316L Stainless Steel Medical Parts: CNC Milling Filling Needle Solutions
The 316L Stainless Steel Capillary Tubing Medical Component CNC Milled Filling Needle is precision-engineered for accurate, sterile liquid transfer in medical, pharmaceutical, and lab settings. Utilizing 316L stainless steel, advanced CNC milling creates a robust needle with a sharp tip, controlled lumen, and custom features, ideal for high corrosion resistance, biocompatibility, and sensitive fluid performance.
• Material Preparation: Certified 316L stainless steel capillary tubing (ASTM A269) cut to precise lengths.
• Precision Tip Machining: CNC Milling and Grinding to create sharp beveled points or blunt polished ends.
• Body Milling: CNC mills flats, grooves, and shoulders for integration with syringe barrel adaptors or Luer locks.
• Internal Lumen Polishing: Electropolish internal bore for Ra ≤ 0.2 µm smooth, non-stick surface.
• Surface Finishing: Electropolishing and passivation for maximum corrosion resistance.
