Thermal Cure and Anaerobic Sealant Applications
We often write about the different types of vacuum impregnation systems that are commonly used and how each may be best suited for use when processing a particular type of part. Once you have determined the type of system that is required, you then need to select the appropriate sealant for the system and application.
What is the lifespan of your vacuum impregnation system?
Is it more cost-effective to repair your existing vacuum impregnation equipment or to purchase a new system? There are many factors to consider when making this decision.
Don’t Hesitate to Use Vacuum Impregnation
I often meet with potential customers who are hesitant to implement a vacuum impregnation process for a variety of reasons. In this article, I will discuss the most common reasons as well as provide some explanation as to why and how a vacuum impregnation program can benefit your business.
How Much Does it Cost to Impregnate a Part?
One of the most common questions in vacuum impregnation is how much does it cost to impregnate a part, or in other words, how much sealant will a part consume? Parts consume sealant in two ways as part of the normal vacuum impregnation cycle. The first way that parts consume sealant is that sealant actually […]
What is the sealant consumption with Godfrey & Wing sealants?
At Godfrey & Wing, we are often asked this question and wanted to provide some explanation in this article. Some manufacturers state that sealant consumption is 10 grams per impregnated kilogram. Other manufacturers state 5 grams and some even say less than 2 grams. All of these numbers may be correct.
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.
