It reports approximately 410 employees, a 10,000-square-meter facility, and ISO 9001:2015 certification. The supplier supports broad customization, including sample-based, design-based, full, minor, and flexible customization, and provides 3D software design services. Production-related evidence includes contracts with associated subcontractors and stated one-month lead times in both peak and off-season periods. Quality assurance and raw-material traceability are reported, but corrective-action records, complaint-handling procedures, supplier assessment procedures, and an approved-supplier list are not documented. The supplier has no stated in-stock capacity, overseas warehouse, or overseas showroom. Financial information is limited to year references without performance values, while...

Supplier typeThe supplier is identified as a limited company established in 2015, offering sheet metal fabrication, CNC machining, and wire harness products. Its stated business description also includes precision CNC parts and injection molding manufacturing, indicating a technical manufacturing supplier rather than a trading-only entity.

CertificationsThe company description explicitly states that the supplier holds ISO 9001:2015 certification. No other certifications are identified in the provided information.

After-Sales capabilityThe supplier reports a corrective and preventive action procedure, but no written records; it also has no written procedures or records for handling customer complaints. Service-capability assessment procedures and an approved supplier list are likewise absent, so effective after-sales governance is not demonstrated.

R&D capabilityThe supplier identifies itself as a professional technical supplier and confirms R&D capability and 3D software design services. However, it reports no available SDK, so the evidence supports design and technical development capability but not SDK-based integration capability.

Production capacityThe supplier states ten years of experience in sheet metal fabrication, precision CNC parts, injection molding, and wiring harness manufacturing, with a 10,000-square-meter facility and approximately 410 employees. It has valid manufacturing contracts with associated subcontractors and reports one-month lead times in both peak and off-season, but lacks in-stock, overseas warehouse, and overseas showroom capacity.

Customization capabilityThe supplier supports customization from samples and designs, full customization, minor customization, and flexible customization. It also provides 3D software design services, demonstrating broad product-design and customization support.
