PM Technology vs. Traditional Forging ApplicationsAugust 6, 2021
When it comes to the creation of metal parts, industries have the option to opt for many processes. Some may want to go for the traditional processes, while others may want to embrace the modern ones.
One traditional process that industries seem to rely on is forging. Forging is a type of manufacturing process that maximises localised compressive forces from a hammer or a die in shaping and forming the metal parts. This specific process has been utilised for a very long time given that it can easily generate all the parts needed by businesses. However, its limitations paved the way to the rise of other processes.
The Evolution of the Forging Process
As previously stated, forging is generally done by maximising a hammer or a die in shaping and forming metal parts. But with the continuous evolution of technology, the traditional forging process has likewise progressed and sprouted into different useful variations.
Some of the variations of forging are open die forging, closed die forging, precision die forging, and powder forging. Open die forging entails the shaping of heated metal parts that are located between a ram and a hammer, anvil, or bolster, all without any die structure. Closed die forging, alternatively, involves transferring white hot steel into a series of shaped dies before forming it through multiple press strikes. Precision die forging is somehow similar to closed die forging and aims to construct a near-net or final shape. Powder forging, ultimately, generates a near-net shaped powder metal part without flash.
Most forging processes have generated parts with good mechanical properties, fatigue and impact resistance, and ductility. They are even maximised by industries as the processes can work with almost all types of ferrous and non-ferrous metals. But even though these forging processes are deemed to be useful, industries still want to find some alternative.
PM Technology as a Reliable Option
One alternative to the forging process is powder metallurgy (PM). Basically, it is a process that involves the heating of compacted metal powders right below their melting points.
The PM technology is being utilised as an alternative or even a replacement in some cases to the forging due to its benefits. First, the process involved in PM technology can maintain closer dimensional control. Additionally, it can sustain better tool life. These features are possible due to the advancements and developments in compaction, alloy design, and ultra-high temperature sintering.
Parts and products made from PM technology can gain notable strength and outstanding complexity in terms of their shape, especially if ultra-high temperature sintering and unique alloy designs are combined. The processes involved in the said technology are likewise known for reducing tooling and parts costs as well as minimising scrap waste.
Forging may have some advantages over PM technology, but the latter is preferable if you will be producing parts with complex dimensions and geometries. PM technology is likewise better for your application if you do not want to conduct secondary operations.
