The uppers, especially if leather made, require heat treatments that allow to iron and stabilize it on the last. Mainly there are two types of treatments, one hot and one cold, which are made by machines with different types of technology. After lasting the upper on the last, you need to make a heating cycle, which allows the leather to stretch and overlap better to the last, avoiding the presence of wrinkles. At the end of the shoe assembly, after the press, it is necessary to perform a cold treatment with the appropriate chiller, in such a way as to allow the stabilization of the upper and the crystallization of the glue.
Below there is a summary table about the characteristics of all our heat treatment machines.
