MOLD FOR MAKING NOZZLE ELEMENTS Russian patent published in 2024 - IPC B01J19/30 

FIELD: various technological processes.

SUBSTANCE: present invention relates to moulds used in production of packing elements for packing layers, in particular to a substrate for catalysts and to catalysts on a substrate. More specifically, the present invention relates to moulds used in the production of a ceramic substrate for catalysts, and to supported catalysts used in processes such as steam reforming and production of direct reduction iron. Mold for making a nozzle element from a liquid ceramic composition, wherein the mould includes a first portion and a second portion, wherein the first portion and/or the second portion are elastically deformable, wherein the first part and/or the second part include a plurality of open cavities of the mould, wherein first and second parts are made with possibility of bringing into contact with formation of closed cavities of mould, wherein the mould is configured to be moved from the open position, in which the first and second parts are partially spaced from each other as a result of the deformation of the mould part and in which the mould cavities are open, by reducing the deformation of part of the mould into a partially closed position, in which some cavities of the mould are closed, and then by further reducing the deformation of the mould part to the closed position, in which the first and second parts are brought into contact such that the mould cavities are closed.

EFFECT: group of inventions provides higher quality of manufactured articles.
