SummaryThe supplier is explicitly identified as a professional technical supplier offering 3D software design and multiple customization modes. Its stated business scope covers power equipment and electronic components, machinery and metal-related products. Production information includes seven production lines and lead times within 15 working days in both peak and off-season periods.
