The right system for every process

Surface treatment of materials used in medical technology

Titanium and titanium alloys Niobium | nitinol | tantalum | chromium-cobalt alloys | stainless steel

The requirements for medical parts, components and materials are very diverse and complex. The safety and reliability of the materials, manufacturing processes and machine technology used are of great importance in medical technology. In addition, the validation of procedures and processes is playing an increasingly important role.

For the surface treatment of medical parts and components, we offer single tank systems and compact electroplating systems, manually operated or as semi-automatic machines with handling system and PLC control.

Procedure

Realize several processes on our systems.

On our systems, you can implement a wide range of processes that are important for medical technology. Whether electropolishing for stents or anodizing of medical components for better visibility.

Surface finishing for MEdical components

In addition, the validation of procedures and processes is playing an increasingly important role. Metallic heart or dental implants in particular are subject to strict material properties: High mechanical strength, maximum biocompatibility and corrosion resistance. Titanium, niobium or stainless steel have these material properties and are therefore ideal for highly stressed medical parts and components.

Our processes

Color anodizing type III

Medical parts or components made of titanium or titanium alloys are electrochemically anodized with special aqueous electrolytes. The result is a thin, firmly adhering titanium oxide layer that appears colored due to the superimposition of light waves (interference). The color palette of type III anodized surfaces ranges from titanium grey, blue, yellow, magenta to green. The main purpose of anodizing medical parts and components is to improve identification and corrosion protection. The titanium oxide layer has very good electrical insulation and biocompatibility

Grey anodizing type II

In addition to colour anodizing, grey anodizing (acidic or alkaline) can also be carried out in the systems. Type II grey anodizing is preferably used for bone plates, bone screws and bone implants. The process produces even thicker coatings and serves to improve corrosion and wear resistance.

Electropolishing

Electrochemical polishing (electropolishing) and deburring of stainless steel significantly improves the properties of the metallic surface, which has a positive effect on the durability of the individual components. Electropolishing is an electrochemical process for surface removal. The removal is carried out with special aqueous solutions using electricity in the micro range and produces a smooth and shiny surface.
