Abstract

Oppfinnelsen er en metode for fremstill- ing av keramisk form eks. for forming eller støping av komposittmaterialer, glass eller metaller, og inkluderer følg- ende steg: tvangsblanding av keramisk basert pulver (1) i tørr form i en tvangsblander (5), for jevn fordeling av bestanddelene i det tørre keramiske pulveret, og som er basis for formmassen (14); karakterisert ved sakte og jevn tilsetning av en vann- blanding (2) innholdende en liten mengde middel for å hindre overflatespenninger (4) i pulveret (1) i tvangsblanderen (5), resulterende i en formmasse (14); sakte og jevn tilsetning av for- sterkende fibere (3) i formmassen (14) i en arbeidende tvangsmikser (5); overføre formmassen (14) til et vakuumkammer (7); pumpe ut luften fra vakuumkammeret (7) og overføre vakuumkammeret til et roterende underlag (7b) for rotering og evakuering av innesluttede luftporer fra formmassen (14); og injisere/overføre formmassen (14) inn i formen (11), og la denne størkne/herde i formen.The invention is a method for making ceramic molds, for example. for forming or casting composite materials, glass or metals, and includes the following steps: forcing mixture of ceramic based powder (1) into dry form into a forcing mixer (5), for even distribution of the constituents of the dry ceramic powder, and being base of the molding mass (14); characterized by the slow and steady addition of a water mixture (2) containing a small amount of agent to prevent surface tension (4) in the powder (1) in the forced mixer (5), resulting in a molding compound (14); slowly and uniformly adding reinforcing fibers (3) to the molding material (14) in a working composite mixer (5); transferring the molding mass (14) to a vacuum chamber (7); pumping out the air from the vacuum chamber (7) and transferring the vacuum chamber to a rotating support (7b) for rotating and evacuating entrapped air pores from the molding mass (14); and injecting / transferring the molding mass (14) into the molding (11) and allowing it to solidify / harden in the mold.
