ORATECH puts its expertise at your service in order to accompany you in the development of the composite molding of your parts and in the realization of prototype parts and small series, from the technical-economic study to the transfer of technologies within your structure. Thanks to its experience, ORATECH is ready to realize your parts in composite moulding of big dimensions. We have the means for the realization of prototypes in composite materials (injection means, ovens, autoclaves, press, etc.). ORATECH proposes in collaboration with GEBE2 the automation of the means of injections and press. Our skills in manufacturing composite prototypes and small series Technical and economical study Selection of materials and processes Calculations and simulation Design of the tooling Realization of the tooling Implementation (feasibility, prototyping, pre-production) Controls (3D, NDT) Machining Assembly Testing Industrialization Technology transfer Our methods and processes for the manufacture and shaping of composite mouldings : Consolidation: Curing of thermoplastic composites (= polymerization for thermosets) Draping : Laying of fibers (dry or pre-impregnated with resin) in the form of fabric. Superimposition of fabrics in different orientations Stamping : Implementation of a part from a flat plate. Shaping of the plate in a press with “punch/die” tooling Hot Forming/Bending/Preforming : Forming of dry or pre-preg fabrics on a heated tooling (punch/die) Infusion/LRI: Liquid Resin Infusion: Vacuum suction of resin to impregnate a stack of dry fabrics, all in a vacuum environment
