AI-Powered supplier vetting

SummaryWenzhou Junke Electric Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory. Established in 1992, it states that it conducts R&D, manufacturing, distribution, sales, and customer support for low- and high-voltage switchgear and related electrical products. The supplier reports ISO 9001 and ISO 14001 certifications, 6–10 R&D engineers, 11–20 quality-control staff, and 10 production lines. Its listed annual product capacities range from 100,000 to 150,000 pieces across several product categories, and it exports to multiple regions, with exports representing 41%–50% of total sales. It claims to provide customized solutions and close customer service, but the available evidence does not independently verify service performance, customization outcomes, financial strength, or a broad customer portfolio. Recent trade records show transactions with buyers in the Philippines and Sri Lanka.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, with its own R&D, production, sales, and customer-support facilities. Its product portfolio covers electrical equipment such as automatic transfer switches, circuit breakers, meters, capacitors, and distribution panels.

CertificationsThe supplier reports ISO 9001 and ISO 14001 management-system certifications and states that some products have been approved by CE and IEC certificates. The evidence supports certification holding, although it does not provide certificate numbers, validity dates, or coverage details.

R&D capabilityThe company states that it specializes in research and design and maintains its own R&D facilities, with 6–10 years of total R&D-engineer experience reported. This supports an established product-development function, but no patents, new-product records, testing programs, or R&D achievements are provided.

Production capacityThe supplier reports its own manufacturing facilities, 10 production lines, and stated capacities of 100,000 pieces for automatic transfer switches and power capacitors, 150,000 pieces for meter sockets/meters, and 110,000 pieces each for soft starters/inverters and circuit breakers. It also reports 11–20 quality-control staff, indicating substantial stated production and quality resources.

Customization capabilityThe company explicitly describes its service as designing, manufacturing, and delivering customized solutions, and says it can help clients research electrical sources for panels. The evidence confirms a stated customization offering, though it does not provide specific customized projects, engineering scope, or delivery examples.

Client casesThe supplier identifies export markets across South America, the Middle East, Southeast Asia, Eastern Asia, Oceania, and Africa, and reports export activity beginning in 2010. Trade records show transactions involving ENEX ELECTRIC PHILS INC in the Philippines and MICRO POWER ENGINEERING PVT LTD in Sri Lanka, but the records shown are limited to individual transactions and do not establish a broad or independently verified customer track record.
