When manufacturing powdered metal parts, your supplier drops precise amounts of powder into a mold or cavity. The powder is then compacted with a punch, ensuring that every strand of the mold is filled. After release, the compressed part enters the furnace for sintering. This fuses the powder particles to form a hard-finished or semi-finished part.
There are two ways to process powder metallurgy parts. Using resin to infiltrate the pores improves lubrication and reduces chatter. In addition, some material additives, especially manganese sulfide, can reduce cutting force and wear.
Powder metallurgy has many advantages over machining. Because it is fast and efficient, lead times, energy consumption, and material waste are reduced.
At the same time, it opens up more material possibilities. However, as a result of pressing the powder, certain features cannot be formed. In this case, if you want these features, you have to do secondary machining operations.
