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.
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.
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.
To meet global customers' needs, automotive Original Equipment Manufacturers (OEMs) must develop international supply chains. And when an OEM seeks to create a sustainable and efficient supply chain in a new country — regardless of whether that country has an existing manufacturing base — it is inevitably going to face challenges.
On average, a new automobile has approximately 40 electronic controllers, five miles of wiring, and more than 10 million lines of software code. Electronics, coils, and wires used in automobiles will expand to meet fuel efficiency and consumer standards.
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.
