AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with in-house machinery, design, production, installation, and technical-service capabilities. It offers flexible, minor, full, design-based, and sample-based customization, plus 3D software design services. However, quality and service controls are weakly documented: only one quality inspector is reported, finished products are checked by packing staff, and there are no written procedures for service assessment, corrective actions, complaint handling, or quality assurance. Production capacity is indicated by one production line, while ongoing quantity reconciliation is not performed. The supplier has no export experience and offers no overseas services, although two export-experienced staff are reported. Financial records are referenced for 2022–2024, but their performance cannot be assessed from the provided information. No certifications or customer cases are explicitly documented.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated scope includes machinery and environmental-protection equipment sales and manufacturing, equipment installation, and technical services, while its company description indicates an in-house machinery factory integrating design, production, and supply.

After-Sales capabilityTechnical service and equipment installation services are within the stated business scope, and service quotations and payment terms are listed. However, the supplier has no written or recorded procedures for service assessment, corrective and preventive actions, or effective customer complaint handling, limiting evidence of structured after-sales capability.

R&D capabilityThe supplier provides 3D software design services and supports multiple customization modes, and it claims in-house design and fabrication resources. However, no SDK is available, so the evidence supports design capability but not SDK-based development or integration.

Customization capabilityThe supplier explicitly offers flexible, minor, full, design-based, and sample-based customization, supported by 3D software design services and an in-house design and fabrication team. These slices provide direct evidence of broad customization options.

Product Q&A

Q:Are you a factory?

Yes, we are a factory with a 3200 square meter workshop and office.

Q:What is the gold recovery rate of your equipment?

The recovery rate depends on particle size, shape, feed presentation, and sluicebox design. While some claim 80-90%, actual rates vary, but 90% of placer mining plants use sluice boxes for optimal results.

Q:What is the difference between a gold trommel and a gold shaker deck?

Trommel screens offer longer maintenance intervals and lower operating costs, while shaker decks handle higher tonnage throughput and allow for primary sluice runs. Both can be configured for most ground conditions.

Q:What is the delivery time?

Most models are in stock and ship within 10-15 days after receiving the deposit. If not in stock, production takes 3-4 weeks.

Q:Do you supply accessories for gold wash plants?

Yes, we supply all accessories and tools, including water pumps, layflat hoses, diesel generators, and can even source trucks, wheel loaders, bulldozers, and excavators.
