Explore our core engineering capabilities in stainless steel precision casting, custom non-standard CNC turning, titanium milling, and multi-axis complex machining engineered for rigorous biomedical and industrial applications.
Navigating tight tolerances, biocompatibility standards, and strict zero-defect manufacturing in modern healthcare systems.
Medical machined parts require strict adherence to certified materials such as Titanium Grade 5 (Ti-6Al-4V ELI), Implant-Grade 316L Stainless Steel, PEEK, and Nitinol. Chemical stability and resistance to physiological corrosion are non-negotiable parameters for surgical and diagnostic devices.
With surgical robotics and minimally invasive endoscopic devices scaling down, dimensional tolerances regularly reach ±0.002mm (2 microns). Achieving such repeatabilities demands state-of-the-art Swiss-type turning, 5-axis CNC micro-milling, and thermal-controlled machining environments.
Under international standards including ISO 13485, FDA 21 CFR Part 820, and EU MDR compliance, custom medical hardware demands complete batch material traceability, full CMM dimensional inspection protocols, and certified cleanroom passivation.
Integrating turn-mill composite machining, high-precision investment casting, and automated quality control pipelines.
Complex surgical components, such as joint replacement trial implants and internal housing for arthroscopic devices, require multi-axis simultaneous machining. Our 5-axis CNC centers eliminate multiple setups, maintaining geometrical alignment across complex organic surfaces while achieving Ra 0.2 µm micro-finishes without manual polishing.
Ideal for slender, high-aspect-ratio medical components such as bone screws, spinal rods, and vascular catheter drivers. By utilizing sliding headstock machinery equipped with live tooling, turning and transverse milling are performed in a single clamping cycle, eliminating concentricity errors and delivering volume batch consistency.
Combining soluble wax investment casting with secondary precision CNC finishing enables economical production of complex metallic housings, structural valve bodies, and custom marine/medical brackets. Casting allows optimized structural weight, while subsequent CNC machining guarantees critical sealing surface flatness within ±0.005mm.
Machined medical parts undergo rigorous post-processing including citric/nitric acid passivation according to ASTM A967 to build a stable chromium oxide corrosion barrier. Ultrasonic solvent degreasing and micro-deburring under high magnification ensure no microscopic metallic particulate compromises patient safety.

Expert answers regarding custom medical component manufacturing, material selection, quality control, and order logistics.
Material selection depends heavily on whether the component is implantable or non-implantable. For implantable applications, Titanium Grade 5 (Ti-6Al-4V ELI) and 316L Stainless Steel are primary choices due to their excellent biocompatibility, corrosion resistance, and high strength-to-weight ratio. For diagnostic housings or non-implantable instruments, high-performance engineering plastics like PEEK and anodized aluminum alloys (6061/7075) are frequently specified.
We combine high-rigidity 5-axis CNC machining centers and Swiss-type lathes with specialized cutting tools designed specifically for titanium alloys. Machining parameters, cutting fluid concentration, and thermal expansion are tightly controlled. Every part undergoes full CMM measurement and optical verification in temperature-controlled quality labs prior to shipment.
We provide full-spectrum finishing services, including citric and nitric acid passivation (per ASTM A967), electropolishing to reach ultra-smooth Ra finishes, bead blasting, micro-deburring under high magnification, anodizing (Type II and Type III Hardcoat), laser marking, and ultrasonic cleaning for particulate-free shipment.
Investment casting is optimal for producing complex, near-net-shape metal parts with minimal material waste, making it ideal for valve bodies and complex housings. CNC machining delivers extreme sub-micron tolerances and high surface finishes from solid stock. We often combine both processes: casting the overall geometry and CNC machining critical mating faces and threaded features.
Fast-track CNC prototypes can be completed in as little as 3 to 7 working days. Investment casting tooling and initial sample approval usually take 2 to 4 weeks depending on geometry complexity. Once samples are approved, scalable volume production lines deliver consistent shipments according to your scheduling needs.
