This supports classifying it as an integrated manufacturer and trading/service supplier.

After-Sales capabilityThe supplier reports overseas warehouse and showroom capabilities and offers debugging, maintenance, repair, training, and equipment installation. It also has documented complaint-handling and corrective-action procedures, but reports no overseas agents or branches and zero countries offering overseas services, limiting evidence of broad local coverage.

It also reports total R&D engineer experience of 6–10 years, providing explicit evidence of development capability.

Production capacityThe supplier reports eight production lines, valid manufacturing-capacity contracts with associated subcontractors, inventory capability, and lead times within 15 working days in both peak and off-peak records. Quality controls include 100% finished-product inspection, although the factory does not continuously reconcile quantities for every batch or mass production.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This directly demonstrates broad customization coverage.
