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.
Preventative Maintenance in Casting Impregnation
In the casting impregnation industry preventative maintenance is a necessity. Due to the nature of the impregnation process and the wet environment, corrosion and equipment failure can occur at a rapid rate if proper maintenance does not take place.
How Can Sealant Get Into a Vacuum Pump?
A common problem for those operating impregnation systems is sealant making its way into a vacuum pump. Sealant inside a pump (Figure 1) will lead to increased maintenance costs; premature pump rebuilds; or early pump replacement resulting from irreparable pump damage. There are multiple ways sealant can end up in the pump.
Maintaining Impregnation Sealant for Optimal Performance
In order to maintain impregnation sealant for optimal performance, there are two vital tests that should be performed on a regular basis:
Dry Vacuum vs Wet Vacuum Process
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.
Why Do Aluminum Castings Discolor During Vacuum Impregnation?
A common question asked by customers is “Why do aluminum castings discolor during vacuum impregnation?”. Aluminum parts with highly machined surfaces are more likely to be affected than those that are cast.
