AI-Powered supplier vetting
SummaryThe supplier manufactures and supplies optical coating filters and operates three production lines, with stated annual output of 5,000 L-Pro sets and seven quality assurance or quality control inspectors. It provides customization from samples, designs, and minor customization, as well as ODM and OEM services. Its service system includes written procedures and records for supplier assessment, corrective and preventive actions, and customer complaints. The supplier exports to multiple regions and reports peak-season lead time of one month and off-season lead time within 15 workdays. However, it does not provide 3D software design services, has had no new products in the past year, has one R&D engineer, lacks available SDKs, and has no R&D audit documentation available. No certification information or specific customer cases are provided. Overseas service infrastructure is limited: there is no overseas warehouse or showroom, although overseas agents or branches and offline trade-show participation are reported.
Supplier typeThe supplier is a manufacturer and seller associated with optical and equipment-related activities, with optical coating filters identified as its offered product. It operates three production lines and reports production of L-Pro products, indicating a manufacturing-oriented supplier rather than only a trading intermediary.
After-Sales capabilityThe supplier has written procedures and followed records for handling customer complaints, as well as corrective and preventive actions. It also reports overseas agents or branches and participation in Analytica China, but has no overseas warehouse or showroom and lists zero countries where overseas services are offered; the evidence supports formal complaint handling but not broad overseas service coverage.
R&D capabilityThe supplier offers ODM and has one R&D engineer whose stated responsibility is reviewing customer order requirements, but it does not provide 3D software design services, reported no new products in the past year, has no available SDK, and lacks R&D design input, output, review, verification, and validation documents for audit. These explicit limitations indicate weak demonstrated innovation capability.
Production capacityThe supplier operates three production lines, reports annual output of 5,000 L-Pro sets, and has seven quality assurance or quality control inspectors. It also lists production and processing equipment and states off-season lead time within 15 workdays and peak-season lead time of one month, providing explicit evidence of established production capacity.
Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, and minor customization. It also reports ODM and OEM capability, although the absence of 3D software design services limits the scope of design-support capability.
