Two methods are developed for production of folded structures: synchronous and cyclic.
The point in synchronous method is simultaneous deforming of the sheet along the lines of the template. Deformation is performed using transformable mandrels and conjugate or non-conjugate schemes.
- Short time of sheet deformation into a finished folded structure
- Doesn’t depend on the material: folded core may be produced from different materials without additional adjustment of production unit
- Diversity of reliefs and dimensions of the cores being manufactured
- Difficult to apply this method to continuous roll materials
- Difficult to make the process automatic and continuous

The point of cyclic method is gradual deformation of prepared sheet. Deformation is performed by step-by-step transformation of preliminary folded linear crimp into folded core. Deformation is performed either by transversal crimping or into transformable stamps.
- Possibility to produce folded core from continuous roll material
- A possibility to make the process automatic and highly efficient
- Sensibility to the material: it is necessary to select individual parameters of the process for each material
- Attachment of the process to a given relief – it is possible to change only separate parameters of core relief
