    Top Questions from OKmarts Buyers

    • Q: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?

      A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.

    • Q: Can we request customized modifications for heavy wear components or specialized industrial parts?

      A: Through our network of partner factories and flexible manufacturing technologies, we support customized production runs for specific structural or wear components. Technical drawings (CAD/STEP files) must be submitted for engineering review and custom prototyping quotes.

    • Q: What express logistics options are available for urgent "Factory-Down" emergency repairs?

      A: We partner with premier global express couriers, including DHL, FedEx, and UPS, to provide expedited international air freight. Urgent orders are processed with priority handling at our warehouses to ensure the shortest possible transit time to your facility.
