Technology and simplicity made in Italy

The extrusion blow moulding machine model 550 in the new Isit series (an acronym deriving from the Italianisation of "easy" into "isi" plus "it" for Italy) was recently tested at the ST Soffiaggio Tecnica factory. The blow moulding machine, destined for a British manufacturer of technical components for the automotive industry, has a clamping force of 55 tons and incorporates an HEX extruder with diameter of 75 mm and L:D ratio of 30:1, which ensures a plasticization capacity  of 300-320 kg/h of HDPE. This range of machines stands out in particular for the new clamping unit with two diagonal tiebars for handling mould platens, driven by a single piston, and for the new high-performance, low-energy plasticization system.
