Shenzhen Sunmy Hardware Co.,Ltd. specializes in manufacturing high-precision capillary stainless steel tubes and pipes, offering unparalleled quality for demanding industrial applications. With outer diameters ranging from 1mm to 8mm, these micro-tubular components are engineered for critical systems in medical devices, aerospace, precision instrumentation, and automotive engineering. Acting as your dedicated manufacturing partner, we provide 100% fully customizable OEM and ODM solutions. Whether you require standard straight tubes or complex geometric configurations, our robust development capabilities ensure your exact specifications are transformed into flawless physical products.
Our capillary stainless steel tubes are crafted through a rigorous combination of advanced cold-drawing and Precision CNC Turning processes.
We excel in secondary machining. Using state-of-the-art CNC lathes, we can perform intricate internal and external turning, threading, chamfering, and grooving on micro-tubes with exceptional accuracy.
Beyond basic cutting, our in-house capabilities include precision bending, welding, punching, decoiling, and end-forming.
From raw material selection to final surface treatment, every step is monitored to maintain a strict ±1% tolerance, ensuring perfect concentricity, structural integrity, and a burr-free finish.
