—— SHOMEA Medical-Grade Stainless Steel Needles ——

1.Medical-Grade Stainless Steel Material

Manufactured from certified 304/316L stainless steel in compliance with ISO 13485 and ASTM F138/F139 standards. The material offers excellent biocompatibility, corrosion resistance, and minimal ion release, ensuring long-term safety for human tissue contact.

2.Precision-Ground Needle Tip

The needle tip is processed using high-precision CNC grinding technology to form a sharp, symmetrical, burr-free cutting edge (as shown in the close-up image). This design reduces penetration resistance, enhances puncture accuracy, and minimizes tissue trauma during clinical procedures.

3.Mirror-Polished Surface Finish

The entire needle body undergoes electrolytic polishing, achieving a surface roughness of Ra ≤ 0.2 μm. The ultra-smooth surface helps reduce protein adhesion and bacterial growth, meets medical cleanliness requirements, and facilitates effective sterilization and reuse (where applicable).

4.High Strength with Superior Toughness

With a tensile strength of ≥ 500 MPa and stable elastic modulus, the needle resists breakage under bending or torsion. It withstands repeated punctures and positioning operations, ensuring reliability and safety during surgery or treatment.

5.Standardized Dimensions & Tight Tolerances

Needle diameter, length, and taper are strictly controlled to medical industry standards, with tolerances within ±0.01 mm. This ensures perfect compatibility with syringes, catheters, biopsy guns, and other matching devices.

6.SHOMEA Brand Quality Assurance

Backed by a professional medical consumables R&D team and ISO-certified production lines, SHOMEA implements strict quality control from raw materials to finished products. We also offer OEM/ODM customization services to help medical institutions improve efficiency and reduce operational risks.
