Cost Evaluation of Powder Metallurgy

As we all know, in powder metallurgy processing, before production, powder metallurgy manufactures will finish the evaluation of cost in material and cost in all kinds of processes, then figure out the total cost of a powder metallurgy project.

First, it’s about purchasing metal powders, which is very important. Normally, the usage of material available for powder metallurgy is 95% - 98%, and cost in total＝cost in material per gram*volumes*density.

After that, it’s about compressing powders into products, and cost in compressing is closely related to the tonnage of pressing machines, which consists of cost in machines and cost in workforce. The determination of tonnage of pressing machines is based on the product of the maximum cross-sectional area Perpendicular to the direction and the unit pressing pressure. Different parts require different pressing pressure. High pressure achieves high density. Powder metallurgy doesn’t need many types of equipment, so that could achieve a high production speed.

And then it’s about mould cost. The mould used in powder metallurgy and metal injection molding is made of material with high strength and high hardness, which will keep the tolerance controlled closely. At last, it’s about fine finishing, polishing, and other treatments. Powder metallurgy consists of 4 basic steps. On the occasion of no reduction in quality, reduce cost in process has become a big problem in powder metallurgy.
