| description | The manufacturing of an elastomer based polymer composite or textile/metal reinforcement composite partly on revolution surface, comprises overmolding of the insert with the polymer composition by an injection of the composition in an injection mold (40). Each composite comprises multiple crests, which are separated from each other in two troughs to form peripheral undulations making radial projection towards an external side of the composite, a bend with cylindrical or truncated end, and a strengthening insert with mesh. The manufacturing of an elastomer based polymer composite or textile/metal reinforcement composite partly on revolution surface, comprises overmolding of the insert with the polymer composition by an injection of the composition in an injection mold (40). Each composite comprises multiple crests, which are separated from each other in two troughs to form peripheral undulations making radial projection towards an external side of the composite, a bend with cylindrical or truncated end, and a strengthening insert with mesh. The mesh is made up of knit fabric, tissue or plait and covered by a polymer composition on one side of the insert. The injection mold contains each preformed insert partially on the revolution surface. The injection mould such as a vertical mold is used so that the injected polymer composition flows axially on an internal radial side of the preformed insert. The preformed insert is blocked using a pressure on a first peripheral edge of the insert, is axially blocked by nipping of a rolling portion of the first peripheral edge following a closure of a lid (47) of the mold, which is fixed on an end of a core and against the shells, and is radially blocked by the nipping of the first peripheral edge of the mold with a clamping of two external split rings against the lid cap of the mold. The preformed insert is obtained by a radial compression of the insert, which is pre-positioned on the core of the mold through a shell-closing of the mold against the core for flattening the insert in preformed state on the core. The polymer composition is injected at a pressure through the preformed insert mesh so that each composite has the polymer composition on each of two internal and external faces of the mesh. The first edge of the insert is nipped between the split rings and the cap. The polymeric composition is injected through an injection nozzle of which an outlet communicates with an interstitial space between the lid and the e |

The injected polymer composition flows from the center of end of the core towards the first peripheral edge of the insert, then axially up to a second peripheral edge of the insert. The end of the core has a surface to allow the flow of the polymer composition towards the first peripheral edge. The insert is made up of knitting textiles such as a knitted mesh (Jersey), and comprises aramid and/or polyester based thread. The elastomer based polymer composition is apt to resist oil and compressed air.
