The Coating Formation Efficiency of the METALAST Anodizing Processes

From METALAST International, Inc.
 

 
The coating formation efficiency of the METALAST anodizing processes for a variety of aluminum alloys is summarized in both tabular and graphic forms in this report. It is obvious that the METALAST technology is able to doubly enhance the production efficiency of anodizing processes, in comparison with traditional anodizing processes. In particular, some die casting alloys with high silicon content, which are hardly anodized in traditional anodizing processes, can efficiently be processed with the METALAST technology in both Type II and Type III anodizing. In addition, each alloy can be anodized to produce a targeted thickness of the ceramic coating on its surface with a tight tolerance at a selective current density with the METALAST technology, which provides anodizers with full flexibility in production arrangement and consistent quality assurance. These results can help anodizers understand the superiority of the METALAST technology in anodizing production. Production efficiency is one of major issues any manufacturers are concerned about. For the traditional anodizing processes under constant voltage control, the production is usually quite inefficient.
