316L Stainless Steel Capillary Tube Medical Parts CNC Milling Filling Needle

Precision-engineered 316L stainless steel capillary tubing component with CNC-milled features for accurate, sterile liquid transfer in medical, pharmaceutical, and laboratory applications.

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
