Secondary Metal Processing

Electropolishing is a crucial step in improving the surface finish of medical components. This process removes surface imperfections and contaminants, providing smoother surfaces that reduce friction and improve biocompatibility.

Benefits:

• Enhanced Corrosion Resistance: Electropolishing improves the corrosion resistance of materials, particularly stainless steel, extending the longevity and reliability of components.
• Smoother, Polished Surfaces: Removes surface imperfections and contaminants, providing friction-reducing surfaces that improve device performance and ease of sterilization.
• High-Polish Finishes: Achieves superior surface finishes for components where standard machining cannot meet strict specifications, such as blood pump parts and fluid-contact surfaces.
• Biocompatibility: Essential for components that come into contact with human tissue, such as stents, surgical tools, and implantable devices, reducing contamination risks and improving overall device safety.

Passivation is used to improve the corrosion resistance of stainless steel and other metals. This chemical treatment removes free iron and other contaminants from the metal’s surface, forming a protective oxide layer.

Benefits:

• Ensures that implants and surgical instruments can withstand long-term exposure to body fluids without corroding.
• Provides a protective barrier that enhances the durability of the device.

To ensure the safety and functionality of medical components, deburring removes sharp edges or imperfections left behind from the manufacturing process. Our surface finishing services further enhance the smoothness and quality of components.

Benefits:

• Critical for minimally invasive surgical instruments, where sharp edges could damage tissue.
• Ensures components are safe for use in delicate procedures.

Titanium etching is a critical secondary finishing step in medical device manufacturing that tailors the surface, rather than the shape, of a metal component. By modifying roughness, chemistry, and cleanliness, it directly influences biocompatibility, implant integration, and long-term performance.

‍

Benefits:

• Enhanced surface cleanliness by removing contaminants such as machining oils, residues, and embedded particles.
• Improves the biocompatibility of implanted medical devices by creating micro- and nano-scale surface roughness.

Ultrasonic cleaning is a precision cleaning process that uses high-frequency sound waves to remove contaminants from metal components. Ultrasonic cleaning is a highly effective, non-invasive way to achieve the level of cleanliness required especially for components with intricate designs.

‍

Benefits:

• Provides a thorough cleaning for complex medical components.
• Removes microscopic contaminants and effectively eliminates oils, polishing compounds, metal fines, and particulates.
