What is your warranty time and after-sales policy?

For equipment, we have a 1-year warranty and 2 years for the gearbox, excluding quick-worn spare parts. If problems occur within the warranty period, our engineers will analyze pics or videos to find a solution and replace components for free. If out of warranty, we advise sending to local dealers or self-repair with video support.

Are there any discounts for bulk orders?

Discounts are based on your order quantity. We also hold irregular promotions such as company anniversaries, mid-year promotions, and Christmas/New Year holiday promotions.

AI-Powered supplier vetting

SummaryThe supplier operates across equipment, security, firefighting, robotics, artificial intelligence hardware, machinery, components, and related technical or design services. It demonstrates broad customization capability, ODM services, recent new-product activity, and OEM service for known brands. Manufacturing information indicates two production lines, fewer than five quality-control staff, one R&D engineer, and one-month order fulfillment in both peak and off-peak periods. However, supplier-service controls are weak: no documented procedures or records were reported for supplier assessment, corrective actions, or complaint handling, and production batches are not continuously reconciled. The available information does not establish certifications, customer cases, or financial credibility; monetary figures are omitted.

Supplier typeThe supplier presents a broad equipment and industrial-product business scope, covering security and firefighting equipment, robots, AI hardware, pumps, mining and agricultural machinery, electrical equipment, components, repair, leasing, sales, design, and technical services. This supports classification as a diversified equipment and machinery supplier rather than a narrowly specialized provider.

After-Sales capabilityThe supplier reports no written procedures or records for effectively handling customer complaints, and no written corrective and preventive-action procedures or records. These are explicit weaknesses in documented after-sales and issue-resolution controls.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, indicating active product-development capability. However, it has only one year of total R&D-engineer experience and no available SDK, so the evidence supports product innovation but not a strong software-development platform capability.

Production capacityThe supplier operates two production lines and reports one-month fulfillment during both peak and off-peak periods. Nevertheless, it has fewer than five quality-control staff and does not continuously reconcile quantities for each batch or mass production, indicating capacity with material production-control limitations.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also states that ODM services are available, providing strong direct evidence of broad customization capability.
