304 316L Stainless Steel Capillary Tube; Seamless Tube; Laser Slot Micro-Hole Processing

Product Description

We specialize in the precision manufacturing of 304 and 316L Stainless Steel Capillary and Seamless Tubes, enhanced with advanced Laser Slotting and Micro-Hole Machining. Our products are engineered for applications demanding ultra-precise fluid conveyance, gas flow, instrumentation, and miniaturized components.

The use of 304/316L stainless steel provides excellent corrosion resistance, high strength, and durability. The laser machining process offers a burr-free, heat-controlled, and highly accurate method for creating complex micro-features on these small-diameter tubes without inducing significant mechanical stress, making them ideal for critical use in medical, semiconductor, and analytical industries.
