AI-Powered supplier vetting

SummaryLishui Wangong Precision Machinery Co., Ltd. is a limited company founded in 2008, with 98 employees and operations covering R&D, manufacturing, sales, and service. It manufactures precision transmission components, including linear shafts, ball screws, linear guides, cylinder rails, linear bearings, and roller linear rails. The supplier demonstrates documented service procedures, complaint handling, corrective and preventive actions, export licensing, OEM/ODM capability, and customization from samples and designs. Production infrastructure includes lathing, CNC machining, milling, and ultrasonic cleaning facilities, with documented finished-product inspection instructions. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas service coverage. Financial capacity is referenced for 2022–2024, but no financial performance details are provided.

Supplier typeThe supplier is identified as Lishui Wangong Precision Machinery Co., Ltd., a limited company founded in 2008. It is described as a combined business integrating R&D, production, sales, and service, and is not an offshore company or part of a larger company group.

After-Sales capabilityThe supplier has documented procedures and followed records for service capability assessment, corrective and preventive actions, and effective customer complaint handling. However, it has no overseas warehouse, showroom, agent, or branch, and reports service coverage in zero countries; therefore, its formal service processes are evidenced, while overseas after-sales reach is limited.

R&D capabilityThe supplier states that it has R&D capability, introduced new products during the past year, and provides ODM services. It can customize from samples and designs, but it explicitly has no available SDK; the available evidence supports product development capability but not a broader technology-platform capability.

Production capacityThe supplier manufactures multiple precision transmission components and operates lathing, CNC machining, milling, and ultrasonic cleaning facilities. It also has uniformly followed finished-product inspection instructions, but no quantitative productivity figures are provided and the audit evaluation result is recorded as 0, so overall production strength cannot be fully confirmed.

Customization capabilityThe supplier explicitly offers customization from samples and from customer designs, and also provides ODM services. These statements directly demonstrate both design-based customization and original design manufacturing capability.
