FIELD: performing operations.
SUBSTANCE: invention relates to a method of producing articles by vacuum infusion. Proposed method comprises laying preform on tooling, forming inner and outer packs sealing the preform, including laying of binder feed line and vacuum line in inner pack and laying of vacuum line in outer pack. Then, the inner pack is evacuated by connecting the vacuum pump line to the binder feed line while controlling the vacuum level in the vacuum line of the inner pack. Outer pack is evacuated by connection of pack vacuum line to vacuum pump line at control of vacuum level in pack vacuum line at the point remote from vacuum pump line connection point. After the packs are evacuated, the vacuum pump is switched from the binder supply line to the vacuum line and the binder supply line is connected to the binder source. Further, preform is impregnated with binder.
EFFECT: correct evaluation of vacuum in packs and obtaining of its proper level for creation of high-quality products with maximum full use of capabilities of lines available in packages.
