SummaryNingbo Tianhui Machine Co., Ltd. is a Chinese manufacturer/factory producing CNC-machined, cast, and forged metal products, with a stated scope also covering hardware machinery, plastics, and electronics. It reports broad customization and ODM capabilities, new product development in the past year, relevant machining and inspection equipment, and experience supplying customers in Japan, Italy, Germany, and automotive-related applications. Export sales are stated at 71%–90%, with 16 years of exporting and self-operated import/export rights. Quality procedures include documented inspection instructions, corrective and preventive action procedures, complaint-handling procedures, and quality assurance. However, the supplier has no overseas agents or branches, warehouse, showroom, or offline trade-show participation, no available SDK, and no valid manufacturing-capacity contract with associated subcontractors. Certification ownership and after-sales service coverage are not sufficiently evidenced.
