Direct manufacturing of non-stick molds via single point incremental forming

摘要

In the present work, a technique for forming non-stick molds from pre-coated sheets via single-point incremental deformation is explained. Four truncated pyramidal geometry specimens have been formed and the characteristics of the coating after deformation (thickness, roughness, adhesion to the substrate and pencil hardness) have been measured. Coating characteristics in deformed areas are slightly lower than those measured in non-deformed areas. In any case, the values obtained are compatible with the standards used in the sector dedicated to the manufacture of molds for alimentary use.
