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.

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.

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.

How to Eliminate Sealant Contamination

Posted by Andy Marin on Wed, Oct 21, 2020 @ 08:51 AM

A common frustration we hear from manufacturers is that their vacuum impregnation process may seal porosity, but some parts still need to be scrapped due to sealant contamination (Image 1). Most of these manufacturers assume this is normal. The fact is that this is not normal, nor should it be accepted as a typical outcome of the vacuum impregnation process.
