It reports TS 16949 and ISO 9001 certifications, more than 10 production lines, 6–10 quality-control staff, and shipment inspection reports with material certificates. The supplier provides 3D software design, ODM, and several customization options, but reports no new products in the past year, no SDK, and no OEM service for popular brands. Service infrastructure is limited: no in-stock capability, overseas warehouse, or overseas showroom, while service assessment, complaint handling, and corrective-action procedures lack written records. Financial information is limited to year labels without substantive performance values. No customer cases are provided.

Production capacityThe supplier operates more than 10 production lines, has 6–10 quality-control staff, and offers a broad metal, machining, casting, plastic, rubber, and vehicle-parts scope.
