It happens quite often that insufficient attention is paid to the study, construction and maintenance of basic tooling, that once manufactured is used for a long time, often for decades. Compes is aware of the problems that the extruder can meet in the production cycle each day and over the years. Dead time, difficulty in assembly and handling are unnecessary economic losses. For this reason Compes has established a technical office and a specific department for the construction and maintenance of dieholders, bolsters, reaction plates and so on.
