AI-Powered supplier vetting

SummaryThe supplier manufactures and sells rubber products, tires, testing machines, mechanical equipment, and electronic specialized equipment, and provides related technical services. It reports four production lines, 6–10 quality-control staff, and air-spring output of 1,800,000 sets. Customization is available from samples and designs, including full, minor, and flexible customization. Service-management, corrective-action, complaint-handling, and finished-product inspection procedures are documented and followed. However, no supplier-management-system certification, overseas warehouse, showroom, agent or branch, or offline trade-show participation is reported. The supplier provides OEM services for known brands but has no available SDK. Financial information is insufficient for a reliable assessment, and no specific customer cases are supplied.

Supplier typeThe supplier operates as a manufacturer and seller of rubber products, tires, testing machines, mechanical equipment, and electronic specialized equipment, while also providing technical services. The establishment of a Chinese production base with TIP-TOPOL and Dombetter Automotive Technology further supports its classification as a manufacturing-oriented supplier.

After-Sales capabilityThe supplier has documented and followed procedures for service-capability assessment, corrective and preventive actions, and effective customer-complaint handling. However, it reports no overseas warehouse, showroom, agent or branch, and no overseas service countries, indicating limited overseas service infrastructure despite formal service procedures.

Production capacityThe supplier reports four production lines, 6–10 quality-control staff, and annual air-spring output of 1,800,000 sets. Its Chinese production base was expected to start production at the end of 2025, while key rubber membranes still come from the European base; these details demonstrate stated production resources but also indicate some dependence on the European supply base.

Customization capabilityThe supplier explicitly supports customization from samples and designs, including full customization, minor customization, and flexible customization. It also reports a finished-product inspection method with written instructions that are uniformly followed, supporting execution of customized orders.
