AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing and export capabilities, including five production lines, OEM service for well-known brands, ISO 9001 certification, documented quality and service procedures, and 100% finished-product inspection. It supports customization from samples, designs, and full specifications, and provides raw-material traceability. Export sales account for 90% of total sales, with markets across multiple regions and experienced export personnel. Lead times are stated as within 15 working days in both peak and off-peak seasons. However, the supplier reports no available SDK, no overseas warehouse, showroom, agent or branch, and no offline trade-show participation. Manufacturing lacks continuous quantity reconciliation for every batch. Financial information identifies reporting years but provides no assessable financial metrics. Customer-specific cases are not explicitly documented.

Supplier typeThe supplier is a manufacturing-oriented OEM exporter: it operates five production lines, provides OEM services for well-known brands, exports 90% of sales, and serves markets across South America, the Middle East, North America, Southeast Asia, Eastern Asia, Oceania, and Africa. Its stated export and service coverage is supported through trade terms and port access, although it reports zero countries with overseas services.

CertificationsThe supplier holds ISO 9001 certification, providing explicit evidence of a recognized quality-management-system certification.

After-Sales capabilityThe supplier has written procedures and records for service capability assessment, corrective and preventive actions, and customer complaint handling. However, it has no overseas warehouse, showroom, agent, or branch, and reports no countries with overseas services, limiting evidence of localized after-sales coverage.

R&D capabilityThe supplier has 6–10 years of total R&D-engineer experience and offers multiple customization modes, including design-based and full customization. However, it explicitly reports no available SDK, so software-development or SDK support is not demonstrated.

Production capacityThe supplier operates five production lines, employs 21–30 quality-control staff according to one record, conducts 100% finished-product inspection, provides raw-material traceability, and states lead times within 15 working days in both peak and off-peak periods. A limitation is that it does not continuously reconcile quantities for every batch or bulk production, and another record lists only one quality-assurance and quality-control inspector.

Customization capabilityThe supplier explicitly supports OEM services for well-known brands and offers customization from samples, designs, full specifications, minor changes, and flexible requirements. These statements provide direct evidence of broad product customization capability.

Product Q&A

Q:What is the main positioning and core highlights of the Doosan DX300 excavator?

The Doosan DX300 is positioned as a 'highly efficient and versatile' 30-ton general-purpose excavator, particularly renowned for its exceptional fuel economy. Its core highlight is the intelligent dual fuel saving system. Through the synergy of the EPOS Intelligent Control System and SPC Intelligent Fuel Saving Technology, it can freely switch between 6 modes based on working conditions, achieving the optimal balance between power and fuel consumption, hence its titles as the 'Fuel Saving Star'

Q:Beyond fuel saving, how are the operating speed and efficiency of the DX300?

While offering excellent fuel economy, the DX300 also delivers outstanding operating efficiency. Its boom and arm feature fast lifting and lowering speeds, with smooth, precise, and coordinated compound movements. Its strong swing torque ensures powerful and quick rotation, and its compatibility with attachments like breakers allows it to easily handle heavy-duty, high-cycle tasks such as small-scale mining operations, comprehensively improving work efficiency.

Q:Is the DX300 highly adaptable? What different types of projects can it be used for?

The DX300 is an extremely versatile excavator. Its fast compound operation capability, smooth and precise movements, and backhoe design (forced soil cutting) allow it to perfectly adapt to various operating modes. It is capable of handling tasks ranging from earthmoving and pipeline laying in large municipal projects, to ore loading and demolition in small-scale mines, as well as general construction work, meeting diverse engineering needs.

Q:What is the approximate working hours of the used excavators? Can I choose?

Yes, they are available for selection. We can provide multiple options.

Q:How steep a slope can the muck loader handle? Do you have explosion-proof models?

We have tracked muck loaders suitable for steep slopes. Explosion-proof models are available. Choose according to your needs.
