AI-Powered supplier vetting

SummaryZhongshan Lifeng Hardware Manufacturing Co., Ltd. is identified as a professional fastener manufacturer and technical supplier with in-house R&D, production, testing, and customization capabilities. It offers sample-based, design-based, full, minor, and flexible customization, supported by solution design, prototyping, and mass production services. Manufacturing equipment includes cold heading, thread rolling, drilling, turning, grinding, and screw selection machines. Quality assurance is stated, but finished-product inspection is described as random or performed by packing staff, with one QA/QC inspector. The supplier reports no 3D software design, SDK, written service procedures, complaint-handling procedures, corrective-action records, approved supplier list, environmental impact assessment, or regular fire drills. Export-related capability is indicated by a stated 90% export-sales share, although the export-start field is recorded as 0 year. No certifications or customer cases are provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier and as a modern enterprise specializing in fastener R&D, production, sales, and service. Its company type is recorded as “Combined,” supporting classification as a manufacturing and service-oriented supplier.

After-Sales capabilityThe supplier describes end-to-end services including solution design, prototyping, and mass production, and accepts defined service terms and payment terms. However, it has no written service procedures or records for complaint handling, corrective and preventive actions, or supplier-service assessment, which indicates a documented after-sales management deficiency.

R&D capabilityThe supplier is identified as having professional technical R&D capability and states that technological innovation, process optimization, product precision, and durability are priorities. It also provides solution design and prototyping, although it does not provide 3D software design services.

Production capacityThe supplier reports mass-production capability and operates equipment including cold heading, thread rolling, drilling, lathes, grinders, and screw selection machines. It also states peak- and off-season lead times within 15 working days, but the annual productivity entry is incomplete, so capacity volume cannot be fully assessed.

Customization capabilityCustomization is explicitly available from samples and designs, including full, minor, and flexible customization. The supplier also describes customized fastening solutions and supports solution design, sample prototyping, and mass production.
