39 www.smart-molding.com molds and tooling A s plastic part design continues to push boundaries, and sus- tainability will be the future for all molders, challenges to injec- tion molding are increasing. Designed for low shot weights, ranging from 0.2 to 30 gr, the multi-cavity series from Oerlikon HRSflow is conceived to en- able maximum design flexibility and ensure tight production tolerances at the same time. Suitable for a large-scale produc- tion of injection molded compo- nents, it is the ideal solution when an outstanding surface quality and short cycle times are required as for example in: • thin wall packaging • beverage and home • beauty and personal care • medical parts • technical applications The minimum gate to gate pitch is up to 22 mm for open gate and 25 mm for valve gate with the smallest nozzle pocket of Ø 16 mm. Oerlikon HRSflow hot half is a fast plug and play solution for the injection molding machine. The in- ternal geometry is suitably profiled to guarantee excellent resistance to bending and torsion, even with high cavitation numbers. The dedi- cated channel design and the spe- cific coating significantly increase the wear and tear of components, performing also optimized corrosion resistance. The Company can offer conformal cooling circuits, conceived and built by in-house SLM Technology in case of challenging applications whatever the market segment destination. On the road towards environmental responsibility More and more companies are looking to reduce the environmental impact of their products by making use of recycled plastics. We provide for biopolymers and PCR resins dedi- cated technical solutions, as they are often characterized by narrow process windows due to thermal or shear sen- sitivities. Oerlikon HRSflow hot runner systems are furthermore conceived to prevent damages caused by foreign particles accidentally present in the bio or PCR compound. This allows to avoid any streaking or flow marks that could jeopardize the cosmetic and functional result of molding. Oerlikon HRSflow www.hrsflow.com Designed for low shot weights, our hot runner line for small applications combines maximum precision and fast cycle times with special attention to sustainability.
