AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturer located in Shenzhen, with two production lines, 6–10 quality-control staff, and an off-peak lead time within 15 working days. It reports broad customization services, recent new-product activity, ODM capability, and OEM service for well-known brands. However, quality and service-management controls appear weakly documented: finished products are checked by packing staff, and no written procedures or records are reported for supplier service assessment, corrective actions, or complaint handling. Financial-related records are indicated for 2021–2023, but no substantive financial performance details are provided. No certifications, SDK, overseas facilities, overseas agents, branches, or trade-show participation are evidenced. Customer cases are not specifically disclosed.

Supplier typeThe supplier is explicitly classified as a manufacturer, with a factory in Baotian Industrial Zone, Shenzhen. It operates two production lines and reports 6–10 quality-control staff, supporting a direct manufacturing profile.

After-Sales capabilityThe supplier reports no written procedures or records for effective customer-complaint handling, corrective and preventive actions, or service-capability assessment. It also has no overseas warehouse, showroom, agent, or branch, limiting evidenced overseas service infrastructure.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services and multiple design-based customization options. However, its R&D engineering experience is listed as 1, and no SDK is available, so innovation capability is evidenced but appears limited in depth.

Production capacityThe supplier is a manufacturer with two production lines, 6–10 quality-control staff, and an off-peak lead time within 15 working days. Nevertheless, finished products are checked by packing staff, and the stated export-market information is primarily domestic, so production scale and quality-control sophistication are only partially evidenced.

Customization capabilityBoth R&D and general design-service records explicitly list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing direct evidence of broad customization support.

Product Q&A

Q:What is the maximum detection depth?

The detector can reach depths of up to 15 meters. For larger objects (30x30 cm), depth ranges from 5 to 8 meters, and up to 12 meters for long-buried items.

Q:What types of metals and gems can be detected?

It specializes in detecting Gold, Silver, Copper, and Gemstones (such as diamonds). Note: Avoid selecting two metals simultaneously to prevent instrument damage.

Q:What is the search range of this detector?

The search system extends up to an impressive 1000 meters, managed by a microcomputer processor control and reflective conductivity.

Q:Is the product customizable?

Yes, the product is customized. Options include detection types, weight (3.2kg), emission frequency (5.6-6kHz), and power source (12V 1600mA).

Q:What is the warranty period and coverage?

We provide a 1-year warranty against non-human damage. Defective products are eligible for exchange. Tampering with the machine voids the warranty.
