AI-Powered supplier vetting

SummaryInnovake demonstrates established manufacturing, customization, quality-management, and technical-service capabilities. It offers sample-, design-, and fully customized solutions, has five quality inspectors, maintains traceability for raw materials, and reports ISO9001, ISO14001, and ISO45001 certifications. The supplier provides inventory support, domestic after-sales resources, debugging, maintenance, and repair services, but has no overseas warehouse, showroom, or recorded overseas-service country coverage. Its innovation profile is supported by recent new products, an internal R&D center, high-tech enterprise recognition, and SDK availability, although it is not classified as a professional technical supplier and does not provide ODM services. Production lead time is stated as one month in both peak and off-season periods. Financial credibility cannot be assessed because the provided information contains only a year reference and no substantive financial evidence.

Supplier typeThe supplier is identified as not being a professional technical supplier, while its business scope covers parts processing, mechanical parts, machinery and equipment sales, equipment repair, installation, and related industrial services. This indicates a broad industrial machinery and parts supplier profile rather than a specialized professional technical supplier.

CertificationsThe company states that it has passed ISO9001 Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System certifications. These explicitly support compliance across quality, environmental, and occupational-safety management.

After-Sales capabilityThe supplier has service offices in Nanjing, Tangshan, and Anshan, with service engineers, vehicles, and parts warehouses; it also reports inventory capability, clear complaint-handling procedures with records, and debugging, maintenance, and repair services. However, it has no overseas warehouse or showroom and reports service coverage in zero countries, so the evidence supports domestic service strength but limited overseas infrastructure.

R&D capabilityThe supplier reports new products within the past year, an established Innovation and R&D Center, recognition as a national High-tech Enterprise and technology-based SME, and SDK availability. These are explicit indicators of innovation and technical development, although the supplier does not provide ODM services and is not classified as a professional technical supplier.

Production capacityProduction-related evidence includes parts processing and machinery capabilities, valid manufacturing contracts with associated subcontractors, inventory capacity, five quality inspectors, and a stated one-month average lead time in both peak and off-season periods. Supplier-service procedures are documented and followed, supporting an established production and fulfillment structure.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and full customization, and also provides 3D software design services. This directly demonstrates broad customization coverage for customer-specific requirements.

Client casesThe supplier participated in a steel equipment spare-parts procurement and quality exhibition organized by Hesteel Group Supply Chain Management Company and reports OEM service for well-known brands. These references provide evidence of industry-related engagement and OEM experience, although no specific customer names or detailed project outcomes are provided.

Product Q&A

Q:What is the core difference between DTH bits and ordinary drill bits?

DTH bits work with DTH hammers, breaking rock through a combination of high-frequency impact and rotation, making them suitable for deep-hole drilling in hard rock. Ordinary drill bits rely more on rotational cutting and are better for soft formations or shallow drilling.

Q:What are the main factors affecting the service life of DTH bits?

These include rock hardness and abrasiveness, hammer air pressure (excess pressure can cause tooth chipping), smoothness of slag discharge (blockages accelerate wear), and the quality of the bit material.

Q:What may cause frequent bit jamming during drilling?

Possible reasons: unreasonable design or blockage of slag discharge channels; loose connection between the bit and DTH hammer; excessive deviation of the drilling angle leading to hole wall collapse.

Q:How to choose the diameter of a DTH bit?

It should match the specifications of the DTH hammer (e.g., a 110mm hammer corresponds to a 115mm bit) and align with the required drilling diameter for the project (commonly 80-300mm).
