Heavy parts for lively fish

“Aquafarming” or “aquaculture” is a designation of origin printed on many fish package labels in supermarket shelves today. Travelers who have flown over the coastal areas of Scandinavia, Latin America or the Asian island regions will have noticed the enormous growth of this branch of industry over the last few years. They can see how the fish farms extend across coastal waters in clusters of rectangles or circles. One of the most prominent producers is the Norwegian Akva Group. Its circular fish cages with diameters ranging from 13 to 64 meters consist of nets suspended from a circular float, which simultaneously functions as a service platform. The float consists of two concentric rings of HDPE pipes which are welded watertight and kept in position by brackets. These brackets are injection-molded parts made of HDPE, which weigh up to 50 kg and are manufactured by the Norwegian family-owned company PLASTO in Andalsnes. The large-volume injection molding machine needed for this purpose has been developed and manufactured by WITTMANN BATTENFELD in close cooperation with PLASTO.
