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.

Should Vacuum Impregnation Be Done Before or After Finishing?

Posted by Andy Marin on Thu, May 02, 2019 @ 03:44 PM

Powder coat, paint, chromate conversion, or anodizing, are common finishes applied to die cast parts to improve their performance or appearance.  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.

Case Study: How Portable Equipment Solved Production Capacity Issues

Posted by Andy Marin on Wed, Apr 03, 2019 @ 01:36 PM

The casting industry is in a transitional period adjusting to new trends and products. Manufacturers require flexibility in their equipment to account for shorter program life cycles while still being able to be competitive. In many instances this requires assets to be spread across multiple programs. It is a landscape that rewards companies who identify opportunities to adapt to the changing circumstances. One example is a case where vacuum impregnation requirements unexpectedly and suddenly increased in one manufacturer's location while another of its locations had underutilized impregnation capacity.

Useful Lessons from Henry Ford about Vacuum Impregnation

Posted by Andy Marin on Fri, Jan 04, 2019 @ 02:50 PM

As manufacturing equipment ages, the maintenance and repair (MRO) of the equipment increases while the Overall Equipment Effectiveness (OEE) decreases. Given this, companies must decide while bidding on new projects:  “Use the aged equipment and invest in MRO while accepting a lower OEE” or “Invest in new equipment using the latest technology and generate a higher OEE.”
