  • This tooling material has been produced since 1995 by Portec Ltd. in Switzerland. Portec sells the porous tooling composite in machinable blocks called Metapor and in a castable form dubbed Espor.

    The tool is made from 65-90% aluminum powder and 10-35% epoxy resin epoxy resin binder. A proprietary process creates a block of metal that contains 15% empty space in the form of tiny interconnecting channels. On the surface, those channels terminate in pores of 15-16 microns diameter.

  • Can you please explaine what is a 100% porous mold... I mean what the material is that you are using. With no drilling, I'm stumped how you are doing this.
