Abstract: This invention relates to a porous pulp mold comprising sintered particles and a plurality of drainage channels. The pulp mold of the invention can be produced in a fast and cost effective way. The molding surface of the invention comprises small pore openings, to evacuate fluid and prevent fibers from entering the pulp mold. Furthermore the pulp mold of the invention comprises drainage channels improving the drainage capabilities of the pulp mold. The molding surface can be heated to at least 200° C., due to high heat conductivity of the pulp mold and its ability to withstand high temperatures.

Abstract: This invention relates to a method for forming a three dimensional sintered body comprising the steps of a) providing a basic mould having a configuration adapted to the sintered body that is to be produced, b) treating the surface of the basic mould to facilitate application of a first surface layer of the sintered body, c) applying powder particles onto the basic mould, to form said first surface layer, d) applying at least one more layer on top of said first surface layer, e) heat treating the basic mould and the particles to form a sintered body, wherein step b) is performed by providing an adhering layer to the basic mould arranged to adhere the particles of at least a portion of the surface layer.

Abstract: The present invention relates to a method and a machine for making a fibre product. The invention also relates to a shaped body produced by the inventive method. According to the invention, a fibre product is formed on a first tool. The formed fibre product is then sandwiched between the first tool and a second tool and the surface of the second tool is heated to at least 220° C. to evaporate water from the fibre product. The tools are permeable to air and water When the fibre product has been dewatered to a dry solids content of at least 70%, the fibre product is subjected to microwave heating.
