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. By injecting special additives into this mix, we enhance this material coalescence phase. An increase in thermal energy temperature can’t duplicate this effect. As a […]

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 produced components don’t require anywhere close to that amount of metal-transformative energy. Because of that hallmark feature, powdered metals retain their Green compacted form. Even […]

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 materials, including stronger aluminium alloy and carbon fibre, are also creating a buzz. Given the quick adoption rate of these advanced vehicle materials, powder metallurgy-based […]

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 one another, they lock tightly together, and then a series of intricately embedded capillary systems take shape. On one side of a datasheet, pressure parameters […]

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, that it simply doesn’t require much additional machining. Of course, a straight-to-the-point answer might create more questions than it resolves. Ever mindful of this prospect, […]

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 PM produced component has been manufactured, so the finance department can zero out machine shop costs. It’s the same with finishing, with this phase of […]

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 any obvious source of concern, the Green Compact doesn’t fully fuse into one single workpiece. To fix this process-impeding state of affairs, a veteran trouble-shooter […]

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 technology shows off a whole other benefit. It’s right there, in quasi-real black and white, that this powder pressing and heating method demonstrates a […]

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 answer wouldn’t be short. You see, the equipment used to sinter metals is composed of several discrete stages. So, for every equipment zone, there’s a […]

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 […]
