Advantages of choosing JupaiCNC for Medical components

Through ISO 9001 and ISO 13485 certification, relying on five-axis ultra-precision machining technology, combined with medical grade titanium alloy (Ti-6Al-4V ELI), cobalt-chromium alloy and biocompatible materials such as PEEK, the processing accuracy of key implants is up to ±0.005mm, and through nano-level electrolytic polishing and passivation treatment, surface roughness can reach to Ra≤0.1μm. Through stress optimization and microdefect control technology make the component life of more than 15 years, the defect rate < 0.005%.

JupaiCNC provides technology support for Medical

5-axis linkage precision machining ‌ ‌
5-axis CNC technology is used to realize the machining of complex three-dimensional structures such as artificial joints and dental implants. The tolerance control is ±0.005mm‌.‌

Special materials can be processed ‌ ‌
Suitable for medical materials such as titanium alloy (Ti-6Al-4V ELI), cobalt-chromium alloy and PEEK, electrolytic polishing to achieve Ra≤0.1μm ultra-clean surface, biocompatibility in line with ISO 10993‌68.

The whole process sterilization traceability ‌ ‌
Through high pressure steam sterilization and four-level gas seal verification, with laser marking to achieve lifetime traceability of production parameters.

Common materials and properties of Medical equipment parts

Stainless steel

Martensitic stainless steel ‌ (such as 4Cr13) : high hardness, used for surgical scissors, bone forceps and other cutting instruments

Polyvinyl chloride (PVC) ‌

Rigid/flexible optional, anti-microbial, used in blood bags, dialysis lines ‌.

Polycarbonate (PC) ‌

High transparency, impact resistance, support high temperature sterilization, suitable for transparent instrument housing and observation window ‌

Polyether ether ketone (PEEK)

High temperature resistance (250℃), excellent biocompatibility, used for orthopedic implants and cardiovascular stents and other high-end devices ‌

ABS plastics ‌

Impact resistant, easy to process, used for equipment shell; Glass fiber reinforced for increased mechanical strength ‌

Titanium alloy ‌ (e.g. Ti-6Al-4V)

Excellent biocompatibility, corrosion resistance, high strength and low density, widely used in orthopedic implants (artificial joints, spinal screws) and cardiovascular stents ‌

JupaiCNC provides surface treatments for Medical device parts

Anodizing ‌

Titanium alloy surface oxide film (such as heart pacemaker shell), improve corrosion resistance and biocompatibility ‌.

Plasma treatment

To enhance the surface activity and adhesion of materials, suitable for polymer devices (e.g. dialysis lines) ‌

Ultrasonic cleaning

Combined with high temperature sterilization ensures sterility of complex structural instruments such as endoscopes

Mechanical/electrolytic polishing

Eliminate burrs and micro-cracks, electrolytic polishing can reduce surface roughness to Ra 0.03μm, reduce the risk of bacterial growth (bone nails, surgical forceps commonly used)‌

Heat Treatment‌

Enhances material properties like hardness and wear resistance ‌
