CA 2588514

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