METHOD FOR TRANSFER MOULDING OF PROFILE-TYPE PARTS Russian patent published in 2021 - IPC B29C70/48 

FIELD: moulding.

SUBSTANCE: invention relates to a method for transfer moulding of profile-type parts. The technical result is achieved by a method for transfer moulding of profile-type parts, including manufacturing a preform from a reinforcing material, followed by impregnating and creating a vacuum. The profile-type preform therein is created by radial weaving over an elastic punch with a rigid mandrel, followed by placing the preform with a removed rigid mandrel in the matrix of the enclosing tooling, pressing by a punch and sealing the ends. An overpressure is then created in the elastic punch, followed by impregnating the preform while creating a non-pressure therein. The operations with supply of overpressure and creation of a vacuum in the elastic punch are therein repeated until the required filling coefficient of the manufactured profile-type part is reached.

EFFECT: expanded range of manufacturing profile-type parts, improved quality and increased filling ratio.
