SummaryXiamen Camum Precision Tools Co., Ltd. is identified as both a trading company and manufacturer/factory in China, offering cutting tools and machining products for industries including molds, automotive, and aviation. The available information indicates three production lines, 11–20 quality-control staff, and R&D engineer experience of 6–10 years. It exports primarily to Southeast Asia, with recorded transactions involving one Mexican buyer for inserts and taps in 2025. The company states a commitment to stable quality, service, and continuous innovation, but no certifications are provided. Its stated lead times are 4–6 months off-season and 2–3 months peak season, and its export sales share is 11%–20%. Evidence is insufficient to establish financial strength, formal after-sales processes, or broad customer coverage.
Supplier typeThe supplier is explicitly classified as both a trading company and a manufacturer/factory. It is a limited company based in Fujian, China, with a stated factory location in Shanghai in another record, indicating manufacturing-related operations but also a location discrepancy requiring verification.
R&D capabilityThe company states that it continuously introduces advanced cutting and hole-machining tools and identifies continuous innovation as a business philosophy. R&D engineers are reported to have 6–10 years of total experience, supporting innovation capability, although no specific patents, new products, or development results are provided.
Production capacityThe supplier is identified as a manufacturer/factory offering inserts, cutters, end mills, drill bits, and custom tools, with three production lines and 11–20 quality-control staff. Its stated applications include mold, automotive, and aviation industries, although capacity, equipment details, and output volumes are not disclosed.
Customization capabilityThe product keywords explicitly include “Special Tool” and “Custom Tool,” indicating an offered customization capability. The slices do not provide details on customization scope, engineering process, minimum order requirements, or delivery performance for customized products.
Client casesTrade records show transactions in 2025 with HJ PRECISION CUTTING SA DE CV in Mexico for products described as inserts and taps, with one to two transactions per listed product record. This confirms at least one identifiable buyer relationship, but does not demonstrate a broad or extensive customer base.
