Abstract: The process for making a press plate having a flat press surface includes applying a liquid synthetic epoxy resin plastic material to a support surface of the press plate; allowing the liquid synthetic epoxy resin plastic material to run freely under action of gravity until it is uniformly distributed on the support surface and a layer with a flat and horizontal surface is formed on the liquid synthetic epoxy resin plastic material; providing projecting support walls along edges of the support plate for retaining and preventing loss of the liquid synthetic epoxy resin plastic material; and allowing the liquid synthetic epoxy resin plastic material to harden without vibration for up to seven days. The liquid synthetic epoxy resin plastic material is hardenable so that the press surface formed on the layer has sufficient hardness and the liquid synthetic epoxy resin plastic material is sufficiently elastic to compensate for expansion of the support plate, while retaining a flat smooth press surface.
