Surface treatment process of medical equipment parts-AbleMed


Surface treatment of medical device parts is a critical process that improves performance, durability, and compatibility with biological tissue by applying different technologies and coatings to the surface of the part. Common surface treatments include anodizing, electroplating, sandblasting, etc. These methods can improve the corrosion resistance, hardness, and even biocompatibility of parts in some cases.

Through the careful selection and application of surface treatment technologies, medical device manufacturers can ensure that parts are more reliable and safe in use, while meeting the high quality and performance requirements of the medical industry. These surface treatment innovations not only help improve the functionality of medical devices, but also provide patients with a safer and more effective medical experience.

Why do medical equipment parts need surface treatment?

The purpose of surface treatment of medical device parts is to improve the material's biocompatibility, corrosion resistance, hardness and wear resistance, adjust electrical capabilities, improve lubricity, enhance appearance, and impart antibacterial and antiviral properties. This comprehensive approach is designed to ensure the reliability and durability of medical equipment in direct contact with the human body or in harsh environments, meet the medical industry's requirements for high quality, high safety and performance, and ultimately promote patient safety and medical experience.


What are the commonly used surface treatments for medical device parts?

Brushing: Using mechanical methods to make elongated textures appear on the surface to improve the appearance and texture.

Polishing: The removal of surface unevenness by mechanical or chemical means, smoothing it and enhancing its luster.

Anodizing: An electrochemical process often used on aluminum parts to increase their corrosion resistance and hardness.

Sandblasting: Use high-speed abrasives to impact the surface to produce uniform and fine unevenness to improve adhesion.

Laser engraving: Use laser to etch the surface of materials to mark fine patterns or text.

Electroplating: Coating a metal surface with a layer of metal to improve conductivity, corrosion resistance and appearance.

Electrophoresis: Depositing coating particles onto the surface of a part through an electric field, achieving uniform coverage.

Chromate: A chemical treatment that improves the corrosion resistance of metal surfaces.

Powder Coating: Spraying powder coating onto a surface creates a uniform coating that improves wear resistance and appearance.

Spray Paint: Use a spray gun to apply liquid paint to protect surfaces and add decorative appeal.


Impact that the medical environment may have on these surface treatment processes:

Surface treatment of medical device parts plays a key role in addressing the unique challenges found in medical environments. In order to reduce the risk of cross-infection, on the one hand, surface treatments need to have excellent antibacterial and antiviral properties; on the other hand, medical equipment needs to be cleaned and disinfected frequently.

The surface treatment must be resistant to strong cleaning agents and disinfectants to ensure that it is not damaged. For equipment that is subject to frequent movement or friction, the surface treatment needs to have wear-resistant properties to maintain its performance and appearance. Considering the temperature and humidity changes that may exist in the medical environment, surface treatment should be able to adapt to these conditions to prevent damage or corrosion and ensure the long-term reliable operation of medical equipment.

To give an example, many medical devices will be sterilized with hydrogen peroxide in a low-temperature plasma environment. At this time, if the aluminum anodized parts are not up to standard due to the process, it will cause discoloration and corrosion of the endoscope parts, thus Impact on the use of medical devices.


How to choose a processing and surface treatment factory for medical equipment parts?

When choosing a medical device parts processing and surface treatment factory, it is recommended to first ensure that it has relevant certifications and qualifications, such as ISO 13485. Focus on the factory's professional experience, equipment and technical level, as well as its quality control system. Understand the factory's production capacity, delivery cycle and cost, and visit the factory if possible to get a more intuitive understanding. Check out reviews and references from other clients, and ultimately make sure to sign a clear contract and necessary confidentiality agreements to ensure a smooth collaboration.

What are the colors of aluminum anodization?

Aluminum anodizing is a surface treatment method that creates a variety of colors by forming an oxide layer on the aluminum surface. Common colors include natural aluminum, black, golden yellow, blue, red, green and purple. The appearance of these colors depends on the thickness of the oxide layer and the dyes introduced during processing. However, in medical use, in order to meet special process requirements, the colors that can be selected will also vary.

What are the aluminum anodizing colors that can achieve low-temperature plasma sterilization with hydrogen peroxide and do not fade?

Because this process is only for the medical industry and the manufacturing process is complicated, there is currently no clear color standard in the industry. Take AbleMed as an example, the colors that can meet the requirements include bright black, matte black, bronze, In addition to the original colors, other colors are also in the development and testing stages.
