12 Extrusion International 5/2018 INDUSTRY NEWS New Advertising Campaign “Art in Color Dosing” „ Moretto presents the new advertising campaign “Art in color dosing” dedicated to DPK gravimetric loss-in-weight doser, re- cently launched on the market. DPK completes the full range of Moretto’s dosers and solves the overdosing problem with a very precise control. DPK is a compact, loss-in weight precision feeder, suitable for intermittent or continuous dosing of small quantities of color or additives into a flow base resin. The advertising campaign focuses on the “precision in color dos- ing” and refers, with nice allusions, to the importance of color in works of art. The new advertising is clearly inspired by Pop Art and DPK is its “icon”, with ist characteristic compact design and transparent hopper. The campaign is promoted on the press, as well as web and company’s social networks. Thanks to the exclusive vibration immunity system, the machine control algorithm and the hopper removable from the dosing unit, DPK achieves a dosing accuracy upto ±0,03%, allowing processors to avoid unnecessary wastes of expensive additives. The integrated feeding systemautomaticallymanages the load- ing of the material, according to the needs of the processing machine. Moretto S.p.A. www.moretto.com NewCutter Hub for PelletizingHUB „ Bischof + Klein, a leading European producer of films and lami- nates, reports that new-design cutter hubs retrofitted on its pel- letizers have substantially increased blade life and improved pel- let quality. Bischof-Klein uses BKG ® underwater pelletizers from Nordson Corporation within their compounding lines to mix col- ors and additives for its film manufacturing. When the company installed Nordson’s new BKG ® HiCut™ cutter hubs on two of its pelletizing lines, the blades mounted on the hubs lasted two to three times longer than those of the older design, andwith some materials – particularly non-abrasive compounds – blade life was extended froma typical three days to nearly threeweeks. In addi- tion, the pellets producedwith the blades exhibited fewer “tails,” which subsequently separate from the pellet as fines, can abrade or clog equipment, and represent a waste of polymer. “Because Nordson’s new design increased the number of blades on the hub by a factor of 50%, we were able to reduce the rota- tion speedof the cutterwhilemaintainingour standardhigh level of throughput,” said Eduard Beifus, responsible for regenerates and concentrates at the Bischof + Klein site in Lengerich, Germa- ny. “This decrease in driving speed led to a reduction in wear to the blades and a substantial increase in their lifespan.” In anunderwater pelletizer, polymer strands emerge fromthedie plate, solidify as they enter thewater, andare then cut intopellets by the blades mounted on the cutter hub. The new HiCut design accommodates up to 100%more angled blades per hub and up to 54% more straight blades. This makes possible an increase in throughput or, alternatively, a reduction in pelletizer RPM, which decreases wear to the die plate and blades. “The blades on BKG HiCut cutter hubs have round edges and smooth surfaces with countersunk screws. This optimizes the flow and reduces swirling, and there is more space between the blades so that pellets do not accumulate,” said Frank Asmuss, global product manager for BKG pelletizing systems. “For certain products, the increased throughput achieved with the new de- signmakes it possible to invest in a smaller pelletizer, saving cost.” BKG HiCut designs are compatible with all existing pelletizer systems, and the hub accommodates both angled and straight blades.
