SummaryThe supplier is identified as a professional technical supplier with 3D software design, ODM, OEM, and full customization capabilities. It holds an ISO 9001:2015 certificate and reports quality assurance, 50 quality-control staff, two production lines, and documented finished-product inspection instructions. However, its R&D profile is limited by only two years of total R&D engineer experience, no new products reported in the past year, and no available SDK.

Manufacturing capacity is not supported by a valid contract with related subcontractors, while stated production lead times are 2–3 months in both off-peak and peak seasons. The company reports stable relationships with domestic and overseas customers, but no specific customer names or verifiable customer cases are provided.
