AI-Powered supplier vetting

SummaryZhejiang Lingshine Electric Co., Ltd. is a high-tech manufacturer and integrated production, sales, and service enterprise focused on power semiconductor and industrial control products. It reports CE and CCC certifications, OEM and ODM services, broad customization options, documented finished-product inspection instructions, and stated annual capacities across several product categories. Its R&D team has four engineers and uses AutoCAD, but there are no available R&D audit documents, no new products reported in the past year, no 3D design or SDK support, and limited evidence of formal service-management controls. The supplier has no overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. No Fortune 500 customer cooperation or repeat-buyer preference is reported, so customer-case strength is not demonstrated.

Supplier typeThe supplier describes itself as a high-tech enterprise integrating production, sales, and service, with products including power SCRs, frequency converters, soft starters, solid-state relays, voltage regulators, and high-power rectifiers. This supports classification as a manufacturer and integrated industrial-electronics supplier.

CertificationsThe supplier reports CE and CCC product compliance certifications, and the same certifications are identified for sustainable development and product certification capability. This is explicit evidence of holding relevant certifications, although the provided information does not specify product scope or validity details.

After-Sales capabilityR&D responsibilities include technical support for after-sales service, but service-capability procedures are incomplete: written assessment procedures have no records, corrective and preventive action procedures are absent, and complaint-handling procedures or records are absent. The supplier also lacks overseas service infrastructure, including warehouses, showrooms, agents, and branches.

Production capacityThe supplier reports annual capacities of 12,000 soft starters, 100,000 solid-state relays, 100,000 rectifier bridges, and 10,000 power SCR regulators. It also states that finished-product inspection instructions exist and are uniformly followed, supporting established production and inspection capability.

Customization capabilityThe supplier explicitly offers full customization, customization from designs and samples, minor customization, flexible customization, and ODM services. These statements directly support broad customization capability, although the absence of 3D software design services may limit certain design workflows.
