Is now a good time for local manufacturers to invest in new automated production technology?
In September 2026, Oerlikon HRSflow showcased an expansion of its STARgate HRS hot-runner technology to include a wider range of polymers. The system was demonstrated in Italy, where it processed various resins, including PMMA, ABS, and HDPE.
Why it matters
The expanded capability allows manufacturers to utilize advanced diaphragm gate shut-off systems for a broader array of plastic components. By optimizing melt flow and eliminating traditional actuator space, the technology helps improve production efficiency and material usage.
The system supports components ranging from 40 grams to 2.5 kilograms while utilizing a diaphragm-based gate shut-off. A trial run using a two-cavity tool to mold a 1.5-liter bucket achieved a cycle time of 4.7 seconds.
The players
Oerlikon HRSflow
This company is a global manufacturer specializing in hot-runner systems and injection molding technology solutions.
The details
The STARgate HRS technology uses a free-flow nozzle design to minimize melt stagnation and ensure consistent velocity through the cavity. Its unique architecture eliminates the requirement for axial actuator space above valve pins, allowing for more compact tool designs.
Timeline
September 2026: The Flow Beyond 2026 summit took place in Italy.
The Big Picture
This development updates the application range of the STARgate HRS hot-runner technology by extending its utility to additional polymer types. By refining diaphragm-based gate control, it marks a shift toward more versatile and space-efficient injection molding processes.
Manufacturers can anticipate potential cost savings through reduced cycle times and decreased material consumption for large parts. This technology enables more efficient production for consumer goods like plastic buckets and other components weighing up to 2.5 kilograms.
The takeaway
The implementation of diaphragm-based shut-off systems provides a path for manufacturers to improve output without increasing energy overhead. Integrating these systems can help streamline production cycles across a wider variety of plastic materials.
