A thermoforming process at low temperatures (about 50°) using a technology traditionally used for wood and carbon processing.
The leather is sprayed with a chemical agent on the flesh side that acts on the fibers and makes the thermoforming permanent. The chemical agent does not transmigrate to the grain side, does not interfere with the glues, and allows the leather to be processed under a membrane molding machine, giving it the three-dimensionality of the mold on which it rests thanks to the action of the vacuum.
Low temperatures avoid the damage to the leather that there can be in the case of techniques such as high frequency or hot molding that work at temperatures twice as high.
