58 Extrusion International 5/2018 FILM EXTRUSION Die Heads will be fit again Die heads form the heart of an ex- trusion line: their condition has a decisive influence on quality and productivity. Even the smallest impurities and irregularities can have a considerable influence on the quality of production. Regular cleaning and maintenance of the die head therefore is essential. Cleaning is carried out exclusively by experts: Industrial mechanics with further training as die head cleaning specialists ensure profes- sional basic overhaul. The new hall is equipped with the latest tech- nology: At five cleaning stations and two pyrolysis furnaces, more than 200 die heads are cleaned each year without damaging the material. All processes in the new hall are coordinated for particu- larly fast throughput times.
