What is powder metallurgy high-speed compaction method?

Powder metallurgy (PM) is a modern metal part forming technology with metal powder as the main raw material. The parts formed by powder metallurgy process are very close to the finished parts and do not require secondary processing. But in powder metallurgy production process, which operation is the most difficult? We have to say that every processing operation is very important, from powder mixing to compaction, sintering and secondary processing. So what is the powder metallurgy high-speed compaction method?

Sweden has proposed a more advanced compaction method, namely high-speed compaction, which is a major breakthrough in the powder metallurgy industry. As with the traditional compaction method, the hydraulic compactor used by the manufacturer has a compaction speed of 500-1000 times of the traditional compaction speed, and the head speed is 2-30m/s, which is very suitable for large-scale production.

The hydraulically driven hammer (5-1200 kg) will produce a continuous strong shock wave, which can be transmitted to the metal powder in the mold cavity through the compaction mold to make the metal powder become dense. Therefore, through high-speed compaction, manufacturers can use small tonnage compactors to manufacture oversized parts (>5 kg), thus reducing production costs.

Especially in the field of automobile parts manufacturing, such as car seat parts, wheel hub, flange, gear, bearing, rod and gasket, high-speed compression molding is becoming more and more popular.
