Smart Molding International 4-2022

39 www.smart-molding.com molds and tooling For the manufacturing of the two covers from a PC/ABS blend in a family mold, a 2 drops screwed-in system was used. Moreover a 3D Design Film was overmolded on the covers. Particular attention was also given to the inner tray, the handle as well as the lateral latches made of PET RECOPOUND® by KURZ. The result was a stable and robust end product with illimited possibilities of decorations. Project partners were Arburg, Hofmann, LEONHARD KURZ, Oerlikon HRSflow. 2K Rear-Panel: futuristic smart automotive surfaces ENGEL (Hall 15) presented the injection molding of a smart 2K rear panel composed by a PC+ABS frame overmolded with PMMA or alternative PC. During the first injection phase a hydraulic 2 drops s y s t em f r om Oe r l i ko n HRSflow was used while for the second one a Single nozzle from Ga Series was employed. The part was finally decorated with a capacitive and aesthetic film directly in the mold for an innovative result. To implement such complex requirements, exact rheological analysis calculations were necessary. Project partners: ENGEL, Schöfer, LEONHARD KURZ, Röhm, Oerlikon HRSflow. 3 component coffee-to-go cup: hot runner solutions for 100% recyclable parts In Hall 15, Wittmann Battenfeld was demonstrating the manufacturing of a 3-component coffee-to-go cup with a lid. The rotational mold with 3 separate injection units was equipped with three different single nozzle systems by Oerlikon HRSflow optimized to process the 100% recyclable PP Bornewables™ ( nonpetroleum-based feedstock) from Borealis. The Bornewables™ - made of renewable raw materials derived from waste and residue streams - perfectly meet the functional requirements of the molded part without compromise in terms of quality and sustainability standards. The cup, with a thickness of 2 mm, is produced in clear optic in the first cavity and over-molded in the second cavity with an insulated shell. The insulating effect is obtained by foaming the melt through the special Cellmould ® technology which enables the production of lightweight, rigid parts without sink marks. Project partners were Wittmann Battenfeld, Haidlmair, Borealis and Oerlikon HRSflow. Garden tool: 2K irrigation connector Additionally at K show, Oerlikon HRSflow was showcasing at Billion’s booth in Hall 15 the injection molding of a garden tool, specifically an irrigation connector. The part was produced through a 2K tool equipped with two different hot runner systems with one nozzle. During the first phase, a face-to-face torpedo system was used to inject styrenic compounds (ASA polymer), while for the second phase, a screwed-in cylindrical valve gate system was employed to inject elastomer compounds (SEBS). During the second phase, the molded part could be easily customized thanks to the marking operations directly embedded in the tool cycle process. Among the special features the automatic and quick change of the mold version enabling the production of the three different components - in this case the coupling diameters - without disassembling the tool or stopping the manufacturing activities. Project partners were Billion, Groupe Pernoud, Actemium, Sepro Group, Resinex, Lifocolor and DeViris, Oerlikon HRSflow. High Gloss B Pillar: accurate injection, perfect appearance The Injection Molding Machine manufacturer Tederic (Hall 15) was showcasing the production of a high gloss B pillar. The molded part was obtained through a 2K hot runner system developed by Oerlikon HRSflow. The hot runner solution enabled the perfect appearance of the component thanks to a gentle, low-stress injection. During first phase a 2 drops conical valve gate hydraulic system combined with ICM Technology were used to inject PMMA polymer, while for the second one (ABS material) a 6 drops system was developed. The project was conceived in cooperation with Tederic, Yuyao Skymold, Piovan and Technotrans Solutions GmbH, Oerlikon HRSflow. Oerlikon HRSflow www.hrsflow.com
