After-Sales capabilityFinished products are checked by packing staff, but the supplier has no written procedures or records for effective service-capability assessment, corrective and preventive actions, or customer-complaint handling. It also has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows, indicating limited documented and overseas service infrastructure.
R&D capabilityThe company describes 20 years of continuous innovation and modern precision technology, and its products are used in technically demanding sectors including CNC machine tools, wind power, robotics, and heavy industry. However, it explicitly reports no available SDK, so software-development integration capability is not demonstrated.
Production capacityThe supplier reports one manufacturing production line and one year of export experience, supported by two export-trade staff and one experienced export employee. It does not perform continuous quantity reconciliation for every batch or mass-production run, which is a stated production-control weakness.
Customization capabilityThe supplier explicitly reports customization from samples, designs, full customization, minor customization, and flexible customization. It also states that it provides OEM services for well-known brands, supporting a positive assessment of customization capability.
