ABSTRACT:
A casting mold for manufacturing grid plates for lead batteries makes use of easily interchangeable mold inserts for each half of a two-part, external metallic mold holder. The mold inserts are made of a highly porous microfiber nonwoven material, and render unnecessary the conventional cork-flour coating of casting molds due to good thermal insulating properties, high permeability to air and non-wettability by lead. The casting mold inserts are manufactured in a process which involves fixing of the nonwoven material with a curable binder either during or after shaping of the negative for the grid plate, so that the resulting parts assume a cardboard-like consistency.
