Increased Density in Powder Metallurgy Products: How can this be Achieved?
Powder Metallurgy produced parts continue to find their way into countless machine types. In fact, if a new machine comes to market, there’s a good chance it’ll use a few...
Common Applications of Sintered Bearings
Every industry insider knows about self-lubricating sintered bearings. They’ve pretty much transformed every machine architecture, large and small. Before these bushings came along, chunky multi-element bearings were fed by intricate...
Advantages of Sintering in Producing Complex Shaped Bearings
Without any difficult machining work, sintering services make it possible for engineering customers to acquire complex geometrical parts profiles. The detail-heavy components exit the powder metallurgy equipment as perfectly identical...
Role of Sintering Additives in Sintered Bearing Manufacturing
Remember, the sintering stage coalesces compacted metal objects. Pressed into shape by a die, heat is applied inside the sintering chamber. The metal doesn’t melt, but it merges and consolidates....
Dimensional and Geometrical Precision of Powder Metallurgy Products
Whilst cast parts can exhibit dimensional inconsistencies, powder metallurgy products are designed to repress such manufacturing glitches. A casting might expand because it’s still soaked in smelting heat, but PM...
The Essential Role that Powder Metallurgy Plays in Automotive Applications
The automotive industry utilizes scores of manufacturing technologies. Right now, the feature of the day is smart technology. Systems that help drivers stay safe are currently in the limelight. Lightweight...
What are the Factors that Determine the Compaction Pressure in a Sintering Process?
As a wad of powdered metal is pressed into its final form by a compaction mechanism, hydrostatic pressures trigger the start of the densification process. Particles of metal slide past...
How Does Powder Metallurgy Reduce the Need for Machining
For a plain-speaking answer to this question, standard Powder Metallurgy production sequences do indeed create dimensionally accurate items. An end-process part is so precisely manufactured, so close to being surface-finished,...
The Economic Advantages of Powder Metallurgy
Here’s a fact that’ll get the attention of manufacturers. Simply by adopting a Powder Metallurgy operation, great economic savings become feasible. Remember, there’s less machining to be done after a...
Factors that Affect the Sinterability of Metal Powders
No matter how well a line of sintering equipment is configured, how high-performing the equipment has proven to be in the past, particle coalescing challenges can occur. Perhaps randomly, without...
Powder Metallurgy: A Green and Sustainable Technology
Let’s flip the page on the P/M process. On that would-be cover page, powder metallurgy produces parts that are porous and self-lubricating. Turning the page in this make-believe informational brochure,...
The Role of Furnace Atmosphere in the Sintering Process
Above and around the powdered metal, the sintering atmosphere is also being regulated. Now, if someone were to ask, “What gas is used to control the different sintering vectors,” the...
How Do Particle Size and Size Distribution Influence the Compaction Process in Powder Metallurgy?
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...
Hot Pressing vs. Cold Pressing of Metal Powders: What’s the Difference?
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...
Understanding Atomization Method in Powder Metallurgy
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...
Why Understanding Powder Behaviour in Metallurgy Matters
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...
The Role of Binders and Lubricants in Powder Metallurgy
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...
Effects of a Miscalculated Sintering Temperature to a Sintered Material
During the sintering process, as applied to powdered metals, a densely packed, cavity-shaped cluster of machine-pulverized particles plasticizes and diffuses. They do not melt. That’s a common misconception. Now, assuming...
The Importance of Green Strength in Powder Metallurgy Process
As compacted metal powders coalesce, and this is before the sintering process, the compressed material is imbued with what’s known as “Green strength.” Remember, the metal particles haven’t bonded yet,...
What are the Major Stages of the Sintering Process?
The sintering process occurs after a mass of atomized powder has been compacted. Further back, the powder metal has been mixed and blended with a liquid phase. Oils and bonding...
Calculation of Sintering Temperature? How is it done?
Sintering technology is ruled by complex engineering equations. There are holding temperatures and material characteristics to regulate, plus a slew of phase transforming processes to regulate. Simply put, there are...
What Happens to Powdered Metal Parts During the Sintering Phase?
