Precision Anodizing Services for Medical Implants & Instruments
Biocompatible Oxide Coatings for Titanium & Aluminum
Our advanced anodizing processes enhance surface hardness, reduce friction, increase wear resistance, and enable precise color-coding for complex surgical tray identification and implant differentiation.
- Titanium Anodizing Type II (AMS 2488): Superior wear resistance and anti-galling performance for orthopedic implants
- Titanium Anodizing Type III: Vivid spectrum color anodizing for immediate surgical instrument identification
- Aluminum Anodizing Type II: Class 1 (Clear) and Class 2 (Color) architectural and surgical case coatings
- Aluminum Anodizing Type III: Hard-coat anodizing for high-durability sterilizable medical hardware
ASTM A967 Compliant Chemical Passivation
Maximum Corrosion Resistance & Decontamination
Machining processes can embed free iron and microscopic impurities on stainless steel surfaces. Paragon Medical utilizes automated, highly repeatable passivation systems to restore pure chromium oxide protective layers across all critical device geometries.
- Nitric & Citric Passivation: Fully validated to ASTM A967 standards for surgical stainless steels
- Nitric 3 Treatment: Specialized formulations for internal channels of tubular surgical instruments
- Multi-Stage Cleanings: Aqueous degreasing, vapor cleaning, and ultrasonic contaminant removal
- Verified Quality Assurance: High-humidity and copper sulfate testing for complete corrosion safety
Ultra-Precision Electropolishing & Micro-Deburring
Achieving Sub-Micron Smoothness & Surface Purity
Our electropolishing services utilize controlled electrochemical baths to precisely remove microscopic surface peaks (20 to 40 micron removal accuracy). This process eliminates microscopic burrs, rounds sharp edges, and yields an ultra-smooth, mirror-like passive surface optimal for blood and tissue contact.
- Micron-Level Tolerances: Controlled material removal within 20–40 microns for tight-tolerance medical parts
- Micro-Burr Removal: Eliminates stress-concentration points and sharp edges on complex implants
- Enhanced Biocompatibility: Reduces surface roughness (Ra), minimizing bacterial adhesion
- Dual Surface Benefit: Combines superior aesthetic shine with enhanced chemical passivation
FDA & EU MDR Compliant Laser Marking & UDI Etching
Permanent, High-Contrast Marking for Global Regulatory Compliance
Meeting global Unique Device Identification (UDI) regulations requires sharp, permanent marking that resists degradation over hundreds of autoclave sterilization cycles. Paragon Medical provides high-precision laser marking for serial numbers, logos, and high-density GS1 2D DataMatrix barcodes.
- UDI / GS1 Barcode Etching: 2D DataMatrix barcodes engineered for high readability
- Passivation-Resistant: Markings remain dark and legible after aggressive chemical passivation
- Autoclave Durable: Resistant to repeated steam sterilization, cleaning, and chemical cycles
- Non-Destructive Etching: Preserves structural integrity of delicate medical device walls
