Abstract
The present invention relates to at least one mold (2) produced by additive manufacturing method; at least one layer (3) (laminated) of resin-impregnated fabrics laid on an outer wall surface of the mold (2); at least one vacuum bag (4) which is placed to substantially cover the layer (3) and allows vacuuming; at least one furnace (5) which enables the layer (3) to be cured by heating, applies pressure to the layer (3) at a pressure value predetermined by the user, and into which the mold (2) is placed; at least one part (6) formed by curing the layers (3).
Claims13
A production system comprising at least one mold produced by additive manufacturing method;
- at least one layer (laminate) of resin-impregnated fabrics laid on an outer wall surface of the mold;
- at least one vacuum bag which is placed to substantially cover the layer and allows vacuuming;
- at least one furnace which enables the layer to be cured by heating, applies pressure to the layer at a pressure value predetermined by the user, and into which the mold is placed;
- at least one part formed by curing the layers, wherein at least one additional vacuum bag enabling an inner wall surface of the mold to be vacuumed, and allowing the mold to be vacuumed without breaking such that the mold withstands the pressure inside the furnace during a curing process, thereby keeping the mold rigid;
- the mold which has a brittle structure so as to be removed from the cured part, and is removed from the part by the manufacturer by breaking.
A production system wherein the part which is produced by:
- producing the mold by additive manufacturing method;
- obtaining the layer (laminated) forming the outer wall surface of the mold by laying the fabrics on the mold;
- placing the vacuum bag on the layer, wherein the vacuum bag allows vacuuming by substantially covering the layer;
- vacuuming the inner wall surface of the mold by the additional vacuum bag;
- placing the mold and layer in the furnace, which has a temperature and/or pressure value predetermined by the user;
- applying pressure on the wall of the mold during curing by means of the additional vacuum bag, so that the mold is kept rigid without breaking;
- breaking the mold to remove the part from the mold.
