Technology of making hollow parts with iron core

摘要

Technology of making hollow parts with iron coreThe invention relates to a method for manufacturing a part, which at least comprises the following steps: obtaining (110),A core having a porous internal structure and an uneven porosity is manufactured by an additive to form (120) an assembly comprising an element having the shape of the part to be manufactured in which the core exists, A member (130) formed by introducing a material into an element around the core, and a core (140) selectively removed by introducing a liquid medium suitable for dissolving the core material into a porous structure of the core.Abstract figure: Figure 1.
