HRS Flow presents Flexflow technology and HRS Cool, a hot runner system without the need for water cooling of the associated actuators, at K 2019.
Family moulds for the cost and time efficient production of different parts in a single shot, have traditionally been associated with problems caused by traditional pin control methods, including poor balancing causing e.g. warpage issues. HRS Flow’s (Booth D05, Hall 1) hot runner technology provides a broad potential to improve the quality of the parts, to avoid cost for additional process tuning, to broaden the process window and to extend lifetime of the tool. Using servo driven valve gate technology to independently control stroke, timing and force of each individual pin, can overcome existing limitations in terms of close similarity in size, weight, wall section and volume, whilst ensuring all cavities are being filled simultaneously, preventing from overfeeding and flash formation.
Extended range of cylinders
At K 2019, HRS Flow will also showcase its recently extended portfolio of compact and small cylinders which require very limited installation space. New is a series of pneumatic cylinders which can be easily installed without removing the hot runner from the mould plate. Designed for excellent thermal insulation, they do not require cooling for a wide range of polymers. Thanks to the modular design concept and a reduced number of parts they stand out through easy maintenance. The cylinders are available with or without end stroke, as damped version, also with end stroke, and with pressure sensor.
HRS Flow will also present the SA Series, its smallest series of screwed-in hot runner nozzles for very low shot weights, with a very compact cut-out, dedicated to process small technical components and designed to have optimal thermal conditions for high flexibility in processing engineering polymers, even with high fibre loads or high viscosities.
Another highlight will be HRS Cool, the innovative solution for hot runner injection moulding, that allows to completely eliminating water cooling for the most common automotive applications. The design minimises the heat transfer from the hot tool plate to the cylinder, while a highly thermally conductive cover maximises heat dissipation from the cylinder to the cold clamping plate
Live presentation at partner booths
Visitors of K2019 will be able to experience HRS Flow’s hot runner technology on a couple of the company’s partners booths, including Sumitomo (SHI) Demag (Booth D22 in Hall 15), Krauss Maffei (Booth B27 in Hall 15), Wittmann Battenfeld (Booth C06 in Hall 15), Engel (Booth C58 in Hall 15), Yizumi (Booth C59 in Hall 14), and Arburg (Booth A13, Hall 13), all of them showing cutting-edge solutions for sophisticated moulding tasks.
