TECHNOLOGY | HOT RUNNERS
Right: Hasco’s Streamrunner is an additively manufactured hot runner manifold offering maximum freedom of design
manifold makes for considerably lower shear stress in the material, resulting in better quality mould- ings. And the flow-optimised design speeds up colour changes too, since the melt can be divided and deflected over generous radii. Hasco says the complete absence of diverting elements means the Streamrunner can be pro- duced in a particularly compact design. Very tight spacing down to 18 mm is also possible for high cavity systems, depending on the application in question. The height of the manifold can also be restricted to 26 mm, making it considerably smaller than other manifolds on the market. Used in conjunction with separately controlled nozzles, the advantages of this unique system become even more apparent. At Fakuma, other Hasco highlights included new
integrated height adaptability ensures maximum efficiency even without accurate seat tolerances. Oerlikon HRSflow says HRScool Evo enables savings in costs and maintenance, because the elimination of liquid cooling reduces the number of components. The connection of cooling circuits is equally eliminated, as is the problem of clogged cooling ducts or the degradation of hydraulic fluids. Hasco launched its additively manufactured hot runner system at the K 2019 fair. Since then, a number of successfully implemented customer projects have served to confirm the advantages of the system, it says. The company has now adopted the name of Streamrunner for this innovative technology to enable its clear identification and differentiation. This was shown on the Hasco Fakuma stand in the form of a compact, fully balanced 20-fold system. The Streamrunner is an additively manufactured hot runner manifold offering maximum freedom of design. Using this technology, flow channels can be configured with the optimum rheological layout, avoiding sharp edges and areas with poor flow. The gentle passage of the melt through the

Primezone H1281 control units together with a new 4-fold control unit of the Basezone H1250 range. Both control units feature intuitive operation, precise control and maximum production reliabil- ity, says the company. It also presented the latest software update for the Primezone range. With the new group and select function, the controller can be parameterised and adjusted to new process conditions very quickly. The possibility of external control has been extended by two functions: in addition to standby operation, the boost and the zone heaters can be activated by an external signal.
