Stainless Steel Microneedle by ZorayPT

ZorayPT’s stainless steel microneedle (Model ZPT-SMN-004) is a robust, high-durability platform built from premium medical-grade 304 or 316L stainless steel, offering exceptional strength, corrosion resistance, and precision for demanding transdermal applications in sensing, delivery, and cosmetic therapies. This stainless steel core ensures structural integrity under repeated stress, making it the foundation of choice for long-term implantable sensors or high-volume production devices. As a leading one-stop OEM/ODM manufacturer with full in-house plastic molding, metal processing, CNC machining, and coating capabilities, we produce superior quality stainless steel microneedles with diameters ranging from 30G to 36G (0.13mm to 0.30mm, customizable) to achieve the optimal balance of penetration ease and mechanical reliability.

Our leading coating technology overlays gold, platinum, palladium, or silver (customizable, including nickel-free options) on the stainless steel base, enhancing conductivity, biocompatibility, and antimicrobial performance while preserving the material’s inherent toughness. Solid stainless steel microneedles are ideal for electrochemical electrodes and contact-style sensing in rugged biosensing environments, while hollow variants support micro-sampling or fluid transfer in pharmaceutical and industrial monitoring. The ultra-sharp tip and polished shaft minimize insertion force and tissue trauma, ensuring repeatable, low-pain performance across diverse applications.

Each stainless steel microneedle is manufactured under ISO 13485-certified conditions in a Class 100,000 cleanroom, undergoing full magnification inspection for coating adhesion, tip sharpness, and dimensional accuracy. Customizable tip shapes (tapered, flat, round) and array layouts enable adaptation to specific needs—from single-needle probes for industrial sensors to multi-array patches for wearable health devices. The stainless steel construction withstands sterilization cycles and environmental exposure, offering extended service life compared to softer materials.

ZorayPT’s all-in-house capabilities enable rapid customization, from material grade (304 for cost-efficiency or 316L for superior corrosion resistance) to plating schemes, aligning with client requirements for CGM, industrial process monitoring, or cosmetic delivery systems. The durable stainless steel core reduces breakage risks in high-throughput production, delivering economic benefits through lower failure rates. With faster lead times and cost-efficient production, ZorayPT supports global brands in developing reliable, high-performance microneedle solutions. Whether for harsh industrial sensing or sensitive biomedical applications, the ZPT-SMN-004 stainless steel microneedle provides the strength, precision, and customization needed for mission-critical performance.
