AI-Powered supplier vetting

SummaryThe supplier is a combined company engaged in developing, designing, manufacturing, and selling industrial equipment functional components and related machinery. Its stated products include ball screws, linear guideways, roller guides, ball splines, and ball bushings, supported by a 157,560 m² manufacturing plant. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and has conducted fire drills and completed a factory environmental impact assessment. The supplier offers extensive customization and ODM services, but reports no professional technical R&D capability, no new products in the past year, and no SDK or 3D software design service. Production-related controls and supplier-service procedures exist but lack written records in several areas. It has in-stock capability and long export experience, while lacking an effective manufacturing contract with an affiliated subcontractor, overseas warehouse, and overseas showroom. Customer cases and verified financial performance cannot be...

Supplier typeThe supplier is identified as a combined company whose scope covers development, design, manufacture, and sales of industrial equipment functional components, precision machinery, rubber and plastic machinery, electrical machinery, and accessories. This establishes a manufacturing-oriented industrial supplier rather than a purely trading or offshore entity.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. It also has a factory environmental impact assessment report and conducted regular fire drills during the past year, providing explicit evidence of quality, occupational safety, and environmental management certifications and activities.

R&D capabilityThe supplier reports no professional technical R&D capability, no new products during the past year, no SDK availability, and no 3D software design service. Although it offers ODM services, these stated limitations do not demonstrate strong innovation capability.

Production capacityProduction capacity is supported by a 157,560 m² manufacturing plant, in-stock capability, 60 qualified service-capability suppliers, and stated quality assurance. However, the supplier reports no valid contract between the factory and an affiliated subcontractor, and several control procedures lack written records, so production scale is evident but governance and documentation have weaknesses.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization, and also offers ODM services. This is direct evidence of broad customization coverage despite the absence of 3D software design services.
