DongGuan YuanYi Hardware Products Co., Ltd. is a professional manufacturer with over 13 years of experience in CNC precision machining. Located in Dongguan-the hub of global manufacturing-YuanYi specializes in custom and non-standard machining services for international OEM and ODM customers.
We provide precision-engineered metal and plastic components to various industries including automation, machinery, automotive, aerospace, robotics, medical devices, renewable energy, industrial automation, semiconductor, telecommunications, and consumer electronics. With solid technical expertise and modern production facilities, we support customers from product development to mass manufacturing.
YuanYi offers comprehensive CNC machining services to handle diverse projects and complex requirements. Our capabilities include CNC turning, CNC milling (3-axis, 4-axis, 5-axis), 5-axis CNC machining with 600 × 600 × 400 mm travel, mill-turn compound machining, Swiss-type machining, gantry CNC machining, rapid prototyping, and flexible production from low-volume to large-scale manufacturing. Whether for one-off prototypes or full production runs, we deliver tailor-made machining solutions with precision and efficiency.
Precision is the foundation of our manufacturing. YuanYi achieves machining accuracy up to ±0.005 mm, grinding accuracy up to ±0.002 mm, and surface roughness as fine as Ra0.4 μm, while maintaining parallelism, verticality, and concentricity within ±0.005 mm. These capabilities enable us to deliver high-precision CNC parts for industries where reliability and accuracy are critical, such as aerospace, medical, robotics, and semiconductor manufacturing.
YuanYi ensures product quality with advanced inspection and testing equipment, including spectrometer for material analysis, Hexagon 3D CMM for complex dimensional inspection, 2D projector for contour measurement, Tesa height gauge, Rockwell hardness tester, surface roughness tester, and Mitutoyo gauges including micrometers, calipers, plug gauges, ring gauges, and thread gauges. We perform 100% inspection on critical dimensions to ensure precision, consistency, and reliability.
We operate under strict international standards, certified with ISO 9001: 2015 Quality Management System and ISO 14001: 2015 Environmental Management System. We integrate lean production and sustainable manufacturing to guarantee high-quality output while reducing environmental impact. Our vertical management system controls every stage-from material sourcing and CNC machining to surface finishing and packaging-delivering cost efficiency and shorter lead times.
We understand the importance of speed in competitive markets. With strong process control and in-house scheduling, we offer prototypes in 3-5 days, small batches in 5-7 days, and medium to large-scale production in 15-30 days. This flexibility helps customers accelerate development cycles and shorten time-to-market.
YuanYi provides complete end-to-end support. We offer DFM (Design for Manufacturability) feedback, material selection guidance, process optimization and cost control, technical support throughout production, and seamless communication with timely updates. With one-stop CNC machining service, customers can reduce management workload and ensure smooth, high-quality manufacturing from start to finish.
We are committed to being your trusted OEM/ODM CNC machining partner. With over 13 years of experience, full capabilities from 3/4/5-axis milling, CNC turning, Swiss-type, gantry and mill-turn machining, high precision and advanced inspection, ISO-certified quality, fast lead times, vertical management, and professional technical support, YuanYi delivers precision, reliability, and efficiency.
