A screwless faceplate assembly consisting of a single monolithic subplate component and a single monolithic faceplate component that is removeably attachable to the subplate component. The binder is applied to the semi-finished fiber material or the fiber preform and subsequently activated through increasing the temperature by conducting an electrical current through the carbon fibers of the preform. The colored grout is on the initial surface. The fill pipe includes seal flanges allowing its removal from the food material supply tubing and the fill tube to allow conventional cleaning of the remaining components of the apparatus. The invention further relates to an apparatus for carrying out the method. 1 to 50 parts by weight of a resin, wherein the resin is attached on the surface of the metal pigment, the process comprising applying an ultrasonic vibration during resin coating treatment.
