Cost of Vacuum Impregnation

Posted by Andy Marin on Wed, Nov 03, 2021 @ 09:29 AM
Manufacturers are constantly faced with either scrapping castings that leak or sealing the castings through vacuum impregnation. Some may perceive vacuum impregnation as a non-value added cost and assume it is less expensive to scrap die castings that leak. In this simplified yet real-world example, we will review the costs of die casting scrap compared to vacuum impregnation.

Sealing Electronics with Vacuum Impregnation vs Potting

Posted by Andy Marin on Tue, Aug 31, 2021 @ 08:37 AM

The use of electronics in automobiles has made cars faster, safer, and more reliable. Electronics have become so prevalent that they're practically a commodity in the same way that aluminum and steel are. As this trend continues, manufacturers need solutions that address the leak paths that occur naturally in the manufacture of these components.

Preparing Parts for Vacuum Impregnation

Posted by Dan Irvin on Fri, May 28, 2021 @ 08:44 AM

Vacuum impregnation is the most effective way to seal porosity. But for it to be effective, one must adequately prepare parts prior to impregnation. Vacuum impregnation preparation involves having the parts clean and dry. If any residual fluids or debris are on the parts prior to impregnation, then the following problems may occur.

How to Seal Die Casting Porosity?

Posted by Andy Marin on Mon, Nov 02, 2020 @ 08:44 AM

Die casting is a metal casting process that injects molten metal through high pressure into a die. It is an economical process that can manufacture a high volume of parts. While die castings have a good surface finish and are dimensionally accurate, porosity inside the part is inevitable.

This blog will define die casting porosity, problems porosity causes, and how vacuum impregnation seals die casting porosity.

Correcting Three Vacuum Impregnation Myths

Posted by Andy Marin on Mon, Nov 25, 2019 @ 09:43 AM

In some die casting applications, components must also be pressure-tight to hold pressurized fluid or gases. Companies use vacuum impregnation to meet these requirements by sealing the internal leak paths caused by interconnected porosity.

 

Misconceptions and lack of information about the vacuum impregnation process can hinder its implementation, which may increase unforeseen costs and negatively impact part quality. This piece demystifies vacuum impregnation by correcting three common myths.

Can Vacuum Impregnation Seal Cracks?

Posted by Andy Marin on Wed, Oct 30, 2019 @ 09:00 AM

In some die casting applications, components must also be pressure-tight to hold pressurized fluid or gases. Companies use vacuum impregnation to meet these requirements by sealing the internal leak paths without impacting any other features of the casting. A commonly asked question is in addition to leak paths, can vacuum impregnation seal cracks?

Video: When Should I Impregnate a Casting

Posted by Andy Marin on Thu, Jun 20, 2019 @ 08:50 AM

The goal of a foundry is to produce high quality die castings that meet or exceed the customer’s specifications at a competitive cost.  In some die casting cases, those specifications require that the part must hold pressurized fluid or gasses. Companies use vacuum impregnation when the part must hold fluids or gasses under pressure. A common question asked about vacuum impregnation is “When Should I Impregnate a Casting?” This video addresses this question by answering if vacuum impregnation should be done before or after machining and finishing.
