Vacuum impregnation in metal castings and powdered metal parts refers to the sealing of leaks resulting from porosity. In this post, we will discuss in detail one of the selection variables, the three different types of vacuum impregnation processes.
As we begin a New Year, we want to share our top 5 blog posts of 2012. If you missed any of these articles, be sure to check them out. They include helpful information about vacuum impregnation processes, equipment and maintenance.
Fundamentally, there are two factors that control impregnation results – sealant quality (formulation and working condition) and vacuum (depth of vacuum). Because vacuum is such a critical factor in achieving superior results, a Godfrey & Wing representative will always recommend a DV (or DVP) process over WV when discussing the impregnation of High Value parts.
