Sintering is a thermal process largely exclusive to powder metallurgy (PM). The powder metallurgy sintering process frees engineers from many limitations inherent to traditional design in both structural and magnetic applications:
Today, advanced powder metallurgy processes can provide strength and design flexibility superior to casting. And PM requires less secondary machining, allowing for more material flexibility than forging.
If you still don’t have a good handle of whether sintering can expand your design options and improve material properties, ask our world-class team directly. You can also keep learning on your own by scrolling to the resources below.
Our team includes Senior Advanced Materials Engineer Fran Hanejko and Director of Technology & Business Development Tom Freemer. Fran is a highly respected industry expert who’s published several research papers on sintering and powder metallurgy. Tom has collaborated with design engineers across several industries to create innovative PM solutions through advanced manufacturing techniques and material alloys.
Fran and Tom have extensive experience in powder metallurgy, including several years with a world-leading raw material supplier. If you have design or performance questions for them, get in touch here.
The evolution of powder metal (PM) bearings, and ultimately modern powder metallurgy, dates back to the late 1920s when the Chrysler Corporation needed a higher strength bearing for the clutch of their new inline 6-cylinder engines. During this time, they developed a sintered copper, tin, and graphite bearing with 25% porosity which was then filled with oil via vacuum impregnation. This provided greater load carrying capabilities than existing materials. Chrysler was awarded a patent on the material and processing and the modern PM industry was born.
Sintering is a powder metallurgy processing step with plenty of untapped potential.
We’ve previously discussed how high-temperature sintering can take your DC electromagnetic component’s properties to a level conventional sintering can’t match. Through recent advances in powder metallurgy -- like ultra-high-temperature sintering (UHTS) -- an even greater leap forward is possible:
All manufacturing processes and technologies have their share of pros and cons. Yet, when it comes to powder metallurgy, few processes have changed for the better in a relatively short period of time.
Today, the advantages of powder metallurgy rival many conventional manufacturing technologies -- even machining -- when it comes to the production of high quantities.
