K 2025: Oerlikon HRSflow presents hot runner technologies for different applications
At K 2025, Oerlikon HRSflow will showcase its innovative hot runner technologies at its own booth and partners’ booth. Exhibits will include the groundbreaking STARgate HRS hot runner technology, new development of the Glow HRS solution, and application-specific solutions for multi-cavity systems.
MULTIflow HRS: New nozzle series and PET thick wall solution now available
With its compact gate-to-gate pitch (down to 15 mm), the new Up Nozzle series from Oerlikon HRSflow is specifically engineered for tight spaces with low shot weights. With a 12-mm nozzle cutout, the series delivers exceptional performance in hard-to-reach gate areas. The series is ideal for industries such as beauty and personal care, packaging, beverages, and technical applications.

At its booth, Oerlikon HRSflow will present crystal-clear, eco-friendly parts produced with dedicated hot runner solutions for luxury cosmetic packaging. These components benefit from advantages of the technology, including crystal clarity, significant wall thicknesses of up to 12 mm, and high process repeatability.

Newly developed STARgate HRS hot runner technology
This technology is a groundbreaking development in the injection molding of PP, PE, PS, and other amorphous thermoplastics. Compared to conventional designs, production, assembly, and maintenance of various components are unnecessary. Its cycle time is significantly reduced, color changes are easier, and power consumption and pressure loss are reduced.
Additionally, the thickness of the back plates can be reduced. STARgate HRS hot runner technology also enables short filling and packing times.
At K fair, this technology will be on display at BMB, an Italian injection molding machine manufacturer, during the production of a bucket. This project was made possible by Oerlikon HRSflow, BMB, the Dutch plastics processors Dijkstra Plastics, Oerlikon Balzers, Piovan and R&D Plastics.
GLOW HRS technology
Another innovation to be unveiled for the first time at K 2025 is the GLOW HRS technology, which enables the production of high-quality parts by direct injection, avoiding halos and weld lines.
With precise surface temperature control and a compact design, this cutting-edge solution easily adapts to a wide range of applications.
FLEXflow HRS servo-controlled needle valve technology for automotive application
At the booth of Haitian International Germany, Oerlikon HRSflow will give a live demonstration of how the FLEXflow HRS servo-controlled needle valve technology can be used to get high-quality automotive parts directly from the mold. This will be illustrated by the manufacturing of a car wheel arch.
Developed in collaboration with DNP Group and Inevo, this joint project impressively demonstrates that the painting of large-format injection-molded parts can be eliminated, minimizing the need for expensive post-processing, even when using recycled materials.
Other advantages of FLEXflow HRS technology include quick color changes and reduced material waste.
More live demonstration of advanced injection molding technology
More live demonstration of Oerlikon HRSflow’s hot runner solutions will appear at partners’ K booth.
At the Engel booth, a three-drop system from the Ga series of Oerlikon HRSflow’s Diamond Lux line of hot runner solutions will be demonstrated for producing a rear light concept application.
BOY's booth will feature the injection molding of a conical blood filter using a Jestar medical demonstration mold on a BOY 35E injection molding machine. This process utilizes Oerlikon HRSflow’s Multi Valve Plate (MVP) technology in conjunction with a 16-drop MULTIflow HRS system from the SP series. This technology offers synchronized valve actuation and reduced drop-to-drop spacing, enhancing precision in small weight applications.
