bits support?

RE004 head diameters: 115/121/124/127mm; RE542 head diameters: 121/124/127/133mm, all with 8 splines and 2 exhaust holes.

Q:Will the drill bit pollute my rock core samples during drilling?

No. Adopting patented drop-center face structure, the bits separate debris and core samples effectively to guarantee uncontaminated intact samples.

Q:What treatment is applied to the carbide buttons for wear resistance?

All dome tungsten carbide buttons go through professional carburizing treatment, offering strong abrasion resistance for hard rock and loose soil drilling.

Q:Do I need to disassemble the hammer to change different size drill bits?

No. Integrated sample tube matching design supports direct bit replacement without hammer disassembly, saving construction time greatly.
