TEMPORARY RETENTION OF METAL SHEET ON MOULD USING MICROWELD JOINTS Russian patent published in 2016 - IPC B29C65/44 B29C65/70 B29C45/14 

Abstract RU 2585025 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of injection moulding resin, such as injection moulding of polymers and connection with other materials. Method enables to make a component part comprising a body made from polymer material and sheet or strip of metal forming surface of component part. Component part may represent annular casing of an axial turbomachine compressor with composite annular metal wall. Method includes following steps: (a) placing (104) and retention of metal sheet on mould surface by means of fasteners, such as welding seams or microweld seams, or other connectors; (b) injection and curing (110) of resin in mould to make body by binding with leaf; (c) release of (111) of metal sheet of fasteners, when component part is exposed to splitting force (62), and component part is released.

EFFECT: technical result achieved using method according to invention consists in providing accurate positioning and fixation of metal sheet at its deformation and injecting resin into mould to prevent its displacement.
