Product Overview

CNC Milling Of Stainless Steel Medical Parts

Product Application:
These are precision-crafted, sterile or cleanroom-ready metal parts that serve as critical structural and functional elements within a wide array of medical devices and equipment.

Surgical Instruments: Jaws, handles, shafts, and ratchets for forceps, needle holders, retractors, and bone cutters.
Implantable Device Housings & Hardware: Caps, covers, enclosures, and custom screws for pacemakers, neurostimulators, drug pumps, and orthopedic implants.
Diagnostic & Monitoring Equipment: Sensor mounts, probe housings, chassis components, and interface plates for imaging systems, analyzers, and patient monitors.
Drug Delivery Systems: Precision manifolds, valve bodies, pump components, and connectors for infusion pumps and inhalers.
Laboratory Automation: Robotic end-effectors, sample tray components, and fluidic blocks for automated diagnostic and research instruments.

Detailed Description:
Specializing in the high-precision CNC milling of medical-grade stainless steel components. Starting from certified raw material (typically 304, 316, or 316L stainless steel), we utilize advanced multi-axis CNC machining centers to produce parts with exceptional dimensional accuracy, complex geometries, and superior surface finishes. This process is ideal for creating prototypes, low-to-medium volume production runs, and replacement parts where off-the-shelf solutions are unavailable.

Frequently Asked Questions

1. What materials are primarily used for these medical parts?

We primarily use medical-grade stainless steel, specifically 304, 316, and 316L (UNS S31603). 316L is the industry standard for implants and harsh medical environments due to its superior corrosion and pitting resistance.

2. What level of precision can be achieved via CNC milling?

Our standard dimensional tolerance is ±0.025 mm. For critical mating or functional features, we can achieve high-precision tolerances of ±0.0125 mm (±0.0005").

3. Are these parts compatible with standard medical sterilization methods?

Yes, all parts are processed to be fully compatible with standard sterilization methods, including Steam Autoclave, Ethylene Oxide (EtO), and Gamma Radiation.

4. What secondary surface treatments do you provide?

We offer mandatory passivation per ASTM A967 to restore corrosion resistance. Additional finishes include electropolishing for superior cleanability, sandblasting for a matte finish, and precision grinding.

5. Do the parts come with material and quality documentation?

Every shipment includes a Device History Record (DHR) package containing Mill Test Certificates, dimensional inspection reports (CMM), passivation certificates, and a Certificate of Conformance.

6. Which quality management certifications do your facilities hold?

The manufacturing facility is certified under ISO 9001:2015 for general quality management and ISO 13485:2016 specifically for medical device quality management systems.
