AI-Powered supplier vetting

SummaryWeshine Electric Manufacturing Co., Ltd. is identified as a limited-company factory producing testing equipment, with 53 employees and no stated parent group affiliation. It provides multiple customization options and ODM services, and reports OEM service for well-known brands. Service processes, corrective and preventive action procedures, and complaint-handling procedures are documented and supported by records. However, the supplier reports no new products in the past year, no available SDK, no valid manufacturing contracts with affiliated subcontractors, and no overseas warehouse, showroom, agents, or branches. An audit by TUVRHEINLAND is listed, but the provided audit result is coded as “0” without an explanatory interpretation. Financial information is present only as reporting years and contains no assessable financial performance data.

Supplier typeThe supplier is identified as Weshine Electric Manufacturing Co., Ltd., a limited company and factory focused on testing equipment. It is described as a combined company, not an offshore company, and is not part of a larger company group.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. It reports in-stock capability and one-month lead times in both peak and off-season, but lacks overseas warehouses, showrooms, agents, and branches, with no overseas service countries stated.

R&D capabilityThe supplier offers ODM services and reports several design-service options, but it had no new products during the past year and has no available SDK. The evidence therefore shows some development-service capability but limited recent innovation evidence.

Production capacityThe supplier is identified as a factory producing testing equipment, has in-stock capability, reports one-month average lead times in both seasons, and lists six qualified suppliers. However, it reports no valid contract between the factory and related subcontractors, creating a documented manufacturing-governance deficiency.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, and full customization, as well as ODM services. This directly demonstrates broad customization coverage.

Product Q&A

Q:What types of relays can this device test?

It tests traditional relays, protection devices, and modern microcomputer protections, especially transformer differential and standby automatic switching devices.

Q:Does the device support DC voltage output?

Yes, it has an independent DC auxiliary voltage source outputting 110V (1A) and 220V (0.6A) for relays needing DC power.

Q:How is the system protected against crashes?

The Windows XP system includes a recovery function to avoid crashes caused by illegal shutdowns or misoperations.

Q:What is the frequency range and accuracy?

The frequency range is 0-1000Hz with an accuracy of 0.01Hz (or 0.001Hz depending on specific parameter section), and phase accuracy is 0.1 degree.

Q:Can the device be used with a laptop?

Yes, it can connect to a laptop (optional) using the same software as the industrial computer, allowing for portable operation.
