Medical-grade Stainless Steel
Material Composition: Select stainless steel materials that comply with international medical standards, such as S31673. This material contains a high proportion of chromium and nickel, which can form a dense oxide film, significantly enhancing its corrosion resistance.
Biocompatibility: It has undergone strict biocompatibility tests to ensure that it is non-toxic, non-irritating, and non-allergenic to human tissues.
Corrosion Resistance: It exhibits excellent corrosion resistance in various physiological environments, such as human body fluids, blood, etc.
Electrolytic Passivation Process
Process Principle: Through an electrolytic reaction, a dense oxide film is formed on the surface of the stainless steel, isolating the metal from the external environment, thereby improving its corrosion resistance.
Surface Treatment: The surface after electrolytic passivation has a high degree of smoothness, with no microscopic burrs or residual impurities, further improving the surface quality of the product.
Raw Material Procurement
Strictly screen stainless steel materials that meet medical standards to ensure the quality of raw materials.
Conduct chemical composition analysis and mechanical property testing on raw materials.
Die Casting Molding
Use high-precision die-casting equipment to ensure product dimensional accuracy and surface quality.
Adopt advanced mold design to meet the complex structural requirements of bone screws.
Electrolytic Passivation Treatment
Immerse the die-cast bone screws into the electrolytic cell to form a dense passivation film through the action of electric current.
Strictly control the composition, temperature and treatment time of the passivation solution to ensure the passivation effect.
Quality Inspection
