AI-Powered supplier vetting

SummaryWenzhou Heyi Electrical Co., Ltd. is identified as a China-based limited company with trading and manufacturing descriptions, operating in Zhejiang and associated with electrical manufacturing. The supplier reports facilities for R&D, production, sales, marketing, and customer support, and offers customized solutions involving relays, shunts, proximity switches, current transformers, and sensors. It holds ISO 9001 certification, states that some products have CE and IEC approval, and reports 4 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. Reported products include relays, shunts, current transformers, and current sensors, with stated production quantities for several items and export markets across multiple regions. However, many requested capabilities—including OEM/ODM, SDK support, overseas services, traceability, innovation activity, and customer cases—are marked unknown. Audit information is present, but the evaluation result is recorded as 0 and its interpretation is not provided.

CertificationsThe supplier reports ISO 9001 certification and states that some products have received CE and IEC approval. A TUV Rheinland audit is also recorded with a validity period from 2025-03-27 to 2026-03-26, but the audit evaluation result is listed as 0 without an explained scale or conclusion.

After-Sales capabilityThe company description explicitly states that it has customer support facilities and provides close, personal service. However, overseas agents or branches, overseas warehouses, showrooms, and related service capacities are all marked unknown, so the breadth of after-sales coverage cannot be established.

R&D capabilityThe supplier states that it operates its own R&D facilities and has 6–10 R&D engineers, with experience in designing customized solutions. Specific evidence for new-product launches, SDK availability, private mold design, 3D design services, or documented product-development output is marked unknown.

Production capacityThe supplier reports dedicated production facilities, 4 production lines, and stated annual quantities for relays, shunts, current transformers, and current sensors. It also reports a lead time within 15 working days during off-peak seasons and exports to multiple global regions, although some annual productivity fields are incomplete.

Customization capabilityThe company explicitly describes itself as specializing in the design, manufacture, and delivery of customized solutions and states that it focuses on customer needs. Nevertheless, the specific availability of ODM, OEM, private-mold, and 3D design services is marked unknown.
