As a professional advanced manufacturing service provider, Guanding Model Technology Co., Ltd. offers targeted passivation solutions for medical device metal components, perfectly fitting the "More Solutions" positioning to meet the strict quality and compliance requirements of the medical industry. Our medical-grade passivation process forms a dense, inert protective film on the metal surface through chemical reactions, effectively enhancing corrosion resistance, preventing metal oxidation, and ensuring the components meet medical-grade biocompatibility and cleanliness standards.


We specialize in medical-grade passivation for metal components (primarily stainless steel, titanium alloys and their alloys), adopting medical-compliant passivation solutions and processes that fully comply with ISO 13485 standards and medical biocompatibility requirements. Our passivation services feature uniform protective film, stable performance, no damage to component dimensions, and strong adaptability to complex-shaped components, suitable for medical device parts such as surgical instruments, implantable components, diagnostic equipment accessories, and medical hardware that require high corrosion resistance and biocompatibility.


Our experienced engineering team follows DFM principles and medical manufacturing norms to optimize passivation parameters, including passivation solution concentration, processing temperature, and immersion time, ensuring the protective film meets medical-grade corrosion resistance and cleanliness standards. We implement full-process quality control, including film thickness testing, corrosion resistance testing, biocompatibility verification, and passivation layer adhesion testing. With one-stop service from pre-treatment (degreasing, pickling) to passivation and post-drying, we help medical device customers obtain high-quality, compliant metal components with excellent corrosion resistance and long service life.
