How Do Particle Size and Size Distribution Influence the Compaction Process in Powder Metallurgy?

May 16, 2019

Scientific precision shapes Powder metallurgy processing. While a post about compaction basics could get away with describing the process in a few simple lines of text, these rudimentary descriptions would fail to capture the complexities that arise as a powder pressing operation proceeds. Right now, with a precision-based approach foremost, we’re going to delve deep […]

Hot Pressing vs. Cold Pressing of Metal Powders: What’s the Difference?

May 2, 2019

Back at the compaction chamber, two alternative pressing systems are available. In the hot pressing method, elevated temperatures are used. It’s a dual-process operation, with the powdered metal compacting, then it sinters. Almost solid, just slightly porous, the combined processing approach yields tool quality results. Alternatively, cold pressing is done without heat. That latter phase […]

Understanding Atomization Method in Powder Metallurgy

April 16, 2019

This phase of the powder metallurgy process hasn’t received adequate attention. Here’s an opportunity to remedy that oversight. Actually, that’s not quite true, past articles have described the electric arc phase, but that’s hardly the only option. Grabbing this chance with both hands, let’s delve deeper into the powder dispersing options. What Is Powder Atomization? […]

Why Understanding Powder Behaviour in Metallurgy Matters

April 5, 2019

Exotic energies are at work when powdered metal particles are compressed. Further back, even stranger reactions take place in a mixing chamber, where fluid dynamic forces regulate the early stages of the powder metallurgy process. No worries, though, to a process engineer and his technician team, every physical and fluid-based law is intimately known and […]

The Role of Binders and Lubricants in Powder Metallurgy

March 19, 2019

Exotic recipes blend to create hardened products in the powder metallurgy sector. They’re packed with enigmatic chemical compounds. They flow in and around the metal particles so that the granules disseminate evenly and easily find their way into a die assembly. There’s no clumping, no material friction or substance stickiness to impede the process, not […]
