Product Description
316L Stainless Steel Electroplating Polishing CNC Milling Metal Beauty Needle
Product Overview
The 316L Stainless Steel Plated and Polished CNC Milled Metal Beauty Needle is a high-end, precision-crafted aesthetic instrument. It combines the biocompatibility and corrosion resistance of medical-grade 316L stainless steel with advanced manufacturing and finishing techniques. The core needle structure is precision machined via CNC milling for exact dimensions and geometry, then undergoes specialized plating and high-gloss polishing to achieve a flawless, mirror-like finish.
Manufacturing Process
- CNC Milling of 316L Substrate: Precision machining from solid 316L stainless steel rod using high-precision CNC milling centers or Swiss lathes
- Pre-Plating Surface Preparation: Rigorous cleaning, precision polishing, ultrasonic cleaning, and electrocleaning for perfect plating adhesion
- Specialized Electroplating: Electrochemical process with options including 24K Gold, Titanium Nitride (TiN), Zirconium Nitride (ZrN), or Rhodium plating
- Post-Plating Precision Polishing: Multi-stage mechanical polishing with progressively finer abrasives to achieve mirror finish (Ra < 0.025 µm)
- Sterilization-Prep Finishing: Final ultrasonic cleaning in deionized water and medical-grade solvents with cleanroom packaging
- Quality Inspection: 100% visual inspection, dimensional checks, and adhesion testing per ASTM standards
Applications
- High-End Microneedling (Dermarolling/Dermastamping)
- Mesotherapy & Bio-Revitalization
- Permanent Makeup & Microblading
- Thread Lifting Procedures
- Luxury Acupuncture & Traditional Medicine
Technical Specifications
| Category | Parameter | Specification / Details |
|---|---|---|
| Core Material | Substrate | 316L Stainless Steel (UNS S31603, 1.4404) - Medical Grade, Vacuum Melted optional |
| Plating & Coating | Plating Types | 24K Gold (Au), Titanium Nitride (TiN - PVD), Zirconium Nitride (ZrN - PVD), Rhodium (Rh) |
| Plating Thickness | 0.5 µm - 2.5 µm (Standard range. Gold typically 1.0-1.5µm) | |
| Adhesion Standard | Passes ASTM B571 bend test or equivalent | |
| Key Plating Benefits | Gold: Hypoallergenic, noble finish. TiN/ZrN: Extreme hardness (~80+ HRC equivalent), wear-resistant. Rhodium: Brilliant white, anti-tarnish | |
| Dimensions & Geometry | Needle Gauge (OD) | 32G (0.23mm), 34G (0.18mm) for fine needles; 30G (0.30mm) common for microneedling. Custom diameters |
| Length (Exposed) | 0.25mm, 0.5mm, 1.0mm, 1.5mm, 2.0mm (for microneedling); up to 10-40mm for other applications | |
| Tip Geometry | Lancet Point (sharp), Chisel Point (for microblading), Multi-tip configurations (e.g., 5, 9, 12 needles clustered) | |
| Surface Finish | Final Polish Grade | Mirror Polish. Surface Roughness (Ra) < 0.025 µm |
| Gloss Level | High specular reflectance | |
| Performance | Primary Function | Precise, low-trauma skin penetration for delivery or stimulation |
| Sharpness | Surgical-grade sharpness, maintained post-plating and polishing | |
| Corrosion Resistance | Exceptional. 316L substrate + noble metal plating provides maximum protection | |
| Durability | Plating (especially TiN/ZrN) significantly increases surface hardness, extending usable life | |
| Biocompatibility & Safety | Overall Biocompatibility | 316L substrate and specified platings (Au, Rh, TiN) are biocompatible per ISO 10993-1 |
| Nickel Release | 316L has low nickel content; noble metal plating forms complete barrier for nickel-free patient contact | |
| Sterilization & Packaging | Sterilization Compatibility | Compatible with all standard methods: Autoclave, Dry Heat, Gamma Irradiation, ETO, Low-Temperature Plasma |
| Packaging | Individually blister packed in sterile barrier for single-use, or in sterile/non-sterile racks for reusable devices | |
| Quality Assurance | Inspection | 100% visual for polish/plating defects under 10x-30x magnification. Dimensional sample testing |
| Plating Tests | Thickness (XRF), Adhesion (tape/bend test), Porosity (ferroxyl test for nickel barrier) | |
| Certification | Material Certs (3.1), Plating Process Certs, Biocompatibility test reports available upon request | |
| Regulatory | Manufactured under ISO 13485 quality system. Supports FDA and CE MDR documentation |
