CertificationsThe supplier reports holding an ISO 9001:2015 certificate. No other certification details, scope, issuing body, or validity information are provided.

After-Sales capabilityThe supplier has written procedures and followed records for service-capability assessment, corrective and preventive actions, and customer complaint handling.

These stated capacities provide explicit evidence of substantial production capability.

Customization capabilityThe supplier states that it can customize from samples and designs, provide full, minor, and flexible customization, and offer ODM and OEM services. It does not provide 3D software design services, so customization is supported but not through that specific design tool capability.
