FIELD: metallurgy.
SUBSTANCE: invention relates to a pair of metal half-moulds for moulding cellulose pulp by compression and heating. Technical result is achieved by a pair of metal half-moulds, suitable for cellulose mass moulding by compression and heating, which contain the first semi-mould for application of suspension from cellulose mass and the second half-mould corresponding to the shape of the first half-mould. At that metal surface of the first half-mould is covered with elastomer material by means of spraying or casting.
EFFECT: technical result is high strength and quality of surface of large articles from cellulose mass.
