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 is the maximum current output capability?
A:
The device provides 0-40A per phase, and up to 120A when 3 phases are connected in parallel.
Q:Does the tester support GPS synchronization?
A:
Yes, it supports optional built-in GPS synchronization cards for remote swap testing between two testers.
Q:What is the warranty period for this product?
A:
The product comes with a 1-year warranty and 7*24 online after-sales service.
Q:Can the device output DC voltage for relays?
A:
Yes, it has a separate DC auxiliary voltage source outputting 110V(1A) and 220V(0.6A).
Q:Is customization available for this tester?
A:
Yes, the product is customized and supports OEM/ODM services including full and minor customization.
