Hot runner solutions for luxury, sustainable, and compact applications
At K 2025, Oerlikon HRSflow presented its latest hot runner technologies tailored to the beauty and personal care industry. Engineered for luxury and sustainable packaging using the latest generation of PET and co-polyesters, these solutions addressed the growing market demand for premium aesthetics combined with environmentally responsible choices. In addition, the company showcased the new Up nozzle series, designed for tight-space applications with low shot weights.
Advanced technology for luxury, eco-friendly applications
At K 2025, Oerlikon HRSflow unveiled its innovative hot runner solutions, specifically optimised for high-end cosmetic packaging using the latest generation of PET and co-polyesters, including materials with a high percentage of recycled content fully compatible with the most stringent European PET bottle recycling streams.
Among the innovations on display were flawless quality results achieved using Eastman Cristal One Renew IM812, a recycled and recyclable resin offering a true glass-like shine. Thanks to molecular recycling, this material ensures consistent colour even with up to 100% recycled content and enables moulding of components with massive wall thicknesses, ideal for high-end, design-driven packaging.
In this demanding market segment, Oerlikon HRSflow supports mould design and optimal gate conditioning, provides rheological analysis for application-specific solutions, and fine-tunes the molding process. For special components, the company defines the ideal hot runner configuration and predicts part quality using its advanced Test Lab.
Up Nozzle Series for hard-to-reach gate locations
The innovative Up nozzle series allows direct gating in hard-to-reach areas, with a minimum gate-to-gate pitch of 15 mm and a 12 mm cut-out, making it ideal for compact applications with low shot weights.
Engineered for challenging gating areas, it is particularly suited for beauty and personal care applications such as caps, lipsticks, lip gloss, and mascara, and is optimised for cosmetic polymers with narrow process windows.
The Up nozzle series also handles demanding technical polymers, including PA and PBT, and has been successfully used in electronic components to eliminate the cold runner in most applications, says the company.
