Key Advantages

Advantages of CNC Machining for Medical Products

In medical technology, where hygiene, precision and mechanical reliability are non-negotiable, we have developed a full range of CNC machined solutions tailored to the unique demands of medical applications.

Biocompatible Materials

316L stainless steel and Ti-6Al-4V ELI titanium are non-toxic, hypoallergenic and suitable for long-term contact with the human body.

Materials are verified with mill certificates and tested for corrosion resistance to support medical device approval.

Corrosion Resistance

Medical-grade 316L offers outstanding resistance to body fluids, saline and common sterilants, keeping surfaces stable over years of service.

Passes 96-hour salt spray testing, with options for electropolishing to remove micro-burrs and enhance cleanability.

Mirror-Finish Surfaces

Our signature stainless steel mirror finishing reaches Ra 0.2um (8K mirror), eliminating bacteria-harboring roughness.

High-gloss, defect-free, fingerprint-resistant surfaces make cleaning and inspection faster and safer.

Precision & Repeatability

CNC turning and turn-mill combination hold tolerances of +-0.005mm with high concentricity for moving and sealing components.

100% inspection with data traceable to each batch, machine and operator.

Manufacturing Capability

Medical-Grade CNC Machined Components

From single prototypes to 500,000 parts per month, we machine a complete range of medical device components.

Custom Solutions

Customized CNC Machining Solutions for the Medical Device Industry

We provide full customization from concept design to mass production. Our engineering team works closely with customers to ensure every component meets the strict standards of the medical industry.

Surface cleanability

Pain point:Rough machined surfaces trap bacteria and make sterilization difficult.
Solution:Mirror finishing to Ra 0.2-0.6um plus electropolishing removes micro-burrs and creates easy-to-clean surfaces.

Material traceability

Pain point:Medical devices require documented material origin and composition.
Solution:Mill certificates for every batch of 316L and titanium, with full batch traceability through production.

Sterilization resistance

Pain point:Components must survive repeated autoclave and chemical sterilization.
Solution:Corrosion-resistant alloys and surface treatments validated for repeated sterilization cycles.

Multi-functional integration

Pain point:Modern devices combine sensors, seals and moving parts in one compact assembly.
Solution:Turn-mill combination machining produces complex integrated profiles in a single setup, reducing joints and failure points.

Small-batch piloting

Pain point:Traditional factories require high MOQ, blocking new product development.
Solution:0 MOQ prototyping with 3-day sample delivery, then flexible scale-up to mass production.
