  • Supports both prototyping and scalable production for R&D, clinical trials, and commercial medical device manufacturing.
FAQs:
  • What are the key advantages of using 304 stainless steel for medical device components?
    304 stainless steel offers excellent corrosion resistance, high strength, good machinability, and is hygienic and non-magnetic in its annealed state. It provides good biocompatibility for limited or prolonged skin contact, making it suitable for both direct and indirect patient contact applications in medical devices.
  • What level of precision can be achieved with your CNC milling process?
    Our CNC milling process can achieve standard tolerances of ±0.05 mm, precision tolerances of ±0.025 mm, and high-precision tolerances of ±0.0125 mm for critical features. We maintain positioning accuracy up to ±0.005 mm and repeatability up to ±0.0025 mm using advanced multi-axis machining centers.
  • How do you ensure medical-grade cleanliness and sterilization compatibility?
    We perform intensive multi-stage ultrasonic cleaning in validated processes to meet medical cleanliness standards for low particulate count and non-volatile residue. Components are packaged in controlled cleanroom environments and are fully compatible with all standard medical sterilization methods including autoclave, ethylene oxide, gamma radiation, and hydrogen peroxide plasma.
  • What quality certifications and documentation do you provide?
    We operate under ISO 13485:2016 certified quality management system specifically for medical devices. We provide 100% dimensional inspection using CMM and optical comparators, visual inspection reports, material certificates, and full traceability documentation for all materials and processes.
