It holds CE and ISO9001:2015 certifications, maintains written procedures for finished-product inspection, supplier-service assessment, corrective actions, and complaint handling, and reports inventory capability. However, it does not provide 3D software design, has no overseas warehouse, showroom, agents, or branches, and offers services in zero stated countries. No valid manufacturing-capacity contract with related subcontractors is reported.

After-Sales capabilityWritten procedures and followed records are reported for supplier-service assessment, corrective and preventive actions, and customer complaints.
