AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design and flexible customization. Its stated business scope covers mechanical parts, gears, bearings, transmission components, vehicle parts, and various industrial and consumer-related products. Production resources include CNC lathes, CNC machining centers, cutting, drilling, punching, and automatic tapping equipment, with two quality inspectors. It reports inventory capability, export sales of 71%–90%, Shanghai Port proximity, and lead times within 15 working days in both peak and off-season. However, there is no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and no written procedures or records for service assessment, corrective actions, or complaint handling. ISO9001:2015 and RoHS are reported. No new products were developed in the past year, and the provided financial figures are zero or insufficient for credibility assessment.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its business scopes include mechanical parts processing and sales, gears and transmission parts, bearings, vehicle and machinery parts, and related trading activities, indicating a technical manufacturing and trading profile.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and RoHS product compliance certification. These stated certifications support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports in-stock service capability and accepts multiple quotation and payment terms, but has no written procedures or records for service-capability assessment, corrective and preventive actions, or customer-complaint handling. It also lacks an overseas warehouse and showroom, limiting evidence of structured international after-sales support.

Production capacityProduction-related evidence includes CNC lathes, CNC machining centers, cutting, drilling, punching, and automatic tapping equipment, two quality inspectors, inventory capability, and order lead times within 15 working days. However, the supplier has no valid manufacturing-capacity contract with related subcontractors, so production capacity is supported but not fully secured through documented contracting.

Customization capabilityThe supplier explicitly reports flexible customization in both its R&D design services and design-services capability, and it offers 3D software design services. These statements directly support an ability to provide customized technical solutions.

Product Q&A

Q:Have you supplied products for racing brands or events?

Yes, we have been providing OEM support to various racing suspension brands across Europe and the US, including motorsport tuners, rally car builders, and kart manufacturers.

Q:How can I estimate or calculate the service life of your bearings?

The service life of a bearing (in oscillation cycles) depends on factors such as load, oscillation angle, frequency, and temperature. Although precise prediction is complex, standard industry formulas can provide useful estimates.

Q:Do your bearings produce abnormal noise under high-speed compression and rebound?

No. Our PTFE self-lubricating liner eliminates metal-on-metal contact, preventing dry friction issues. This ensures smooth and silent operation during high-speed compression-rebound cycles.Internal tests show no abnormal noise over 1 million compression-rebound cycles.

Q:Can you support annual supply agreements or batch delivery plans for racing projects?

Yes, we support OEM production and racing project supply. Services include annual framework agreements, monthly deliveries, and customized batch labeling.
