FIELD: metallurgy.
SUBSTANCE: composite material consists of material of basis and thermoplast deformed layer with convex and recessed sections. Herewith thermoplastically deformed layer in the range of convex sections are implemented thinner than in the range of convex sections. Additionally thermoplastically deformed layer is applied by matting or extrusion on basis material and then at simultaneous forming is heated up to softening temperature. Group of inventions also relate to application of composite material, manufacturing by mentioned above method for glyptic of sealing elements in the form of cup cover.
EFFECT: there is provided manufacturing of sealing elements, storing by piles which are by simple method transferred for its following usage and which, herewith, simultaneously allows acceptable for consumer appearance.
