Research Regarding the Increase of Durability of Flexible Die Made from 50CrMo4 Used in the Typographic Industry

A large amount of packaging used mainly in the food industry is obtained by technologies that involve use machines such as those cut with flexible die. The durability die a very important aspect and this regard purpose research was to identify for its development. Thus, considered analysis knives made 50CrMo4 steel considering hard chrome-plating treatment, well laser hardening knives. For tools, two technological parameters were considered, namely moment tightening force, which had values range 50 Nm–110 Nm, cutting speed, adjusted 50–60 m/min. die, wear tools taken into account, maximum length material.
