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:
In its latest report, IHS Markit's Purchasing Managers Index (PMI) offers a picture of the U.S. economy's current state. Led by manufacturing, U.S. business activity expanded at the fastest rate in more than five years.
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.
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.
This year's NADCA Diecasting Congress and Table Top Conference has transitioned to virtual. Watching a screen will require a different kind of focus instead of attending the technical sessions or walking the exhibitor floor. Before attending, here five tips to help you make the most of your time.
There exists a misconception on testing requirements for vacuum impregnation sealants and vacuum impregnation processes. Testing impregnation sealants for application compatibility and testing the impregnation process effectiveness are grossly different.
In 2008, a North American motorcycle OEM decided to insource their vacuum impregnation requirements to reduce manufacturing costs. The OEM considered multiple sealant and equipment technologies. The company was sold on equipment that claimed to eliminate wastewater discharge, seal castings at a better rate, and would require minimal adjustments, maintenance, and repair. The equipment selected used a recycling sealant.
The Continuous Advanced Powertrain Impregnation system (CAPI) allows high volume OEM and suppliers to have the benefits of vacuum impregnation in a simple, easy to use machine. In our latest video, Johnny Impreg discusses how the system effectively seals die casting leak paths while eliminating contamination and damage.
Automotive manufacturers realize that being environmentally responsible and profitable are not mutually exclusive. Being environmentally responsible can achieve better growth, cost savings, improve brand recognition, and increase profitability. The environmental impact of the responsible use of resources is beneficial to everyone, and automotive manufacturers play a leading role.
Back by popular demand, John Halladay (aka Johnny Impreg) shows our latest vacuum impregnation system, the Advanced Powertrain Impregnation system (APi). The APi allows powertrain manufacturers to have the benefits of vacuum impregnation in a simple, easy to use machine.
