316L Stainless Steel CNC Milling Biocompatible Capillary Tube Filling Needle for Medical Applications 0
Product Overview
This precision medical filling needle utilizes 316L stainless steel capillary tubing and advanced CNC milling to create an integrated assembly with sharp, precise tip, controlled internal lumen, and custom external features. Designed for applications requiring high corrosion resistance, biocompatibility, and reliable performance with sensitive fluids.
Manufacturing Process
  • Material Preparation: Selection and cutting of certified 316L stainless steel capillary tubing (ASTM A269) to precise length
  • Precision Tip Machining: Micro-machining techniques to create sharp beveled points, blunt polished ends, or specialized geometries
  • Body/Feature Milling: CNC milling of flats, grooves, shoulders, or mounting features for assembly integration
  • Hub/Connector Fabrication: Machining and permanent attachment of hubs via laser welding, press-fitting, or adhesive bonding
  • Internal Lumen Polishing: Electropolishing of internal bore for smooth, non-stick fluid flow
  • Surface Finishing: Full component electropolishing and passivation for maximum corrosion resistance
  • Cleaning & Sterilization: Ultrasonic cleaning and validation for Gamma irradiation or Ethylene Oxide sterilization
  • Functional Testing: Flow rate verification, leak testing, and tip sharpness assessment
Applications
  • Pharmaceutical aseptic filling of vials, syringes, or cartridges
  • In-Vitro Diagnostics (IVD) sample probes and reagent dispensers
  • Microfluidic device interfaces and connections
  • Laboratory automation and liquid handling robots
  • Medical device drug delivery systems
  • Medical-grade adhesive and sealant dispensing
