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.
