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.

Strategies for Acquiring and Financing Vacuum Impregnation Equipment

Posted by Andy Marin on Thu, Jun 03, 2021 @ 08:55 AM

The benefits in owning and operating equipment vs. outsourcing are found in the savings of logistics, quality, and part costs. These savings serve to increase a company’s profitability. This reality holds true for vacuum impregnation equipment. But with many projects and programs competing for a limited amount of capital expenditure dollars, owning vacuum impregnation equipment can seem out of reach. Therefore, many companies default to outsourcing their vacuum impregnation requirements.

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 Vacuum Impregnation Improves Powder Metal Machining

Posted by Brett Eyring on Mon, Apr 26, 2021 @ 11:34 AM

A major benefit to manufacturing with powder metal is that parts are made to near net shape. Often, machining is thus only a secondary operation for improving shape precision and surface quality.

Five Reasons Why Companies Bring Vacuum Impregnation Equipment In-house

Posted by Andy Marin on Wed, Jan 06, 2021 @ 01:21 PM

The beginning of the 21st Century was a turning point for vacuum impregnation equipment. In two decades, considerable improvements have been made in impregnation technology that has been unchanged since the 1950s. Since the early 2000s, many companies have brought redesigned and modern equipment in-house.


The five main reasons why companies bring vacuum impregnation in-house are:

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.
