Thermocompression SMC/BMC :
This process for moulding short-fibre compounds with a thermosetting or thermoplastic matrix is perfectly suited to the production of parts with complex geometries. The size of the fibres and their random orientation limit applications with high structural stress. Nevertheless, it is ideally suited to many applications, particularly as an alternative to metal.
Thermocompression of thermoplastic and thermoset composites:
This process is perfectly suited to the mass production of structural parts of intermediate geometric complexity. The geometric complexity will be limited by the deformation capacity of the prepreg.
Thermo-stamping :
Thermo-stamping of thermoplastic matrix composites is a high-speed alternative to thermo-compression. It is ideally suited to the manufacture of parts of intermediate geometric complexity at high production rates that can be automated.

Crosscomp® technology: high-performance TP overmoulding of composite structures
Geometric complexity is a major issue in the manufacture of long fibre structural parts. Our Crosscomp® technology solution enables us to manufacture structural parts with complex geometries using short cycle times and automated processes.
Structural strength is provided by a composite core with a simple geometry (flat, tube, etc.) obtained by pultrusion or thermoestamping. Geometric complexity and functional integration (e.g. metal inserts) is achieved by over-injection of thermoplastic onto the structural core. The result: parts that could not be made using conventional processes, produced at high productivity levels.
Crosscomp® technology is an ideal alternative for improving productivity and reliability in the manufacture of composite parts.

SMC comes as pre-impregnated sheets, ideal for manufacturing large flat or structural parts. BMC, on the other hand, is a paste-like compound used in compression moulding, and is perfectly suited to small parts with complex geometries. The choice between the two materials mainly depends on the part’s geometry and the mechanical stresses involved.
Yes, composite moulding works just as well for prototypes as for medium production runs. When investing in dedicated tooling isn’t justified yet, we guide your project towards the most relevant solution. Beyond that stage, we industrialise production while keeping tight control over the quality of each part.
Yes, compression moulding is particularly well suited to structural parts. The material is compressed in a heated mould, ensuring good mechanical strength and an even distribution of fibres. This process meets the needs of components subject to high stress, where light weight and strength both matter.
Yes, composite moulding often replaces a metal part when weight reduction becomes a priority. For comparable strength, a composite part weighs less than its metal equivalent, which benefits onboard assemblies. The actual gain depends on the material chosen and the stresses the part has to withstand.
An improved composite part is designed around all of its constraints, not just its shape. Stéphanie Sorhouet, co-managing director, puts it this way: “it’s a part that factors in all the functional and manufacturing constraints from the outset, which delivers greater reliability over the part’s life cycle.”
