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:What makes QIDELI drill bits stand out in extreme hard rock drilling?

We adopt self-developed QK05 alloy. Compared with the internationally recognized YK05 alloy in China, QK05 alloy shows higher performance in working scenarios with extremely hard rocks, ensuring more stable and efficient drilling.

Q:How does QIDELI ensure the reliability of drill bits during long-term wear?

Relying on our mature alloy inlay technology, the bonding between the alloy and the drill bit body is extremely strong. Even under the severe wear conditions shown in the figure, our drill bits hardly have tooth loss problems, which is a key advantage over ordinary products.

Q:Why are QIDELI drill bits highly praised for their cylinder body stability in the Kazakhstan market?

We have focused on heat treatment technology research since 2005, and now have very mature technology. For our 45A-115mm and 45A-130mm drill bits, only 2-3 out of every 1,000 units have cylinder body damage. This stability is far higher than the industry average, winning trust from local customers.

Q:How is your quality control?

We have a professional and experienced in-house QC team. Every order will undergo strict inspection and testing before shipment to ensure product quality meets the standards.

Q:Is it difficult to operate and make the graph?

The instrument is easy to operate, and we will send you a detailed operation manual via email. The detector supports one-button direct mapping, without the need for computer-aided drawing.
