Shomea Customizable Stainless Steel Leak-Proof Inkjet Needle for High-Precision Printing

Yes, this is the core advantage of our product. Every needle must pass dual leak tests before shipment: a high-pressure air decay test (0.5MPa) followed by spot-check helium mass spectrometry. We guarantee zero penetration and zero bubbles at the needle body and weld joints, ensuring no ink backflow or air mixing during printing.

Not at all. Despite the micro-diameter, we utilize a special anti-breakage reinforcement process that significantly enhances the material's toughness and fatigue strength. Compared to standard needles, ours resist snapping under lateral force and offer better resilience, making them ideal for frequent industrial operations.

Absolutely! We use high-precision laser welding technology to fuse the needle and base into one solid piece, rather than simple gluing or crimping. The weld strength exceeds the tensile strength of the needle itself and is verified by leak tests, making it safe for high-pressure environments.

We default to 304 or 316L medical-grade stainless steel, which offers excellent corrosion resistance. Rusting will not occur under normal industrial conditions unless exposed to strong acids or alkalis for extended periods. Custom materials are available upon request for special anti-corrosion needs.

We support full customization. While the image shows a standard model, we can customize the base thread specifications (e.g., M5, M6, 1/4"-28), needle length, tip angle, and step dimensions according to your drawings or samples. Just provide your requirements, and we will match them.
