Considering the detail-oriented nature of this process, how likely is it that such a premium quality fabrication technique could be maintained if the Powder Metallurgy tools used here didn’t have equally outstanding build qualities? Like a supercomputer that was inputting rubbish and kicking out more rubbish, second-rate PM tools could only ever manufacture second-rate sintered […]

Vacuum sintering adds atmosphere-less processing to a powder metallurgy equipment line. Basically, there’s a pump to remove air from the sintering chamber. Outgassing binders are next. They’re removed from the compacted Green part before the powdered material is exposed to coalescing heat. Free of process chemicals and oxidizing gasses, the operation acquires a super-clean particle […]

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 sintered parts. Because the PM production process utilizes a density controllable metal forming technique, all sorts of applications become feasible when sintered components apply their […]

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 oil carrying lines, or they were periodically greased by busy maintenance technicians. Interestingly, focusing on that self-regulating lubricity feature, sintered bushings are loaded with different […]

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 compaction densified metal elements. That, then, is a big part of a bearing manufacturer’s motivation for adopting sintering technology. Of course, there’s also that self-lubricating […]

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, […]
