FIELD: process engineering.SUBSTANCE: invention relates to forming of plastics. Proposed forming appliance comprises first and second structural parts and billet to be heat-formed arranged there between. Note here that first and/or second structural part is configured structurally and/or with allowance for material properties so that magnitude of its thermal expansion in different directions has different value. Note also that said first and/or second structural part with different expansion in different directions comprises a carbon fibre-based plastic ply and ply of plastic reinforced by glass fibres. Said carbon fibre-based plastic ply and ply of plastic reinforced by glass fibres are arranged unparalleled.EFFECT: higher quality of finished products.15 cl, 2 dwg |
