Abstract RU 2593568 C2

FIELD: pulp and paper industry.

SUBSTANCE: invention relates to tooling for moulding articles from cellulose. Device for moulding comprises a mould and a support plate with a cavity and flat support surfaces. Mould has porous body made by sintering and having outer moulding surface and inner surface. Mould inner surface is machined after sintering powder zone. Said mould surface zone is intended for connection with support surfaces of support plate to make vacuum chamber.

EFFECT: producing a high-quality mould, which does not require a large amount of energy for heating of shaping surface, a method which does not require high time expenses.
