Patent
CA 2473406
The invention provides a mold for use in a compression molding apparatus that has a frame part (41) with a hole through its center; a bottom plunger (42); and a top plunger (43); wherein the plungers are fabricated to fit substantially snugly in the hole in the frame part, and wherein at least one plunger comprises at least one low-thermal conductivity insert (44, 44~). The mold is useful in compression molding processes used in the preparation of unitized membrane electrodes.
La présente invention concerne un moule destiné à être utilisé dans un appareil de moulage par compression qui comporte une partie carcasse au milieu de laquelle se situe un trou; un piston inférieur; et un piston supérieur, lesdits pistons étant fabriqués pour épouser sensiblement la forme du trou de la partie carcasse, au moins un des pistons comportant au moins un élément rapporté à faible conductivité thermique. Ce moule est utile dans des processus de moulage par compression utilisés dans la préparation d'électrodes-membrane unifiées.
