Vacuum Impregnation Economics
The primary purpose of vacuum impregnation is to seal porous castings and prevent leakage. If the impregnation process is not efficient and fails to seal the casting it will become scrap, and the number and value of these failures will determine the economic viability of the process.
Top 5 Vacuum Impregnation Blog Posts in 2012
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.
How Can Vacuum Impregnation Pumps Be Protected From Sealant?
In an earlier blog article, we discussed the most common ways that sealant can get into vacuum pumps during the impregnation process.As a reminder, the list included: The transfer valve no longer functions as designed, typically caused by wear and tear over time. This leads to a leaking valve during the vacuum cycle and the […]
How Does Vacuum Impregnation Work?
Vacuum impregnation seals the porosity in metal castings, thus making leaky castings pressure tight. But how exactly does it work? The following demonstrates the 4 steps to the vacuum impregnation process.
Why do I need to impregnate more than once?
There are a couple of possibilities that would require a double cycle impregnation.
What’s the Difference in Anaerobic & Thermal Cure Sealants?
In the vacuum impregnation industry one of the more frequent topics of discussion surrounds the difference between anaerobic and thermal curing impregnation sealants. It is well known that thermal cure sealants, like Godfrey & Wing’s 95-1000A and 95-1000AA, are more widely used than anaerobic sealants (95-1000AC and ACP). Many will say the reasons for the […]
Flocculation: Causes and Prevention in Vacuum Impregnation Process
In an aqueous environment small insoluble particles are kept in solution by physical forces. While temperature and velocity play important roles in solution stability, electrokinetic force is the biggest contributor. Most solids suspended in water possess negative charge. Because particles with similar charges repel each other, those particles with like charges choose to remain in […]
Old vs New Vacuum Impregnation
The other morning I was walking the dog around 5:00 AM, and I noticed how exceptionally crisp and brilliant the stars were in the pre dawn sky, shining though the high pressure system overhead. While finishing the walk around the neighborhood, I thought about mankind’s worldview that the earth was flat as recent as 600 […]

Maquila Industry in Mexico Today
Maquiladoras or Maquila is a word used to describe manufacturing operations in a free trade zone – typically a company that processes components imported into Mexico and then exports the components back to the company’s headquarters in another free trade country.
