Product Description

CNC Medical Parts: Stainless Steel Capillary Tube Filling Needle Solutions

The 316L Stainless Steel Capillary Tubing Medical Component CNC Milled Filling Needle is precision-engineered for sterile liquid transfer, dispensing, or micro-dosing in medical, pharmaceutical, and lab settings. Made from 316L stainless steel capillary tubing, it undergoes advanced CNC milling to produce a robust needle with a sharp tip, controlled lumen, and custom features.

Manufacturing Process

Material Preparation: Certified 316L stainless steel capillary tubing (ASTM A269).
Precision Tip Machining: CNC Milling/Grinding for sharp beveled points or blunt polished ends.
Body Feature Milling: CNC milling of flats, grooves, and shoulders for integration.
Internal Lumen Polishing: Electropolished internal bore (Ra ≤ 0.2 µm) for smooth flow.
Surface Finishing: Full electropolishing and passivation for corrosion resistance.
Cleaning & Sterilization: Ultrasonic cleaning, compatible with Gamma or EtO sterilization.

Frequently Asked Questions

What materials are used for the medical filling needles?

We primarily use 316L Stainless Steel (ASTM A269), which is low carbon and offers superior corrosion resistance and excellent biocompatibility compliant with ISO 10993.

Can the needle dimensions be customized?

Yes, the outer diameter (OD), inner diameter (ID), overall length, and tip geometry are fully customizable to meet specific medical or laboratory requirements.

What is the surface finish quality of the needles?

The internal lumen is electropolished to Ra ≤ 0.2 µm, and the external surface is electropolished and passivated to Ra ≤ 0.4 µm, ensuring smooth flow and easy cleaning.

What quality certifications does your production process follow?

Our production is certified under ISO 9001:2015 and ISO 13485:2016, specifically for medical device hardware and precision components.

Are these needles suitable for high-pressure applications?

Yes, due to the high strength of 316L stainless steel, these needles are suitable for high-pressure dispensing, often exceeding 100+ bar.

What sterilization methods are compatible with these parts?

Our products are validated for both Gamma Irradiation (25 kGy) and Ethylene Oxide (EtO) sterilization methods.
