Powder metallurgy

Sintered molds

Many mechanical items in the most varied sectors are produced using sintering technology, so let's talk about powder metallurgy.

Metallic powders, carbides and ceramics are the most common examples of materials that are treated with this technology in order to obtain components with high toughness and wear resistance or that require a controlled porosity inside them.

The procedure involves pressing the powder inside the molds, this gives rise to a semi-finished product characterized by a very fragile consistency which, if necessary, can be worked with machine tools; finally, sintering modifies the material structurally giving it the desired hardness and density.

In the case of parts where tight tolerances are required, and where the type of material allows it, the sintered pieces can be calibrated through a subsequent molding phase.
