After-Sales capabilityThe supplier reports written procedures and followed records for service-capability assessment, corrective and preventive actions, and customer complaint handling. However, it reports no overseas showroom, overseas agent or branch, or offline trade-show participation; overseas service details are limited to training, so broad international after-sales coverage is not established.

R&D capabilityThe supplier reports R&D and design capabilities and provides 3D software design services, but also states that it had no new products during the past year. This supports the existence of technical development capability but does not demonstrate recent product innovation.

Production capacityThe supplier describes itself as integrating R&D, design, production, and service, with automated production equipment, technical capability, process control, and quality inspection. Its stated scope includes manufacturing-related products and equipment, but no quantitative production capacity, output, or independently verified manufacturing evidence is provided.
