  • the press plate is made of metal, preferably of light metal, such as aluminum. The sprinkled with the mixture press plate is then retracted in a heated press. There, the mixture is pressed and formed the plate-shaped component.
  • the pressure plate is designed so that water or liquid contained in the mixture, resulting from the reaction of the mixture components contained during pressing, can escape without damaging the plate body, for example by bubbling.
  • the press plate may have pores or be provided with a microperforation.
  • the press plates may consist of sintered materials, in particular sintered metal, which have a porosity and absorb or dissipate moisture.
  • a metallic press plate has the advantage that heating of the plate-shaped component during pressing takes place from below. This results in a more uniform curing of the plate-shaped component.
