SALA PUNZONI's flat dies in high speed steel with nitriding surface coating can be reground several times because they are core-hardened. As a result, they have the same hardness and structural features both on their surface and along their whole section. Therefore the performance of a reground Sala Punzoni’s flat dies set reaches about the 80% of the performance of a new flat dies’ set.
The usage of high speed steels allows us to coat the flat dies a lot of times without any modification in the structure of their material.
Flat dies’ re-grinding service follows strict procedures: there is no difference during the working process between new and re-ground flat dies.
SALA PUNZONI offers also a fast pick up and delivery service both for Italian and foreign customers.
